The white one for me wasn't too aggressive compared to any other perennial. The standard purple one (don't know the variety) is aggressive and have to keep an eye on it. It's loosing the battle with a clumping bamboo though so it can't go too far. Any remnant of the runners that you leave in the ground will start up new plants but the are easy enough to pull.

The white flowered Physostegia virginiana/obedient plant Is probably P. "Miss Manners". I had it for several years in a bed and it did not spread at all. It finally died out after two or 3 years of gradual decline. I liked the plant, but it never had the vigor of it's pink invasive relatives.

I have a similar problem with bindweed growing among my perennails and through some of my low growing evergreens. This is the solution I came up with to apply Roundup - Tear off a piece of aluminum foil, line it with paper towling, curl the foil around the vine part way,stuff as much of the vine as you can into the packet (I liken it to putting a hotdog in a bun), spray the weedkiller inside the little packet, close it up tightly. In day or so you can remove you little foil packet, making sure the foliage has absorbed the spray and is completely dry.

My experience with this plant is that it is more prostrate than trainable. It isn't really noticeable until your bike tire goes flat or you step on it. So it sneaked up on you. It is said to be an annual at your temps, so that means it should be easier than bindweed for you. One thing I would do is make sure that it is exposed all winter so that it really is killed. So really focus on and get out all those plants that are going to be protected by your wanted plantings. I would get a good hoe and use it all spring, learning what the baby plants look like so I can get them all out early before they seed. A good hoe and diligence early on is the safest and cheapest remedy.
I have never had someone using glyphosate near me kill my organic garden, but I have had someone take it out using Trimec which contains 2,4d. It is notorious for drift, so be sure if you use an herbicide you follow directions and read the label and be thoughtful. It is really sad and maybe even frightening to see your peonies turn brown in one day, your tomatoes and squashes all distorted. And Ken, I think plants can be pests. I think herbicides can be pesticides, but not all pesticides are herbicides. You just have to get the pesticide for the job you are trying to do. Read the label even if it is tortuous.

Smart thinking Kevin but I never cut my peony blooms to bring indoors. I want to enjoy my garden, aesthetically, olfactorily (sp?) and visually, actually IN my garden and don't care to bring it inside the house. Can't cite a specific reason but flowers indoors have never held any appeal for me [just a personal choice here, no editorializing intended]. I am impressed with those sturdier support rings and may issue a challenge to my I-love-to solve-garden-problems son to construct something similar for my own use.
Peonies are and always will be valued in my perennial beds no matter how they behave. What's not to love? Gorgeous foliage that's unaffected by pests from early on right through frost, gorgeous, fragrant blooms & little to no maintenance. At most I dump woodstove ashes on them in January each year.


Agreed with all of the above. You can deadhead it by grabbing the spent stems and just pulling it out. This also lets you keep the plant in bounds a bit. If you've got tons of it, you can weed whack the old flowers. Whatever you do, don't feel compelled to baby it. It goes through a bit of an ugly phase post-bloom, but it bounces back fast to be a pleasing mat of soft foliage for the rest of the year. It's one of the few seedy plants that I'll still allow here.


Based on what I hear here I bet it was eaten by rabbits!!!!!! We have regular rabbit visitors... and I see them around the yard and they are not afraid to come right up to the house at all. I wasn't sure how far off the ground rabbits can reach/eat because they seem pretty tiny... so that's why I thought it was deer. I thought it was weird because deer never come this close to the house and I never see them on this side of the house, etc. etc.
I also have another new tickseed zagreb that is eaten to the nub every time it tries to leaf out.... I think that's pretty much done for the year.
But great to know at least. We will look into liquid fence, and give it a little time to see how it bounces back.
Thanks everyone!!

Not long lived is correct. I planted one for the first time last fall. About five months later I forgot and pulled it up as a healthy-growing weed. Two days later I realized what I had done. Another gardening oops for the journal; probably why I don't keep a journal. ;)

This is not a show stopper plant, but it is nice. Tolerant of clay, xeric, useful in a xeriscape where there aren't so many red plants. Supposed to be long blooming if deadheaded. I don't think I would buy one in bloom, but I did buy a rosette last year, and it is blooming now. If it reseeds, that is fine with me. Seems to me no site is clear on the nomenclature, though. All list it as amoena.


I posted this photo on another perennial thread, but it shows the location of 'Wild Swan' in my garden.
Thanks for posting 'GF'. My eyes aren't as good as they used to be...is it blooming in this picture? If so could you post a close-up? If not could you keep us up to date when it does begin to flower?
I *just* planted two very small WSwan this past week and I am not sure how much shade it can take and be successful.
As well I am wondering how large this particular Anemone will get and if it will make it through a zone 5 winter.

Yes, it was in bloom, even though it is very difficult to make out in that photo. The flower stems were wilting regularly while the plant adapts to being in the ground. I am on the road for over a week, so no other photos are available right now.


Thanks Ninamarie. Morinas do ok this far south during cool-to-normal summers, but they seem to never really build up enough strength to get through the hot summers. (I'm in Maryland) Since the last three summers have been very hot (fingers crossed this one will turn out differently...looks promising so far) the plant I had for years finally gave up the ghost last summer. It also doesn't help that rabbits will ignore it for a couple years then randomly mow the whole plant down one night. That happened the year before last, so, between that and a 3rd hot summer, it was just too much for it.



I don't believe GW management allows 'sticky posts' but they do have other features that can achieve the same result. The "My Clippings" option allows you to save threads you feel significant or especially informative, both for your own purposes or to share.
And the search feature works for this purpose too. I can't count the number of times I've tracked down an archived thread I've needed a piece of data from.
And as noted, if it is that useful or valuable a thread, including it into the FAQ's is an excellent idea.


Martha, I do the same thing - have my pinks and purples on one side of the yard and my yellows, oranges, and reds on the other.
I've never been big on red (except for lobelia cardinalis which is an absolutely gorgeous red) and if you had told me five years ago that I'd have orange flowers in my garden I would have told you that you were crazy (well, except for the marigolds in the veggie garden.)
Then came the free nasturtium seeds, and some free cosmos Bright Lights seeds, and then I discovered tithonia, and then saw a Chicago Apache daylily and decided I needed to have a spot in the yard for these hotter colors.
The nice thing about yellow, of course, is that depending on the shade of yellow, it will go in either garden!

I have a whole list of yellow flowers for you, but I've forgotten when many of them bloom. I'm sure most of them will love your sandy soil. They should all be hardy in zone 6. Some of these are specific plant species, while others are specific cultivars. They all bloom yellow though and I plan to acquire them sometime in the future if I don't already have them!
-Verbascum nigrum
-Gentiana lutea
-Lysimachia punctata
-Solidago (goldenrod; most species and cultivars yellow)
-Berlandiera lyrata (smells like chocolate!)
-Echinacea paradoxa (there are also many cultivars, like 'sombrero yellow' for instance)
-Aurinia saxatilis
-Achillea (yarrow; most species and cultivars)
-Coreopsis (most species and cultivars)
-Kirengeshoma palmata (needs lots of shade)
-Hollyhock "Chater's Double yellow" (technically a biennial but reseeds like a perennial)
-Helianthus multiflorus 'Flore pleno'
-Heliopsis helianthoides
-Frittilaria imperialis 'Lutea' (also available in orange)
-Ligularia (most species and cultivars; needs lots of shade)
-Penstemon pinnifolius 'Mersea Yellow'
-Thalictrum Flavum 'Glaucum'
-Daylily 'Stella D'Oro' (I'm sure there are other yellow cultivars but can't think of them at the moment)
I'm sure there are many more that I'm forgetting but this is what I can think of at the moment. I actually didn't mind researching this for you. I was meaning to compile a list of yellow perennials for myself anyways. Hope this helped you out.
P.S.-How is your aglaia odorata doing (you grow this, correct?)?? I got one last year but it has unfortunately died (left it outside for ONE night below freezing by mistake, and that was all it took...).

is she depressed?? (hee hee) sorry, bad joke.
I have sprinkled any spice from the pantry, not peppers, as they could hurt her, but garlic powder, something that doesn't make her want to continue, and had luck, even lemon juice, she will learn, i would think.
good luck!!

I somehow overlooked this post. I currently have very sandy soil. There seems to be a good amount of silt/loam mixed in, but it still drains like a sieve and seems to dry out even the day after heavy rains. Keep in mind that I do water with a hose whenever I think of it and have time, but so far I have had great luck with the following:
Oriental-Trumpet (OT) hybrid lilies--these are exquisite and much more hardy and robust than oriental lilies, although the look is much the same. I planted these bulbs deep, some even with 10-12 inches of soil covering the tops of the bulbs, to help provide good ballast in my sandy soil. Second year stems on many of these are over 6 feet tall and are very thick and sturdy. LOVE them! The Longiflorum-Oriental (LO) lilies are also amazing.
Lilium regale--another exquisitely beautiful lily that thrives in well-drained soil. Also planted these deep. Second year stems are also huge and tall but they are never quite as sturdy as the OTs so may lean a bit in sun or require staking in more shade. But the fragrance and classic beauty are so worth it!
Alliums--all types. Even the giant globe types have returned and doubled in their second year with taller and larger bloom heads than the year before (!).
Echinops
Eryngium
Perovskia
Penstemon 'Dark Towers'
Asters
Callirhoe involucrata
Geranium sanguineum
Sedums

Dominoswrath - I really like 'Sunshine Blue' best of the Caryopteris I grow. The gold foliage contrasts well with other plants liking sharp drainage which tend to have silver, bluish, or green foliage, and the blue flowers look lovely against the gold foliage. It tends to be wider than tall in my garden (about 2-3' wide and about 1 1/2' tall.) My 'Dark Knight' is narrower with silvery foliage and the branches are finer and not as stiff as 'SB'. Both are nice plants, though I prefer 'SB' in my garden.



Lilyfleur, burying hardware cloth all around a garden bed sounds like a lot of work, but it would probably work. You could try putting a rock or brick border around the bed. Voles like to travel through loose soil close to the surface and they don't like rocks or gravelly soil. They will turn in another direction if they encounter rocks.
Not sure if it is foolproof, but so far the voles have never bothered any plants that are in my foundation beds, which are bordered by either a stone pathway or bricks.
Hey rouge, I wonder why your H. Lemon Queen is so well-behaved? My patch is now about 8 feet long and 4-5 feet thick. It was about that big when the voles ate most of it. It spreads into the daylilies and I have to pull a lot of shoots out each year.
I am trying to look on the bright side terrene in that your very large stand must look spectacular in the fall!
I may have underestimated the width of mine....probably closer to 3.5 feet. But it is all together. I have never seen any stray seedlings away from the main clump.
