Tall native perennial. Throughout spring and early summer, it keeps a low profile as a tidy rosette of dark-green leaves. Then in late summer, its tall flowerstalks shoot up, and finally display their clusters of purple starry flowers. Our single plant lives in the rich new soil of our Lane garden, which may explain why it chose to flop after a storm this year. If it does so again next year, we may have to stake it - not my favorite chore, but this one looks like it's worth it!
Update - it didn't flop as much this year, instead towering over most of its garden neighbors, contrasting against the bright summer sky.

appear in my more orderly beds, I cut them back in June and they
become more bushy, not so tall, more floriferous, and a little later
blooming; |
- Seed from '02 AHS exchange. Baggy 70F (6w) - 35F (7w) - 70F (1w; 0%G)
- Same seed, outdoor treatment. One seedling by late spring
- Seed from '04 garden. Baggy 35F (12w) - 70F (4w; 4%G, 7d)
- Seed from '06 garden. Baggy 35F (13w) - 70F (4w; no G)
So far, consistently low germination. The seeds are variable in size and bulk - perhaps only the fattest ones are viable.
