Hey everyone, I might have found the answer to my question... According to http://illinoiswildflowers.info/prairie/plantx/… "The preference is full sun, rather dry conditions, and soil that is rocky or sandy. This wildflower dislikes competition and prefers barren ground where the ground vegetation is sparse." So this would explain why it failed to establish in my prairie bed.... too much competition. I will try it again in my gravel bed where Opuntia flourishes. :-) Thanks for the feedback! Dennis in Cincinnati
