Rita, I'll bet Aster pilosus is the plant at Dunbar, but I'll have to go back and look at photos from that trip. There is another called Calico Aster which has fewer petals, 9 - 14 according to TNPS guide. Judging by the profusion of small white asters now I would hesitate to encourage them in the yard, maybe around the back edge. They do seem to need full sun.

There are always skippers all over it. I wonder if this takes over in the garden. Has anyone tried it? On another note, I have been compiling Cabbage White host plant notes for the book. I never knew there were so many mustards in TN! Rita Venable, Franklin, TN Williamson Co.
