I have Chocolate that gets only morning sun and it's about a foot and a half tall, has barely increased in size and still is only in bud. In sun, it gets at least three feet tall and clumps get noticably bigger each year. It has never seeded in the many years it's been in the ground, perhaps that's only because it does bloom so late then gets cut down before it has a chance. Although many years it never got cut down till Spring. The foliage on this plant stays reliably pristine throughout the season (mentioned before). I use it in bouquets as a filler with a little Miscanthus thrown in and it lasts well! That is, when I cut flowers...a rarity! What about a daylily? They're tough as nails and some have especially tall bloom stems. I found one earlier this Summer in one of my borders that was obscured behind an evergreen in the shade and it was blooming its heart out--a deep purplish red with a yellow throat! I divided and moved it front and center in my newly deepened beds. Hoping you find a solution! This post was edited by catkin on Sat, Sep 27, 14 at 15:27

My original Eupatorium Chocolate (bought about 5 years ago) has never made a single seedling. Not sure why. However, I received a couple seedlings at a swap, and the color is very good on these seedlings. One of the swap plants made a seedling last year, where the color is much more dull (still pretty though). Once you collect your seed, you will probably have a lot of sprouts and be able to select the seedlings that have the best color. I have started the species (Eupatorium rugosum) from seed, which is growing in the back in a woodland area (this species will tolerate dry shade, and are deer-resistent). While the foliage is a regular green color, they start blooming much earlier than 'Chocolate' and I think they're pretty because they make these hazy clouds of little white flowers that decorate the background.

Well I must have an unusual specimen because mine is in full sun, with soil that is sandy loam and very well-drained. I don't water it any more than anything else. I have never noticed that it is droopy or wilting. I have also never gotten ONE seedling! I am jealous of all these posters getting seedlings because I would love to have one or two more of these plants. Mayalena I think you even offered me a seedling at last year's swap, which I didn't take and now I regret it! :) I also love the cloud of white flowers which attract zillions of pollinators late in the season. So odd that we have such different experiences with the same plant sometimes!
