I don't see no seed ;oP

I've never seen it in catalogs before, although I haven't looked specifically for it, either. I think I know where some grows around here (obviously a weedy non-native), but it's been months since it bloomed and died away in the heat of summer.

if you see seed, can you send some to me?

We'll have to plan for next year, then. The plants are long gone and the seed must be embedded in the soil by now. I'd be happy to try sending you some seeds. Weedy though they are, they do provide lovely washes of white and pale blue (as the flowers change color) for weeks in the spring.
