So today, I just found out about R. bracteata and it was apparently native to my country. (I'm gonna look for it everywhere here whenever I go out of town from now on!)

My question now is...
Any recommendations on Hybrid Bracteatas?
Also, would R. bracteata be good for breeding?

Many food plants aren't easily available anymore not so much due to their genetic instability as to their lack of being financially profitable. The only way to make a plant type economically worthwhile is to possess a patent on it. Once that patent expires, you need others to take its place to continue the cash stream.

Often, older varieties are less resistant to disease and/or insect infections which may not have been issues when they were widely grown. Here in the west, we have Pierce's Disease, which was discovered near Anaheim in 1892 on grapes. It wasn't a huge threat until Glassy Winged Sharp Shooters, native to the South Eastern US were discovered to have made it across country in 1996. We had older varieties of grapes which could still be grown for a century until the wide spread pest began spreading the fatal disease throughout the susceptible types. We now have fatal diseases in citrus due to the same reason...foreign pests spreading them. Look at what is happening to Oleanders here in California. They were the perfect "weed"...toxic so NOTHING ate them; able to endure rather deep cold and blistering heat; able to exist on relatively little water; requiring virtually nothing to thrive and provide many months of unending color...until Oleander Leaf Scorch arrived, also spread by Glassy Winged Sharp Shooters. It's the Oleander strain of the same bacteria which causes Pierce's Disease, spread by the same insect. There was 12' - 15' tall, 50' long hedge of Oleanders out behind this house from the late fifties until four years ago. They existed on only rainfall and provided an excellent wind and privacy barrier. Over the period of four years, they flat out died from the Leaf Scorch. Oleander hedges all over the valley show the effects of the disease. Some nurseries aren't selling Oleanders any more due to the disease.

Many older fruit and vegetable varieties are much less resistant to bacterial and fungal attacks making them more costly and difficult to raise or even maintain. "Resistant" is a huge marketing word when advertising any plant type. Unless you are insistent upon getting the exact older type you desire, most purchasers opt for "resistant" to diseases and pests over heirloom fruit, particularly when the less resistant cost more because they are more expensive to maintain and produce.

Some aren't kept around because of greater cultural requirements or greater space requirements. For rose standards, IXL was the trunk stock of choice for many decades because it generates tremendous growth of very thick canes very quickly, but it also requires significantly greater room to grow mother plants and is much more susceptible to sun scald than Dr. Huey. IXL makes a better standard in less time, but Huey is the standard stock in use now because it requires less room to produce and is cheaper due to less sun scald loss.

Some are being lost due to climate change. Sweet cherries are now not as successful in the more southern orchards because of insufficient winter chill and too great summer heat, as well as insufficient rainfall. If the heat continues pressing northward, it's entirely possible the high chill requiring types may be lost in favor of less winter chill types because there won't BE orchards with enough cold. Plants and animals are already moving north, taking advantage of the milder conditions where the more extremes used to prevent them success. Kim

In addition to losing ancient foundation stock & seeds in plants, it's a concern with livestock, too. England & Europe have scores of breeds of chickens, cattle, sheep & pigs adapted for small homesteads or severely restricted environments. The Rare Breeds Conservatory tries to preserve these treasures from extinction.

The book RARE BREEDS is a gorgeous picture book of some wonderful representatives of old livestock. There is a Scottish sheep that lives on SEAWEED most of the year, White Park cows that were familiar to the Romans, maybe even the Druids, four-horned Jacob sheep, etc. . Africa & India are also reservoirs of some incredible cattle breeds--gigantic-horned Watusi cows, many races of Zebus ranging from milk breeds to draft animals (In the U.S. we simply call all humped cattle "Brahmas"--the rest of the world recognizes they have distinct races--Nelore, Indu-Brazil, Gyr, etc.)

Sorry for the tangent, but the effort to preserve the precious genetic heritage of endangered roses & livestock (not just the more publicized preservation of wildlife & food crops) is really interesting (at least to me!)

As J. L. Hudson puts it: "Preservation through dissemination"

Maigold looks gorgeous but probably won't grow in my region.

I'm thinking about Quadra because it's such a vigorous climber and I want something cane-hardy so that it will get big enough to cover the house.

What I really want to know is weather or not this is a reasonable possibility. Most nurseries list it (and pretty much all other climbers) as topping out around 12'. Is this true? I've seen several pictures of Quadra that look like it's growing much higher.

Rogue Valley has the precise one you seek, but not propagated right now. From their web site: Kim

This is a recent rediscovery in an abandoned garden on Alcatraz Island by Gregg Lowery and Phillip Robinson. The plant that we have is still quite young but already is showing the characteristics that they site: vigorous, floriferous, fragrant. The blooms are almost black red.

FJ,

I live in MS. I tend to gravitate toward own root. How will it differ if it is grafted rather than own root?

My YP (grafted) never thrived either. Pained me to shovel it as the occasional flowers were really exceptional, and I'm a sucker for frilly petals.

Peter Mayle lasted longer and was a beast before mildew finally took it's toll. I would say the flowers look nothing like YP, but there were beautiful in their own right, especially in size, 'bout as big as a grapefruit.

Thanks, Kim.

I'm in Torrance, where it doesn't get terribly hot, and I usually get a SMALL bit of a sea breeze and overcast. The sun isn't all that intense this week, but we've already had a couple of mild hot spells.

My main concern is the health of the plants - I can wait 'til next "winter" to make 'em pretty, if that's the healthiest option.

As a newbie, I see all this literature about when an how to prune, but not much about what is done for the health of the plant vs. what is done for aesthetic reasons.

I read about stripping leaves to force dormancy, but I gather that should be done in January, not March.

I do need to cut back a bit, they're encroaching the public sidewalks.

You're welcome Ed. And, welcome! Torrance is mild enough for you to be able to prune what's needed and not have major issues. I'd go lightly, not removing more than about a third of the foliage and cane mass until you get to know the individual plants and how they respond. Some explode right back into growth after pruning. Others begrudgingly offer a few measly inches. Once you know what their responses will be, you know how to attack them. For growth encroaching upon the walks and doors, that falls into the "you do what you have to do" area. Public (and YOUR) safety take precedence. A good friend lives just down the hill from South Coast Botanical and she has just finished her pruning, so your timing isn't far off. I'll be at her home helping her plant her pot ghetto this weekend. Kim

There are several roses named Valerie but as far as I can see none of them are available for sale.

The plant called "Rose of Sharon" is not a rose, but a species of Hibiscus (H. syriacus). While there will likely be people on this forum who are familiar with Hibiscus, your best bet is to ask on the actual Hibiscus forum. I'm putting a link to it below. Good luck!

Karla, "Althea" or Rose of Sharon, is an extremely hardy, persistent plant. They root EXTREMELY easily in water and (at least in my climate) can be dug, pruned and transplanted as long as they are still dormant (without leaves). They can be severely pruned and will explode back into growth and flower as much bushier plants. If you're in an area still experiencing severe winter weather, wait until your extremes are over and prune them after your chance of last frost. At that time, you can probably transplant them easily and safely. Just keep them watered if you aren't having rains. Good luck and have fun with them. They're great plants! Kim

I love Steve Singer's roses, but I only recommend Wisconsin Roses for rose growers with a little more experience (and a lot of patience). Although Steve's instructions are clear, I think that a newbie might be a little overwhelmed. Steve sells newly-budded maiden roses, and require a little more work to get them started. But, you're right, if someone wants great hybrid teas (Steve has some minis and floribundas too), and you can grow on R. multiflora rootstock, then check out Wisconsin Roses.

Ken I have ordered from Steve and his roses are WONDERFUL! Plus, I get a kick out of cutting the top off the multiflora plant! :) I mainly grow OGRs, ployanthas, and hybrid musks and Steve generally sells exibition type roses. I would LOVE it if another US seller, or Steve, would offer more varieties with multiflora rootstock. Maybe someone will catch on that theres a need for it since it seems the Canadian sellers are having issues importing.

A friend sent that today, via FB, and asked, had I done it. I replied that I had not -- but that I read Liz Druitt's account of trying to do it some years ago, and why she failed. Here's my reply:

(Therein hangs a tale, of course.)

It really is, apparently, true that roses were started in that manner, and carried across North America in pioneer wagons. Probably, some brought them along that way, coming to CA by sea.

Rosarian and author, Liz Druitt, decided to give it a try.
She got some potatoes, did some cuttings, and put the cuttings into the potatoes. They all promptly died.
Tried it again.
They all died.
So, she began asking questions.

The reason it worked for the pioneers is that in them there days, you went out to the garden and dug up a potato. OR you bought one from a greengrocer, who got them from a reasonably local farmer.

The reason it didn't work for her is that potatoes, now, are dipped in chemicals to retard root growth. (Which cost both cooks and grocers a lot of money.)

The chemicals work. They prevent the potato from rooting, and they prevent any cuttings shoved into the potato from rooting.

It would probably work just fine, if you had un-treated potatoes. Organic potatoes.
But what the heck -- we have advantages today that the folks in 1850 didn't have. You can buy really good growth hormones to encourage roots. You can get some nifty seaweed compounds that encourage plant growth. And you can chop up willow twigs to make a tea that will stimulate growth (which folks have been doing for a thousand or so years). You can get good potting soils, and you can make a "cloche" (think, teeny greenhouse) out of a plastic soda pop bottle.

Who needs potatoes? ;-)

A friend suggested that I could grow my own potatoes for the purpose. But, given the success we have with other methods, I replied that if I went to the trouble of growing potatoes, I would EAT them.

I don't see any problems with this, Peachy -- unless you visualize unanimity of size of mature plants.

Great! I was thinking the order would come from the shape of the garden as well as uniform companions, and then the roses could be more wild and varied.

My Lemon Spice has been growing in a pot for about two years, it's got a few canes that are a few feet long. I think it will be fine, if the Marchesa blocks the view I'll just have to cut the Lemon Spice flowers and bring them inside to enjoy.

Thanks for the help!

One inch of cover is plenty for NJ and will not discourage own-rooting (if the plant wants to do it). Don't bully your plants. Own-root is not good for many roses, including probably a majority of hybrid teas. Roses will survive very deep planting, but the reduced oxygenation can incapacitate the rootstock roots and slow the plant's development somewhat.

I've dug deep-planted roses that had no own-rooting, but all the feeder roots developed from the rootstock shank, while the fleshy rootstock roots had not grown at all. This was in a location with adequate drainage.

1" - 3" is fine for my part of NJ (Monmouth Cty.). 6" is too deep (in my opinion).

It looks great! The tomato cage is a good idea and will prevent you from accidentally damaging the rose as it grows up.

Tomato cage is a good idea.

Planting directly into the ground never worked for us. We have weeds, dogs, gophers, and general chaos. But your plants are quite well-grown, so if your area is controlled and civilised, with no dogs running amok, you may be fine.

The Forvo site was a great success with granddaughter as her French textbook doesn't have the phonetic alphabet my old books had. We've been practising words like juillet (she) and Roseraie de l'Haÿ (me).

Marvelous, Kitty! Congratulations! I'm glad, but it's not really "my" technique. It's what has been suggested for bare root planting for many decades. It's "heeling the plant in", keeping it cool, damp and moist so it doesn't dry out until it has a chance to develop roots and grow. Warm and bright pushes leaf, cane and flower production. Cool, damp and dark stimulates root growth instead of top growth. It only made sense to encourage them to do what was desired, that was the way to go! I'm glad it's done what it was supposed to with your Reine Victoria. Nature is pretty amazing (and logical) isn't she? Kim

Cuttings turning brown instead of callusing appears to me to be either insufficient stored nutrients and/or too wet paper. Fuzzy mold sounds like too wet paper. Once they've begun turning brown, they're toast. Good callus and root with a bit of fuzz at the upper end, as long as it doesn't involve all the growth buds, can often be cut off after they are potted and doesn't always grow back as long as the surrounding air is dry enough. If the whole cutting is fuzzy, don't fret with it, just dump it and try another. Kim
