Planted out last year in the pit run gravel scree I put in on the north side of my driveway, these did very well. Cleaning them up in the middle of October, I found a half dozen congested shoots up as much as 6" on the stems pushing to grow roots, very much like similar growths I used to propagate my Becky Shasta Daisies.
The different clumps vary considerably in size. I suspect that they are displaying typical differences within a batch of seedlings.

Started this plant from seed last year and it has really taken off this year. I planted it mainly for the lovely foliage colour but the flowers are a bonus. It stands about 2' tall and is not floppy at all.
Last year I planted 5 of these in my sunny front yard (Atlanta). They did nothing, no blooms and barely any new leaves. I threatened to yank them out of the ground if they didn't perform well this year. They must have heard me because they have absolutley exploded! Starting in March I saw new leaf growth and by late April they were in full, glorious bloom. Very glad I kept them.

This was one of the first perennials I ever planted, and has performed consistently for each of the 3 years it has been in my garden. I love how the green foliage turns red! An excellent, low-maintenance plant.

Planted in part sun. Does very well. Evergreen in winter here in zone 7. It's unfazed by our heat wave (90+ Fahrenheit daytime), drought, wet feet or humidity. The only problem is that my plants are leaning and will have to be staked.
It's June here and they're already in flower since late May.

Beautiful plant, low maintenance, easy to transplant in spring, and very attractive to hummingbirds when in flower. Planted in mass it provides a nice early flower display and the foliage slowly darkens and reddens over the season to provide continual interest. I find the foliage of volunteers and those grown from seed are slower to redden and appear quite green initially, but darken up over time in my zone 4/5 garden.

This is an extremely durable plant. These have survived two winters potted on my second story garage roof (unheated).
They do equally well in the garden. The more sun they have, the darker the leaves get.

Lovely plant - nice color even when not blooming. Last year, I cut the flower stalks back and said 'hummm - looks like these would root." I cut back each stalk so that I had a piece of stem about 3-4" long with two leaves on top and just stuck these around the garden to see what would happen. Out of about 20, I got 6 plants this year and 2 are blooming. I expect I would have more if I had used root hormone and nice little pots with good black dirt. I'll try the suggestion of using the 'non-blooming side shoots' this year. That has answered very well with the wallflowers.

Gorgeous foliage. Nice contrast to the sedums I have nearby. Already starting to flower (May 04). It's interesting that I have three of these plants and all three are in different stages of growth. I can't seem to figure out what is causing it, either. Must be something in the soil I'm not aware of. They're all in full sun.

Easy-to-grow plant, and cold hardy (at least this far north.) It's almost treasonous to grow this plant (named for the Nebraska Cornhuskers) within the geographic confines of the Southeastern Conference, but what can I say?
