ok well I found this which answered some of my questions, but I still don't know where to buy/get the plant.
or if it will reseed like crazy, I guess just cut the heads off before the seed drops? It does say to watch for mildew on the plants, are there resistant varieties? Most of the hybridized flowers I've tried I didn't like and the old wild ones look better to me. Like daisies and black eyed susans ect.
