Come to think of it, I believe it was the slugs that ate them. I have such a variety of critters that take a liking to my plants I often forget what attacks what haha. The slugs were much more likely and now that I think back I'm pretty sure I recall seeing some of their slimy tracks along the edge of my planters that the zinnias were in!

Seed order arrived in the mail yesterday - not long now!
Have been reading more of this forum and admit to being somewhat intimidated by the complexity of crossing composite flowers as opposed to the simple ones with a single obvious stigma and obvious anthers. When you start talking about gathering green seeds and doing dissection - yikes! :) This forum has been around for quite awhile, so I'm hopeful there will be someone to go to with questions when the time comes.

Hi Alex,

"...admit to being somewhat intimidated by the complexity of crossing composite flowers as opposed to the simple ones with a single obvious stigma and obvious anthers. "

It is not at all complex to cross-pollinate zinnias. In the morning the pollen is expressed freely in the pollen florets, which contain the anther bundles internally, and the stigmas are readily accessible at the base of the petals. If you prefer to transfer the pollen with a brush, simply touch the brush to a pollen floret to get some of the pollen on the tip of the brush. That takes only a few seconds to do.

{{gwi:26423}}
Then touch the brush to the stigmas that you want to pollinate. A single brush loading can pollinate several stigmas.

{{gwi:26424}}
Or you can use tweezers or forceps to pick a pollen floret and use the floret itself as a pollen-bearing brush.

{{gwi:26425}}
And simply rub that floret against the stigmas that you want to pollinate.

{{gwi:26426}}
Regardless of whether you prefer to use an artist's brush, tweezers, twissors, or forceps to pick up the pollen, the pollen florets and stigmas are relatively large, easy to see, and easy to get at. You can pollinate a lot of zinnia stigmas in only a few minutes. Gathering green seeds is as simple as plucking out a few zinnia petals.

" This forum has been around for quite awhile, so I'm hopeful there will be someone to go to with questions when the time comes."

There is always someone to answer questions and don't hesitate to ask about anything that you aren't sure of. Regardless of which technique you use in pollination or seed gathering, it is easy to do. Zinnia seeds are relatively large and easy to handle.

ZM

ZM - I guess most of the issue with me is the multiple stigmas. Do you try to pollinate them all, or only some? And if you miss some, how do you designate which ones of the many you've done? How can you be sure later which ones are ones you pollinated and which ones are selfs, or insect-pollinated? Should I be removing the anthers on the seed parent, so as to narrow down the possibilities?
Thanks for your help! - Alex

Hi Alex,

"I guess most of the issue with me is the multiple stigmas. Do you try to pollinate them all, or only some?"

As you can see in this picture of a newly opening zinnia bloom, there is a yellow forked stigma at the base of each petal.

{{gwi:26427}}
Since zinnias are composites, the zinnia flower head is composed of botanically many flowers. A botanical flower is capable of producing a seed. At the stage of development in the picture, each petal is a flower all in itself and consists of the petal itself, the stigma and the unfertilized ovary. The stigma leads to the ovary. A pollen grain can stick to the stigma, germinate, and grow down the stigma to reach the ovary and fertilize the egg cell within the ovary, which can then develop into a zinnia embryo in a zinnia seed. Since each stigma that gets fertilized produces one and only one zinnia seed, I try to pollinate as many stigmas as I can, simply to increase the seed yield from that zinnia bloom.

"And if you miss some, how do you designate which ones of the many you've done?"

You are asking some good questions. I apply the pollen to the stigmas in the morning because that is when the pollen appears in the pollen-bearing "fuzzy yellow starfish" florets. Sometimes you can see some pollen that you put on a stigma, but usually you can't, even if you have gotten many pollen grains onto the stigma. But the next day you will see that the stigmas that got fertilized are wilting, withering, becoming brown and dead, while the stigmas that aren't fertilized yet are still fresh and perky little yellow forks. So you have a second chance to pollinate them. That continues for several days, so you have multiple chances to fertilize a stigma before it becomes too old to function.

If you are persistent in applying pollen over a period of several days, you can fertilize a high percentage of the stigmas in a zinnia bloom. As a zinnia bloom develops, it continues to produce new petals with stigmas, so some zinnia blooms can produce a lot of petals and produce a huge seed count if you manage to fertilize a high percentage of their stigmas.

New petals can overlap existing unfertilized stigmas, so you can lift up petals looking for unfertilized stigmas. I am right-handed, so it is natural for me to apply the pollen with my right hand while using my left hand to steady the bloom and manipulate the petals for access to the stigmas. A zinnia bloom can continue to develop over a period of weeks, so some blooms can produce a lot of petals and each petal is attached to a potentially fertilized seed. A bloom like the one in this picture can produce more than a hundred seeds, enough to plant a fairly large zinnia bed.

{{gwi:3319}}
Since a single zinnia plant can produce several blooms, a single plant could potentially produce enough seed to plant a large zinnia garden. Zinnias are potentially prolific.

"How can you be sure later which ones are ones you pollinated and which ones are selfs, or insect-pollinated?"

You can't be totally sure, but when you see the resulting plants you can have a pretty good idea which ones came from your pollinations, knowing the nature of the zinnia you took pollen from and the appearance of the female flower. You can place a "hairnet" over a zinnia bloom to keep the bees off of it. But I don't think that is necessary. You have a big advantage over the bees, because they aren't trying to pollinate, they don't know or care about the stigmas, and they are just gathering nectar and/or pollen. So any pollination they do is purely an accident. Whereas you are deliberately gathering pollen to place on stigmas, so you are an order of magnitude more effective than the bees.

"Should I be removing the anthers on the seed parent, so as to narrow down the possibilities?"

The anthers are inside the pollen florets, so you could remove those florets and discard them, or use them to pollinate a different bloom. I usually select my female zinnia blooms as ones that aren't producing a lot of pollen florets, so "emasculating them" isn't much of an issue. Good questions.

ZM - thank you kindly. I excell at questions; listening I am still working on. :) Your explanations are quite clear, and I have bookmarked them for future use - we will see what fruit they produce!

Hi all,

It helps when you are breeding your own zinnias to have some kind of goal in mind. It doesn't have to be a hard-and-fast goal, and you may see some zinnia that has a novel characteristic that causes you to set a new goal. As you get several zinnias in bloom, you will probably formulate several goals.

One goal I have is to develop a large zinnia with a very dark color. Not exactly black, but very dark. This bloom was a step in that direction.

{{gwi:26429}}
It had a fairly dark cerise-purple, but not nearly as dark as I want to go. In the 1930's and 1940's there was a zinnia strain named "Black Ruby" and it was very, very dark, but had small Cupid or Lilliput styled blooms. Sadly, Black Ruby is no longer available, and it may be extinct. I think it is scandalous that seed companies don't maintain safe storage of important zinnia varieties, but apparently they don't. Zinnias can have some very dark purple petal color, like on this Persian Carpet or Aztec Sunset specimen (I don't remember which it was).

{{gwi:26430}}
Persian Carpets and its dwarf plant version, Aztec Sunset, are cultivars of Zinnia haageana, which was crossed with Zinnia violacea (elegans) over a hundred years ago to create interspecific hybrids. Progeny from those eventually became the Whirligig strain, and since Whirligigs arose from an interspecific cross, they continue to show a lot of recombinatorial variation. This was a Whirligig specimen I had a couple of years ago.

{{gwi:26431}}
It has some fairly dark purple coloration, but not nearly as dark as the Persian Carpet purple, so I have a way to go before getting to a large very dark purple cactus flowered zinnia. I have been using Burpeeana Giants as my primary source of cactus breeding material, and that flower form has interacted with the wild Whirligig genes to produce some purples with a somewhat different flower form.

{{gwi:3327}}
That flower form has cactus influence and Whirligig influence, but it is essentially a different informal zinnia flower form. Unfortunately it started as a medium purple and faded with age to a lighter purple. So I have quite a way to go to get that big dark zinnia. I am flexible on the flower form. It doesn't have to be cactus flowered, and I would be quite happy with an informal flower form like in that last picture, or one of the variant flower forms that I have, like aster flowered. I also want the dark purple in a spider flowered form with white tips, but that is a somewhat different zinnia goal. It is fun pursuing specific goals in zinnias.

ZM

These are gorgeous - especially that last one! Not sure what specific goal I'd have - more, I know what I DON'T want. I'm not a fan of anything pom-pom - to me, a most un-flower-like shape.
I do like things that are picotee, but in a narrow band - a slight accent of lighter color. I can admire any single bi-colored flower, but when I imagine them as a drift of flowers in a bed, the feeling is that it's too much, too busy. Unless the colors are soft, muted and flowing.
I mentioned I prefer the cactus flowered zinnias - I'd say this is because they are graceful and flowing, not static and regular. Some of the pompom and other types seem too perfect to be real, if you get what I mean. Perfect, flawless symmetry in nature is a curiosity and draws the eye. Such things are awe-inspiring, but for me, it is the irregularities in an otherwise pleasing shape, color, arrangement,etc that
lend that touch of individuality that inspires a sense of Beauty. The "Snowflake Syndrome": if they were all alike, when I look outside I'd only be thinking to myself "Dang - it's snowing AGAIN!"...Wait a minute - that IS what I'm thinking! :)

Was thinking there was a pic of a zinnia from last year's garden - just found it. And just as you were saying earlier, here's a bee resting on it in the cooler morning temperature. This was in mid October.

Hi Alex,

That red zinnia actually is somewhat bicolored, suffusing toward magenta at the petal base. It may very well have distant Whirligig parentage.

"I can admire any single bi-colored flower, but when I imagine them as a drift of flowers in a bed, the feeling is that it's too much, too busy. Unless the colors are soft, muted and flowing."

I respect that. Although the bicolored (and tri-colored) petal coloration does tend to lose its drama from a distance. This is a picture of my south garden a couple of years ago, when it was devoted entirely to Whirligigs.

{{gwi:24469}}
From a distance you can still see the light colored petal tips, but things tend to merge together from a distant viewpoint. I didn't plant that garden for landscaping effect, but for breeding purposes -- hence the 6-foot wide paths and 4-foot wide zinnia beds. I adopted that layout to guarantee accessibility to the individual blooms for breeding purposes, and to leave enough space to get my wheelbarrow between the zinnia beds. As the zinnia plants develop, they spread out at least a foot, so that the 4-foot zinnia beds become 6-foot beds and the 6-foot paths become 4-foot paths. I plant the 4-foot beds as 4 rows spaced 16 inches apart, with two of the rows at the very edges of the bed. I used to lay out 3-foot wide paths, and they essentially disappeared as the zinnias developed, making access somewhat awkward and accidental damage to the zinnias fairly common. I will continue the 6-foot path 4-foot bed layout again this year. I have a fairly large garden, and I can afford to "waste" some space for the wide paths in the interest of convenient access.

"Some of the pompom and other types seem too perfect to be real, if you get what I mean."

I do get what you mean. In the past I have grown some Cut-and-Come-Again and Oklahoma zinnias for their branching plants, which most large zinnias lack, with the exception of the Burpeeana Giants, which have branching bushes as a design feature of the breed. So I do have some "pompon" genes floating around in my gene pool, and I occasionally get a flower like this one.

{{gwi:1838}}
My first reaction to it was that it didn't look real. And that access to its stigmas would be somewhat difficult. And that I could cut the bloom off with no stem and use it for batting practice.

I will continue to grow some of the Oklahoma variety for its branching plants. The Burpeeana Giants have been selected out of cactus stock for large bloom size and branching plants, but the old original version of the cultivar that was available in the 70s or 80s had better branching bushes, in my opinion. So that characteristic is worthy of further improvement. Plant form and flower form are important zinnia traits to me.

"From a distance you can still see the light colored petal tips, but things tend to merge together from a distant viewpoint."

I'll tell you what I'm seeing in that pic - a lovely absence of grass in between your rows. Sigh. I also plant in beds, but I limit their width to about 3 ft, as I am a small person and I discovered 4 ft raised beds were a bit of a strain for me to reach comfortably to the center. And I am stingier with my path space than you, wanting every inch possible for crops - they are also about 3 ft wide. Of course, I often regret it, as my husband, who does most of the rototilling for me ( he is not much into gardening, but he says it's his contribution for the food I grow), does occasionally take out a plant or two that's growing a little close to the edge. Understand, this only happens with things that have been direct seeded or are volunteers, and I've allowed the seed to grow where it has fallen. There's something delightful about having a volunteer nasturtium peaking up through the leaves of a squash. So much so, that I have taken to sowing flower seeds at random in the fall and spring in hopes of just such an event.

I think that pom pom you've posted is gorgeous! I would have to say it would be an exception to the rule for me. The coloration is amazing - the darker blush to the tips, the lighter center, and is it just the photo, or are the petals actually dark-lined around the edges? I hope you didn't use it for batting practice, but instead as a prized propagator.

You keep mentioning the Burpeeana Giants - I'll have to see if I can find an individual package when I go buy the whirligigs. I can see the future - less of the garden will be put to buckwheat this year than I originally planned, because I will need the space for zinnias. Ha!

Hi Alex,

"... is it just the photo, or are the petals actually dark-lined around the edges?"

They are not dark-lined around the edges. The edges of the leaves are slightly thicker than the inside of the leaves. It is almost like the edge cells themselves may be bit fatter. In any case, that dark line you see is actually a shadow of that thickened edge. It barely shows in that photo, but the zinnia leaf edges actually have some tiny white bodies that appear spaced maybe an eight of an inch to a quarter of an inch apart at the very edge. I think they serve some function, although I have no idea what. I have noticed them for years, but those white dots on zinnia leaf edges remain a mystery for me. A botanist might know exactly what they are. Unfortunately my knowledge of botany is very limited. If you look closely, you can see the white dots on one leaf in this picture.

{{gwi:26433}}
Not all zinnia leaves have them, but they aren't extremely rare. That zinnia happens to be one of my "toothy" strain, which I hope to improve a lot. Some of the toothy specimens can be rather spectacularly different from the ordinary zinnias.

{{gwi:26434}}
Every time I go inspecting my outdoor zinnia garden I will see some unusual little quirk in a zinnia that suggests a breeding goal in a new direction. Some people might say that I have "too many irons in the fire", and they could be right.

"I hope you didn't use it for batting practice, but instead as a prized propagator."

I didn't use it as a breeder, and it didn't put out any pollen of its own, so it didn't set any seeds. The pom pom flower form can be rather spectacular in the large sizes like that one, but "they aren't my cup of tea". I do like the scabious recombinants that have a big full center, like this one.

{{gwi:26435}}
Sometimes that scabious center can become a bit disorganized, like this one.

{{gwi:24662}}
If you look closely, you can see that that one has some bicolored Whirligig heritage in addition to its Scabiosa flowered heritage. When you cross-pollinate some of your slightly unusual zinnias, things can get a bit weird.

"You keep mentioning the Burpeeana Giants - I'll have to see if I can find an individual package when I go buy the whirligigs."

Sometimes you can find the Burpeeana Giants on the seed rack in Walmart. Of course, you can always order them direct from Burpee, although they cost a bit more that way.

A word popped into my head in connection with your description of the white spots on the leaves - "stomata". I didn't check it right away, but I just now went to see if I was right, and I'm pretty sure I am. Those are specialized pores for the release of gases. BTW, I really like the white "toothy" hybrid in that pic. You said you'd like to come up with a different name for it - you could go with the latin: dentem. I don't know latin, you understand, but pieces of things stick in my head, sort of like the stomata thingie, and I remember "dent-" being associated with teeth. Maybe you could vary it a bit and say "dentic" or some such. It's the common practice, afterall, in botany to use latin nomenclature that is recognized world-wide. Those Romans really got around.

The purple one pictured next looks much like my centaurea montana - I love these primarily for their rich blue color, but also for their hardiness and self-seeding tendencies.

The scabious form is wonderful, too. It would be too much work to post here for you, but a graph like a family tree to show how you got to a particular destination, would be fascinating to see.

Apologies for the quality of the photo - it's from an old pic and I had to adjust size, but couldn't get it any sharper.

That's exactly how this thread gets you. You discover you can walk into a hardware store, pick up a half dozen different shapes and varieties, and by the end of the summer, you can have as many as four different generations going at once. Zinnias are really interesting in their flexibility. With enough effort, it seems like you can make them look like almost any other native wild flower.

Except blue ones, unless I get really, really, really, really, really lucky.

Hey Mister Guy - if you come up with a blue, I definitely want to see it! Now that would be something to strive for. But I think I'll start small - like maybe see if I can make ANY successful cross - ha!

Hi all,

I have alluded to the scabiosa flowered zinnias in past messages without specifically recommending them. They are "not for everyone" for several reasons, which I will mention in a moment, but some of you might want to try them anyway. A lot of seed racks don't have them, although I have bought them off of a seed rack in the past. I will link in a couple of online sources (there are several sources in addition to the ones that I am linking to.)

There are at least two strains of scabiosa flowered zinnias available today, although many seed companies do not offer either of them. They are not considered to be a "main stream" zinnia, and many people do not even know they exist. Apparently the oldest available strain is the Scabiosa Flowered zinnia. I am linking to Thompson & Morgan because they are the only company that I know of right off hand that offers both strains. And if you have a T&M seed rack in your area, you might be able to find them there. T&M refers to that strain as "Scabious flowered" which is, in my mind, slightly quirky.

The other scabiosa flowered zinnia strain is Candy Mixed, which is a newer strain that was introduced only a few years ago. T&M claims Candy Mixed as an "exclusive", but I kind of doubt that. I plan to grow some of each strain this year just to widen my gene pool. The Candy Mixed flower size is slightly larger than the Scabiosa flowered strain, but both strains have smaller flowers in the 1-inch to 2-inch diameter range.

Both strains suffer from the disadvantage that a lot of them don't come true to their description. I have grown beds of the original Scabiosa flowered strain that had as few as one in 20 "on type" specimens. For the average gardener, that would be completely unacceptable. As an amateur zinnia breeder, I am delighted to get one "good one" in twenty plants, because I can do a lot with that good one. Incidentally, the "off-type" scabious specimens are little single, semi-double, or double Cupid, Lilliput, or Pom Pom types, all bearing conventional "fuzzy yellow starfish" pollen florets.

The on-type scabious specimens have several good traits, the main one being that their florets are not "fuzzy yellow starfish" but have petal color and texture. I have no idea how or when that mutation occurred, but scabious zinnias have been around for many decades.

And they have other advantages, that you might not notice at first. Their plants are very well branched, which results in nice upright bushes. Alex, they wouldn't look out-of-place in that picture of mixed flowers that you posted a few messages above. The scabious plants have a kind of "wild flower" look.

The scabious plants also have a structural advantage, in that their branches do not leave the main stem at a right angle, but have a more slanted acute angle of attachment that is inherently a stronger joint. That is one disadvantage of the bushy Burpeeana Giants strain -- their side branches are cantilevered at right-angle attachments that aren't as strong as they should be, and their branches can break off when brushed by a passing dog or a storm with severe winds. It's not a deal-breaker for me, and I will continue to grow a lot of Burpeeana Giants, but I will be selecting for stronger branch joints with them. And I think that mixing in some scabious genes could help them in that area.

To me, it is worthwhile breeding in the scabious strain just for improvement of plant form and structure. And, of course, with cross-pollination, the scabious genes can lead to a whole spectrum of new flower forms, which was my prime motivation for making crosses involving them in the first place.

More on this subject later,

Faisalpappu - I'm happy I stumbled across this group as well. People who know me well, know better than to get me started talking on the subject of gardening, unless they are equally as plant-crazy.
This morning I awoke to more of the same 6 degrees F temps, and the promise of 15 degrees BELOW for the early morning hours. Enough already! One of my few consolations being that Saturday is March 1st, when I shall start some of my first seeds under lights.

Hello faisalpappu,

Welcome to this zinnia hobby message thread. I invite you to include some zinnias in your gardening this year and report on them in these message threads. And post pictures. We would be interested in what it is like to grow zinnias in Italy.

ZM

Hi all,

This is a "second installment" on my comments about possibly including the scabiosa flowered zinnias in your breeding program. Referring to this picture of Candy Mixed on the Park Seed website, you can see that the first row of petals on a scabiosa flowered zinnia are more or less conventional zinnia petals, with accessible stigmas that you can apply zinnia pollen of your choice to. (You can also see that Thompson & Morgan do not have an exclusive on this variety. Grin) I like it that Parks includes an off-type specimen in their photo, because you can expect a lot of off-type specimens in any commercial scabiosa flowered zinnia strain. I plant them fairly close together (maybe 6 inches apart) knowing that I will be pulling out a lot of them and discarding them as culls.

As a slightly off-topic comment, I especially admire the copy writer(s) at Park Seed. The Park Seed descriptions of their zinnia seed varieties, and their offerings in general, are especially detailed, original, and helpful. In my opinion, Park Seed's website and, to a lesser extent, their paper catalog, would be a top contender for well written descriptions. And I hasten to add that I am not associated with them in any way, other than as a repeat customer.

But back to the scabiosa flowered zinnias. Their guard petals are your "way in" to breeding with them. The specimens that do have pollen florets are off-type, and for that reason I wouldn't use those florets for any cross-pollinations. In fact, I consider the pollen-bearing scabiosa zinnias as culls, so I pull them up and discard them. That makes more room for my "good zinnias".

The scabiosa flowered zinnias have small blooms, so I almost always cross them with larger zinnias. If there is some advantage to crossing them with cupid or Lilliput or pom pom zinnias, I will probably miss out on it. My primary pollen sources for cross pollinating scabiosa flowered zinnias have been Burpeeana Giants and Whirligigs and some larger flowered Whirligig x Burpeeana hybrids. Some hybrid results have much longer guard petals, which makes the bloom larger.

{{gwi:26436}}
In many recombinations, both the florets and the guard petals become larger.

{{gwi:26437}}
Sometimes the central floret area becomes much larger than is typical in the original scabiosa flowered variety.

{{gwi:26438}}
That specimen was produced from one of my first scabi x Burpeeana crosses, and it "bowled me over" and "fired me up" for my zinnia hobby. I referred to it as "sunflower flowered" because of its large crested center, which produced an abundant supply of selfed seeds in that center. It is now a distant ancestor of many of my scabious forms. Sometimes the size increase applies just to the crested center and the "original" guard petals are almost lost in the result.

{{gwi:26439}}
That kind of recombination can produce almost pom pom like flower forms.

{{gwi:26440}}
When the petals are fairly long and the centers are medium sized, I refer to that result as "Echinacea flowered".

{{gwi:26441}}
There is a whole spectrum of recombinations possible, resulting in flowers of various sizes.

{{gwi:26442}}
I feel that I have just scratched the surface in my exploration of what the scabious zinnia genes can do in various recombinations with other zinnia genes, especially what could happen when some of my other mutant genes become involved. I will explore that, and some more scabious recombinant forms in a later message. And there are some interesting complexities in the scabious flower form that I will discuss.

Wait a sec - which are the guard petals?
I'm really liking these scabi-formed zinnias. Dang - do I have to add a packet of those to the list as well?!

Hi Alex,

"...which are the guard petals?"

They say a picture is worth a thousand words.

{{gwi:26443}}
"...do I have to add a packet of those to the list as well?!"

It couldn't hurt. As long as you know you will be culling quite a few of them. The mere fact that their florets are petal color is an important feature to add into your gene pool. After you cross the scabis with a few other things, you can get an interesting variety of variant flower forms appearing.

{{gwi:26444}}
You increase the range of variation of your zinnias by making your own hybrids, and then making crosses between those hybrids.

{{gwi:24479}}
By crossing Whirligigs with scabious specimens, you can get subtle two-color transitions in those big guard petals.

{{gwi:1812}}
The guard petals can get large and shaped a bit, and the individual central florets can get larger.

{{gwi:26446}}
One of my goals this Summer is to get some really huge scabious florets, so that each floret is like an individual flower. That is actually the same theme I am working toward with my tubular and star-tipped petals. I want each zinnia bloom to be an explosion of individual flowers. And if I make some significant progress in that direction, I can throw some of the toothy petals into the mix. I have a witches cauldron in my mind when I am planning my zinnia crosses.

"Bubble, bubble"...
Very nice pics - I am totally down with what a guard petal is now. And in awe of the variety your crosses are producing. Here you can picture me rubbing my hands together in gleeful anticipation - and a definite sense of impatience, since I realize that it will most likely not be next year, but the year after before I see anything remotely exciting. But then that's gardening for you. Plant a perennial seed or a tree seed and wait years sometimes for them to germinate, and then further years to see the first bloom! ZM - you, MG, and some of the others are giving the season a boost with the indoor gardening. I may start a 6 pack-worth or two under the lights in April, then move them to the greenhouse until planting-out time. Typically, I do this with my other plants: light table, followed by greenhouse with gradually increasing hardening-off excursions outside in flats if the weather is nice, though back in the greenhouse at night. Finally being planted out after frost or just before final frost date with provisions for covering at night close at hand if necessary. Do you think this will allow me time to have 2 generations?
- Alex, the ever hopeful

Hi Alex,

"Finally being planted out after frost or just before final frost date with provisions for covering at night close at hand if necessary. Do you think this will allow me time to have 2 generations? "

I think there is a good chance of it. It is definitely worth a try. You are in zone 5a and I am in zone 5b by the old zone map, although I may be in zone 6a in the revised "climate change" map. So your climate is a bit colder than mine and perhaps your growing season a few days shorter than mine.

But here is the plan. Zinnias bloom in about 6 weeks from seed, so you will see first blooms fairly early on, especially from those that you gave an early start indoors. First bloom will give you an opportunity to cull some that you just don't like. Any commercial scabiosa flowered zinnias that throw conventional "fuzzy yellow starfish" pollen florets would be a candidate for first bloom culling.

Take a day or two to "size up" your first blooms and then decide on which ones you want to cross pollinate with which ones. That decision will be strongly influenced by which ones have available pollen florets and which ones don't. It may be a few days before you have available pollen florets on zinnias that you like. The stigmas are receptive pretty much as soon as the petals open. Just pick pollen florets with tweezers or whatever and rub them on stigmas. You will do that in the morning shortly after the little "light bulb shaped" floret buds open their fuzzy starfish arms. As is convenient for you, cross-pollinate your favorites every morning, and mark in some way which blooms have received pollen. I will discuss in some detail how I do that in a later message. But you will find some way that works for you.

In any case, keep track of which zinnia blooms have stigmas that you have successfully pollinated, as indicated by the stigma shriveling and dying. About three weeks after that happens there will have been enough time for the embryo in the seed at the base of that petal to have developed enough to have produced a "fat" green seed on that petal. The petal itself may very well be alive and well, and still retaining reasonably good color. You will learn to "rifle through" a zinnia head to find the fat green seeds, and pick them one petal at a time. Plant them the same day you pick them to get your second generation started as soon as possible. You will probably be harvesting and planting green seeds over a period of weeks.

As those green-seed plants grow and bud out and begin to bloom you will enjoy the anticipation of seeing your first hybrid zinnias open up. That can be exciting. But then you will treat them the same way as your first generation. Promptly self and/or cross pollinate your favorites, label them, and as their green seeds "fatten up", pick them and dry them on an old newspaper or something, and after a week or two they should be dry enough to store. I store my seeds in Snack sized Ziploc bags with an included 3x5 card describing the seeds.

The green seed technique is your "secret weapon" for getting in two generations of zinnias outdoors. The green seeds that you save and dry in the Fall with be your first F2 generation, capable of remarkable and surprising recombinations of genetic traits. But this year will you have the experience of seeing your very own F1 hybrids, which themselves can be quite new and different. And you will have that "witches cauldron" experience of deciding which ones to cross with which ones, with the expectations of many surprises from them.

I'll go into more details of the process in subsequent messages, but I think that by fully exploiting the advantages of the green seed technique you have a good shot at two generations of your own zinnias this year.

Incidentally, I should credit Jackie Rosales, who has posted in these zinnia message threads many times as jackier (JackieR), for the tip about using the green seed technique for an early save of zinnia seeds in the Fall. Prior to that, I had used green seeds as a quick way of starting the next generation, but I had been saving my Fall seed crop the "old fashioned way" of waiting for the seed heads to get brown and dry in the garden. That "old way" had several disadvantages, including exposure of the seeds to seed-eating birds and water damage from rain. Several species of Finches seem to have an appetite for zinnia seeds, and rain can cause seeds to pre-germinate in the seed heads. When you are saving brown zinnia seeds and find a little dried root sticking out of the seed tip, you can toss that seed, because it is dead. Green seeds don't pre-germinate in the seed head, even in extensive rainy periods, because their seed coat is still living, and not permeable to water.

There is a reference to these zinnia breeding message threads in the book, Plant Breeding for the Home Gardener, and JackieR got a write up on page 81. The book seems to be reasonably priced. There is another book that has a whole chapter on zinnia breeding, but it is expensive.

ZM - OK, you've convinced me to try the green seed technique. It goes against my normal inclinations, but as it has been tried and proved successful, then I will proceed in good faith. No doubt I will have questions at the time, but right now this is bolstering my self confidence... (and taking up the time until the more than 2 ft of snow melts out there.)
As consolation prize for the fact that it is now March and they are STILL predicting below zero temps in the next few days, I ordered from T&M last night: scabious flowered Zinnias, Whirligigs, and Green Envy. (Think I remember you suggested to someone, probably MG, that it might not hurt to include it in the breeding in search of a blue zinnia.)
The moon is new today and in a water sign, so I may be pre-germinating my eggplants and peppers tonight. I've gotten to where I pregerminate all but the smallest seeds in damp paper towel in a polybag, since they tend to germinate faster and I can see which ones are good before I ever put them in their cells or cups.
- Alex

Hi Alex,

"...and taking up the time until the more than 2 ft of snow melts out there."

Omigosh !!! Are you in freakin Alaska ??? We had 9 inches of snow and it melted off nearly a week ago. It had drifted over our driveway maybe 18 inches in places, and gave my snow blower a good challenge. But I usually have to fire it up only once or twice a winter.

"...you've convinced me to try the green seed technique. It goes against my normal inclinations, but as it has been tried and proved successful, then I will proceed in good faith. No doubt I will have questions at the time..."

And I will have some questions, too. In the past I have just planted my outdoor-pulled green seeds petal and all, with no attempt to breach the green seed coat to speed up the germination. This year I will experiment with breaching the seed coat, the same as I always do indoors. I may even experiment with the outdoor planting of embryos. I am curious whether an embryo can survive in garden soil, without the protection of Physan 20 and the sterile growing media that my indoor embryos have had. But in the interest of saving time, I will probably continue to plant most of my outdoor green seeds petal-and-all and just wait for nature to take its course to break down the green seed coat.

"...I ordered from T&M last night: scabious flowered Zinnias, Whirligigs, and Green Envy."

I have decided to take my own advice on crossing with green zinnias. I didn't have any Green Envy on hand, but I found a packet of Burpee's Tequilla Lime in a drawer, so I planted some of those, and they are getting their first true leaves now. I should be cross-pollinating them sometime in April.

I'm glad you decided to try the scabis. I think that scabi genes are responsible for a lot of interesting new variations in zinnias, and I will be curious to see zinnia variations that you get.

"The moon is new today and in a water sign, so I may be pre-germinating my eggplants and peppers tonight. I've gotten to where I pregerminate all but the smallest seeds in damp paper towel in a polybag, since they tend to germinate faster and I can see which ones are good before I ever put them in their cells or cups."

I don't garden by the moon myself, but I have experimented with pre-germination in damp paper towels. Some zinnia seeds show a root in just a day. I have had some experiences with the root getting too long and curved to make it easy to transplant the tiny seedling without damaging or breaking off the root.

But the advantage that you mentioned about seeing which seeds are good and avoiding committing a small pot to a dead seed is real, and perhaps worth the effort of pre-germinating. I think I will return to some experiments with pre-germinating. I could even try pre-germinating green seeds and even "pre-germinate" some zinnia embryos.

ZM

Last section first: most definitely go with pre-germination. I cannot speak too highly of the practice. I'm not sure where or when I first heard of it and started doing it, but if you are checking the seeds daily - and if you're like me, you can't resist checking their progress daily - you can generally catch anything before it gets so embedded in the paper towel as to risk damage with removal. But even then, I have successfully saved the seedling by clipping around the embedded root and then planting the seedling, paper towel shred and all. I've even started some very small seeds that way, and have ended up planting an entire clump of seedling/paper towel shred into the cell or cup of starting mix. After they've grown a bit, I can more easily separate them and/or thin them by nipping some of them out.
Another thing I started doing last year, was nicking some seeds, especially hard-coated ones, with a fingernail clipper. I discovered this after I decided I wanted to start a large quantity of Heavenly Blue morning glories. Normally, I paper-sand the seed and then soak them to help them break dormancy, but doing this effectively with a large number of seeds seemed too time consuming, so I hit upon the idea of making a small nick in the edge of the seed coat with the fingernail clippers, just enough to allow moisture to penetrate into the embryo. The germination on the morning glories was almost 100%, and it was old seed. I went then and nicked all my squash seeds and other seeds with a tough coats - germination was greatly improved! I bet you could simply nip the dried green zinnia seeds to help them get going. Best to remove the petal, though if pre-germinating in the paper towels, simply because of the risk of introducing more bacteria with the rotting petal.
Gotta go, talk later - Alex

Hi Alex,

Your pregermination hints are most welcome. I should have thought of simply cutting out a piece of paper towel and planting it with the seed when a root becomes involved. I have been nicking some of my dry zinnia seeds, and all of my indoor green zinnia seeds, but I use an X-Acto knife with a curved blade. That lets me slice off just a bit of the edge of the seed. I also trim the seed where the petal attaches. If I want to extract the embryo, I slice the other edge, and the seed can open like a book to expose the embryo. Anyway, thanks for bringing pre-germination to my attention. I'll definitely start using it, using your tips about including part of the paper towel with the seed when it helps.

Speaking of paper towels, I once did some experiments with making my own seed tapes using paper towel strips and gluing the seed to the paper towel strip with a dot of Elmer's school glue. I also tried using toilet paper for something that disintegrated better in the soil. I abandoned those experiments as not worth the trouble, but I notice Parks sells seed tapes of several flowers. Their seed tapes are undoubtedly made by machine. Maybe I should try gluing seeds to string or thread when I really don't have anything to do.

Back to the scabiosa flowered zinnia thing. The scabi hybrids normally give you a nicely larger zinnia with the florets in the central area, like this one for example.

{{gwi:26447}}
I guess we are calling that central area the "crest" because there was once a zinnia strain named "Howard's Crested" that was essentially a large scabiosa flowered variety. Howard's Crested has been extinct for many decades. Too bad, it would have been great for breeding with. But, anyway, crossing your crested hybrids together can result in strangely different stuff going on in the center of the bloom.

{{gwi:26448}}
In that one, through the magic of genetic recombinations, the florets have morphed into petaloids. The petaloids have properties of both florets and petals, but are different from both, and the seeds attached to them are often rather un-zinnia-like, too. I think the petaloids qualify as yet another zinnia flower part, and they have potential for creating new looks in zinnia blooms.

ZM - Back to the beginning of your former post - "are we in Alaska?" - Nah, just the middle of MI - Alaska is probably warmer right now! Seriously, this, overall, has been the worst winter in decades. We've had winters with colder temps (-21 is the coldest I've experienced), and winters with more snow (more like 3 ft deep), but this winter is the worst for being consistently cold, with no significant warm-ups, and no chance for the existing snow to melt. And here it is March, and they're still predicting overnight minus temps. When it occasionally warms up to 20 during the day, we all breathe a sigh of relief.
Yeah, I've looked at the seed tape idea and thought there would be some merit to it in the sense that it would keep lighter seeds (lettuce, carrots, etc) in place when the beds are watered or rained on right after planting. Many's the time I have inadvertently washed my seed down the furrows, ending up with clumps of carrots growing together where they have floated.
But I've never wanted the extra expense, and I guess I will have to pass on the idea of making my own. We have cats and the combination of cats + seeds + strips of paper and/or string + glue = disaster!

"The scabi hybrids normally give you a nicely larger zinnia with the florets in the central area" - how large are we talking? Are they almost as big as the cactus ones? I do like the bigger blooms. Oh, and off the subject, but how are you italicizing the segments you've taken out of my text? Are you writing up your script in a word doc first and italicizing it there? I can't see an option up there to change text while writing in the forum box itself.
That last pic with the petaloids is pretty cool. That would be an effect I'd want to work on. Well, hopefully, it won't be too much longer. Unless the poles have truly shifted and the scientists aren't telling us, as they are busy packing to move to the Arctic which is going to be the new California.

Hi Alex,

Well, we had a light snow last night and it is 4 degrees here headed for a high of 8 degrees. It was minus 6 last night. So it is not exactly Spring here either, although I do have zinnias in bloom thanks to the indoor gardening thing.

" "The scabi hybrids normally give you a nicely larger zinnia with the florets in the central area" - how large are we talking? Are they almost as big as the cactus ones? I do like the bigger blooms."

I have had a lot of them as large as the "large" cactus zinnias, in the 5-inch class. So far none in the "giant" 6-inch class, but that might be possible by backcrossing to large examples of the Burpeeana Giants. Some of the Echinacea flowered specimens get quite a bit of diameter from extra long guard petals.

{{gwi:26449}}
That one obviously had some Whirligig heritage. Some of the Whirligigs have extra slim petals, like this one.

{{gwi:26450}}
The Whirligigs can transmit some of their petal shapes into their hybrids, as well as their bicolor coloration. It would be interesting to see how big you could get the scabi blooms by repeated backcrossing and repeated selection.

"Oh, and off the subject, but how are you italicizing the segments you've taken out of my text? Are you writing up your script in a word doc first and italicizing it there? I can't see an option up there to change text while writing in the forum box itself. " No, I am not doing anything in an external text editor. Everything happens right here in GardenWeb's Message editing box. Fortunately GardenWeb allows limited use of HTML (Hyper Text Markup Language) in their message text. That gives us quite a bit of control over the appearance of our text, lets us insert hyperlinks (like the Test forum link in the next paragraph), and it lets us insert pictures inline, rather than at the bottom of the message, as occurs when you use GardenWeb's image insertion feature.

I use the HTML "blockquote" command to format my text in a narrower column than the standard forum text column.

I tend to be wordy, so I put my text in a narrower newspaper style column. GardenWeb has a Test forum where you can experiment. You can find out more about HTML online, and there are books on the subject.

ZM - Well, who says you can't teach an old dinosaur new tricks?

Don't expect any great leaps as yet, though - no jumping through fiery hoops or such like. (sigh - we have entered the new age, and there is no going back...)

Anyway, it was supposedly minus 17 out there this morning. I say supposedly, because our thermometer is located on our north porch right outside the livingroom window, and at present the porch is barricaded with a straw bale castle for the sake of the feral cat colony who are wintering there. Very long story as to why they are there, and not for this forum. But the happy news is that our temps read around 5 degrees - cold, but a significant difference from minus 17. The straw "castle" is probably keeping the house warmer as well. We heat with a wood stove (though we have a propane furnace - don't like it, gives me a headache - and costs more $$ as well), and have been through more than 4 full cords (12 face cords) worth of wood. Normally we would only have gone through 3 cords by this time.

Back to zinnias - sorry for the long aside. That one pic does look very echinacea-ish. Nice. What kind of bulbs have you got in your lighting system? I'm working with a very antiquated 8 ft double florescent fixture. In the beginning I was in the big city and could more easily locate the high intensity bulbs that were in it when I bought it from a friend. Since then I have had to settle for lesser strength bulbs - they work, but I know they're not close to being as effective. Now I am getting nervous that the ballast on this thing may be nearing its end. When that happens, I am definitely going to 4 ft fixtures, as this 8 ft is a pain in the a#@ to work around.

[blockquote][blockquote]Hi Alex,

I am echoing my HTML in square brackets, so that you can see exactly what is going on in my message, HTML-wise. I use copy-and-paste to insert the blockquotes, and link information, but the rest of the HTML is easy enough to just type in.

We had about 3 inches of snow total yesterday, and it is cold here -- below zero last night, slightly above zero now, and heading for a "toasty" 17 today.

[I]What kind of bulbs have you got in your lighting system? I'm working with a very antiquated 8 ft double fluorescent fixture.[/I]

I use Phillips T8 4-foot fluorescent bulbs. The T8s draw 32 watts each, and they are more efficient than the old T12 bulbs. I buy them in boxes of 10 bulbs at Home Depot, because they cost much less that way. It costs almost twice as much to buy the bulbs individually. They are available in several "colors" and I prefer the cooler colors. Most of my bulbs are either Cool White or Arctic White, and both of those have a color temperature of 6500K (Kelvin). I have a few warm white bulbs in service, which have a color temperature of 3000K and have a very warm colored light, very similar to regular incandescent bulb light. Most of my bulbs are rated at 30,000 hours, which is about 8 years of "normal" usage. My bulbs typically outlast the ballasts in my economy grade fluorescent fixtures.

When a ballast "goes" in one of my fixtures, I simply replace the ballast with a better one. That is a fairly easy DIY job (do it yourself), but you will need a few tools from Home Depot -- primarily a combination tool that cuts wire, strips insulation from wire, and crimps wire connectors. You also need a Phillips screwdriver to disassemble and reassemble the fixture. As the British say, easy peasy.

My fixtures have always been the lowest priced Commercial Electric (a store brand of Home Depot) fluorescent shoplights. Back in 2004 you could get one for about $4, which was a tremendous bargain, because the replacement electronic ballast (Park SL15) sold for about the same price. The fixture was essentially free, and people snapped those up rapidly. I missed out on the $4 bargain, but did get a few fixtures at $6 before the price went to $8, where I bought most of mine. Since then, the fixtures have been redesigned to make them slimmer, (a big improvement in my opinion) and they now cost a bit over $12, which considering inflation, is still a great bargain. I highly recommend them.

Neither of our local Home Depots keep them in stock for some reason, so I buy them in lots of 4 from the online central Home Depot store. Buying them in lots of 4 qualifies you for free shipping. They don't include bulbs in the fixtures, but you can get the T8 bulbs locally.

In case you are interested, here is the link to the Home Depot store for those shoplights. Here comes a little more HTML, first the "fake" in square brackets and then the actual in angle brackets.

[a href="http://www.homedepot.com/p/Commercial-Electric-Basic-2-Lamp-Hanging-Fluorescent-White-ShopLight-CESL401-06/203725913"; target="_blank"]Home Depot Shoplights[/a]Home Depot Shoplights

My growing units consist of chrome wire shelving with 2-foot by 4-foot shelves, about 6-feet high, and 4 of these shoplights light one of those shelves nicely. I am planning to light another shelf, so I will be buying four more of those shoplights for myself in the next day or two. They usually arrive in about a week. I already have the T8 bulbs on hand and some zinnia seedlings that would like to be re-potted to that shelf.

Well, I guess I will "throw in" another gratuitous picture of a scabi recombinant zinnia, just to show the HTML involved in doing that. First I will turn off this "newspaper column" thing, so that the picture can show in full width, and then restart the column formatting after the picture.[/blockquote][/blockquote]

[img src="http://img.photobucket.com/albums/v608/MaineMan/550%20Garden%20Web/100b5780_zps08de934b.jpg";]

{{gwi:26451}}
[blockquote][blockquote]Well, that wasn't very hard to do. Copy and paste can save some tedious typing. The red in that zinnia is rather muted. I never cease to be amazed how many different colors and shades that zinnias can have. They must be capable of well over a hundred distinct colors. I think that one has some purple toward the base of the petals from Whirligig heritage.

Well enough for now. I will discuss the subject of "overdriving" fluorescent fixtures in another message. Modifying a fixture to overdrive it nearly doubles its brightness, but to get that increase in light output, you have to install another ballast. Each bulb gets the output from a two-bulb ballast. The bulbs (tubes) get almost blindingly bright, and distinctly warmer to the touch, and it probably decreases their life as well. But with 30,000 hours of life, they are a little bit like a cat "with nine lives". The ballasts are "loafing", because they are driving only one bulb instead of two.

Well, more later. I won't forget to "turn off" this newspaper column formatting now, as the very last step in this message. And before I Preview the message, prior to sending it, I will do a Ctrl-a Ctrl-c to copy the message into my Windows Clipboard as a safety measure to avoid losing the message in case my Internet connection or GardenWeb do a "hiccup".

If you upgrade fixtures, ever, strongly consider biting the bullet and looking into a dimmable digital ballast that can handle either HPS or MH bulbs. There's a few new players in the lighting market that intent on driving the prices down into casual grower market, and having started with whole arrays of CFLs and fluorescent tubes that had been re-purposed from product photography into grow lights, and then swapping the whole mess for a SINGLE $150 lighting system that can kick out comparable wattage, and STILL be cranked up another 50%, I can't say enough about the difference. You really can't beat daylight spectrum tubes and CFLs for trays and trays of seedlings and small plants, but once you get them flowering and have committed a guest bedroom, I'm a huge believer in going big cost effectively :)

Incidentally, I haven't done extremely formal measurements, but I do have roughly similar wattages of HPS, Metal Halide, and CFL bulbs, and zinnias seem EXTREMELY sensitive to light color with their internode length. If you don't want them getting out of hand, you'll want bluer light.

My first generation of green seeds are almost to budding!

{{gwi:26452}}

Meanwhile, the random seeds from last year are mostly pinks and light purples that I'm culling out. I've gotten a few interesting and pretty flowers though, that I'm actively crossing with dark purples to see what I can get out of them:

{{gwi:26453}}

These have a yellow stripe that would look better on a darker purple flower that doesn't come through well in the picture.

Hi Mister Guy,

" There's a few new players in the lighting market that intent on driving the prices down into casual grower market ... but once you get them flowering and have committed a guest bedroom, I'm a huge believer in going big cost effectively :) "

I am very interested in what new options might be opening up for indoor gardening under HID lights. Growing zinnias beyond the first bloom stage under fluorescent shoplights is a bit of a challenge for me.

Incidentally, I have partial confirmation regarding your observation that bluer light helps control internodal length. However, your budding seedling looks a bit "stretched". What sort of light has it been getting? Incidentally, it looks very well nourished -- no obvious symptoms of specific nutrient deficiencies.

ZM

I have not heavily researched the company other than reading reviews on Amazon and buying a system, but I have been pleased with my system by Apollo Horticultural. I bought a kit with both bulb types, and a cool tube fixture for 150 on Amazon. I have over extended my own lights, because I have very little self control and have a LOT of plants sharing the light right now. The second round of zinnias got shoved over to the corner until the previous generation gets culled and the sunflowers stop hogging the main light. The room they are in isn't ventilated well, so I turned the lights down for the hot weather we just had. Now of course we get an ice storm....

Hi ZM and MG, can we say overload?! Thanks truly for all the info; I’ll make note of it for later. I’m not anxious to have to replace my present system, but it has been in use for more than 2 decades of garden seasons with me, and no telling how long before that with my friend, so the time may come sooner rather than later.
And to test whether I am using the proper HTML code, here are two pics of my pre-germination set-up. The first one shows the paper towel with pepper seeds before folding, and off to the side the already folded packets.

Well, I see my blockquote attempt didn't make it, though I have succeeded in posting the pics. Excuse my ignorance, but am I actually supposed to put the words blockquote in those arrow brackets?
Whoa - wait a minute...it is indented, but only on the left side. I can see that in comparison with what I'm writng now. What's that about?

This was because of the pics, wasn't it? They're too big maybe. My text after I ended the blockquote is out of bounds, I see. Well, here's the next test: I will attempt blockquote but without the pics.

Success.

Overload is definitely a problem, but it's easy to creep up once you have a couple different full size plants. They seem so small when you plant a 36 cell tray, but 36 adults take up some room ;-) And once you start sliding down the hill, may as well jump right?

MG - Tell me about it! And I do so hate to throw healthy seedlings on to the compost pile. But over the years, and especially within the last 5 or so, I have hardened my heart, and made the cull. However, this hybridizing project will put a whole new wrinkle into the fabric. When I haven't seen the bloom yet, how can I bear to throw away any potential beauties? That's part of the reason why I was questioning so closely about how one knows if it's ones own cross or a self or insect-cross.

Hi Alex,

"When I haven't seen the bloom yet, how can I bear to throw away any potential beauties? That's part of the reason why I was questioning so closely about how one knows if it's ones own cross or a self or insect-cross."

Yes, when you have been cross-pollinating your zinnias yourself, all of your seedlings are potential beauties. Or, in some cases, "beasties". I usually try to get my seedlings to the first bloom phase before I cull them. I usually impose some pretty high standards at the first cull, and I will discard and remove 90% or more at that time, leaving more room for my favorites to develop.

Like I said, if you have been applying pollen to some stigmas and they respond by quickly shriveling away within a day or two, you can be reasonably certain that they were fertilized by you, and not by an insect. I don't resort to isolating my zinnia blooms with "hairnets" even when there are a lot of bees about, because the bees aren't the least bit interested in pollinating any zinnia stigmas. The bees are just after nectar and/or pollen (which is a highly nutritious food for them). I save the hairnets for bird protection of my choicest seeds.

My indoor zinnia project has been successful in producing a nice supply of F2 recombinant seed that I can plant in-ground outdoors this Spring. I am currently making cross-pollinations on my second generation of indoor zinnias, and that feels pretty good. No bees to worry about in here.

Incidentally, I do cull my indoor zinnias, but since they are seed producers of known good crosses, I don't cull them nearly as severely as my outdoor zinnias.

ZM - I may not have a choice but to cull some before bloom, just so I have room for everything else. I've got alot of veggies and some other flowers that will be sharing the space - assuming I do start some of my zinnias indoors in April to give them a headstart.
And on that note, I already have a few eggplant and pepper seeds germinated out of the batch in the pics above - and so it begins! - Alex

Hi Alex,

"I may not have a choice but to cull some before bloom, just so I have room for everything else."

It's OK to cull seed packet seedlings, because you don't have much invested in them. If I have a lot of tomato seed, I plant 4 seeds in each little 3.25-inch square pot and even if all four come up (as is frequently the case) I pluck out the weaker seedlings and save the strongest seedling. Survival of the fittest. And even for my hybrid zinnias, if a seedling is obviously defective, I will cull it.

Last Spring I had a star-tipped mutant in my commercial "white cactus flowered" patch and, because it apparently did have some different genes, I crossed it with a lot of my breeder zinnias. I have shown it before, but this is a picture of the original mutant.

{{gwi:26456}}
Its genes are expressing themselves in many of the crosses involving it. This is a current indoor picture of a cross between it and a tubular petaled breeder.

{{gwi:26457}}
This F1 hybrid isn't spectacular, but I have been saving a significant number of seeds (over a thousand) from such star-tipped F1 hybrids in my indoor gardening project, and I will be looking forward to seeing what the star-tipped genes can do in various F2 recombinations involving them. I had qualms about such a large number of crosses involving a kind of ugly looking mutation, but I am currently encouraged that it was "an ugly duckling" that could turn into "a beautiful swan".

Hello everyone. Glad to see some new people interested in zinnias - welcome aboard!
My own zinnia adventure of 2014 will be beginning soon here in Missouri, and I hope to share some wonderful pictures with everyone over the summer. Previously, I saved all of the seeds from zinnias "that I thought looked good" into a single envelope. I also saved the seeds from the zinnias that I didn't much care for, just for fun. I will be planting a little of everything this year, and I'm really excited at the prospect of getting more zinnias that I will enjoy.

Last year, I direct sowed the zinnias into a raised bed, and that left me waiting well into the summer before I had a single bloom. This year, as soon as my onions have hardened off, there will be room under my light dedicated to a tray of zinnias. These will be headed into the garden at the same time as the tomatoes, and they should bloom around May. After that, when the chance of frost is gone, I'll be starting a lot more in trays outside to be spaced properly in a patch of soil all to their own. This seems to work the best for me, after trying a lot of methods.

I really enjoyed reading everyone's posts over the winter, and glad a lot of you guys are growing them indoors as well. It takes something special to grow a full sun ornamental during the dark months. Maybe we're just a little bit crazy.

I'd already been thinking I should do more succession planting this year; this sounds like maybe a better way to do it than direct seed. I suppose I haven't in the past simply because I reach the psychological point where my fixed goal is to get everything in the ground, then it is: GARDEN. Crazy, I know. It's a mindset. I mean, it's not like the work ends there - on the contrary, the work really kicks in then! But it's such a long nit-picky process up till then: ordering the seeds (or testing the ones saved to see if I need to order any), pre-germinating the seeds, planting them under lights, transplanting, transplanting again, transplanting AGAIN, moving to the greenhouse, hauling trays in and out of the greenhouse during the hardening-off, planting outside, covering everything wildly when frost threatens - which it usually does at least once after I've planted things out. By that time, I'm just wanting to be done with that portion of the process. But I can change. See - I know how to do blockquotes and italics now. Ha!
ZM - looking forward to seeing the new star-tipped mutants.

BTW - my pre-germinated peppers and eggplants are sprouting like crazy after only a few days! That's one of the definite advantages to pre-germination.

Hi Telescody,

" I really enjoyed reading everyone's posts over the winter, and glad a lot of you guys are growing them indoors as well. It takes something special to grow a full sun ornamental during the dark months. Maybe we're just a little bit crazy. "

I think in my case, more than a little. But I am really enjoying the indoor zinnia growing. It really raises your spirit when it is frigid and snowy outdoors to be able to cross-pollinate my very own hybrid zinnias under bright fluorescent lights. And I am excited by the prospects of some of my recent crosses involving mutants. This tubular hybrid shows some star-tipped hints on the tips of its tubular petals.

{{gwi:26458}}
It is basically an F1 hybrid between a tubular specimen and my star-tipped mutant (designated as G13) and although the star-tipped effect is very subtle in this F1 hybrid, I am hoping that recombinations in the F2s from its seeds will result in something more interesting.

We will be looking forward to your zinnia pictures this year. It sounds like you plan to "up your zinnia game" this year. I am hoping you get some interesting zinnias.

Hi Alex,

"I'd already been thinking I should do more succession planting this year; this sounds like maybe a better way to do it than direct seed."

I have never done indoor planting as a substitute for in-ground planting, except for a few high value seeds that I didn't want to subject to the risks of in-ground planting, such as cutworms, moles, etc. There is a lot less labor involved with in-ground planting. No pots to wash, no checking everyday to see that they have enough water, no transplanting to do. In-ground zinnias aren't as "needy" as indoor zinnias.

However, I am a fan of succession planting in-ground. By making succession planting, your zinnias don't all come into bloom at once. By staggering their bloom times, you can give each one more individual care with respect to culling, labeling, cross-pollinating, etc. I have a fairly large garden and I can get swamped with tasks that need to be done if I try to start everything at once.

We are supposed to get some warmish weather next week. I am getting the feeling that Spring isn't far away. I did some cleanup work in the garden a couple of days ago. I removed some dead zinnias from last year and adjusted the height of the hoops on one of my low tunnels.

More later.

ZM,

I did some cleanup work in the garden a couple of days ago.

I can't even get into the garden! There's a heavy pile of snow/ice gluing the gate shut. Can't walk comfortably in there anyway - snow's too deep. But we are experiencing a gradual warm-up, too. Finally.
Meanwhile, the garden light table got fired up for the first time this season over my eggplant and pepper seedlings. :)

Hi Alex,

" I can't even get into the garden! There's a heavy pile of snow/ice gluing the gate shut. "

Clearly you have a much more arctic climate in Michigan than we here in Kansas. The top few inches of our soil have thawed, although it is still hard frozen a few inches down. I am hoping that our soil will thaw some more this week, because there is an area of my garden that has a lot of rocks in it that I want to rake out before planting it. Right now the rake teeth just sort of "bounce off" of that still frozen layer.

Incidentally, you have mastered the "blockquote" thing quite well. There are a couple more HTML things that are easy to use, and handy sometimes. They are "b" for bold and "u" for underline. In these examples, as before, I will use square brackets to indicate the HTML, and let angle brackets, which you don't see, cause the actual execution of the HTML. Sometimes, [b] if you want something to stand out a bit [/b], you can use the "b" command, and [u]if you really want to emphasize something[/u], you can use "u" to underline it. You can [b][u]combine the two[/u][/b] if you want, or [I][b][u]use all three [/u][/b][/I].

There is another HTML command, the "font" command, that is somewhat more complicated, and somewhat more capable. You can use it to [font color="red"] change the color of your text,[/font] but I don't usually have a need for colored text. Incidentally, there are an amazing number of colors at your disposal. I just picked red because it is a simple example. You may or may not have noticed that I used the "font" command to change the typeface of this paragraph, up to this point. I used the [font face="Georgia"] command. Most, perhaps all, browsers let you set a default typeface, and this forum itself probably controls its fonts as well. I sometimes enjoy diddling with details, but I hope the phrase "the Devil is in the details" doesn't apply to me.

Back to the weather, we are having a nice sunshiny day here. I know your weather will improve and sometime this Summer, when I am sweltering in three-digit heat, you will be much more comfortable. More later.

Hi all,

Since this message thread now has over 100 messages, and it is getting a big long and slow to load, I am starting a new part over at It can be fun to breed your own zinnias - Part 24. I look forward to seeing you all over there.
