This species is listed as endangered species and was thought for a while to be extinct until populations were found in Tennessee. There are hybrid forms offered in the seed trade. More information on this species. Full sun to light shade, easy to over winter. Cut back stems after flowering to encourage more flowers and to prevent self-seeding.
Plants attract bumble bees.
Leaf minors are a nuisance but not a serious problem. Powdery Mildew in hot humid climats or were the summers have been wet and hot. Gray molds occasionally and bacterial spots. The only real insect problems are Vine Weevils, which will feed on the root stock and root aphids. The largest problem is Aster yellows, a virus, which produce stunted plants with grotescly formed flower heads.
