this talk about asclepiads reminded me of a beautiful intriguing bush that i've seen growing in a garden once -- the flowers were blue and very beautiful. i can't recall the name, but i think it's Calotropis.
yes, i just did a search, and it's Calotropis gigantea, although the search also yielded C. procera, which i haven't seen before.
also, aren't asclepiads now in Apocynaceae?
