I too am having my first flowering of C purpurascens this summer. Mine are fourth year seedlings, growing in a spot that only gets direct sun at mid-morning. They don't actually ever go completely dormant, as long as I remember to give them a bit of water occasionally. I followed the thread of advice that said plant them deeply, so that the tubers are between 2 and 3 inches down. The fragrance from the flowers is strong and rich, reminiscent of lilacs. I am very pleased!! Dave Brastow 7A - Tumwater, Washington.
