Here in St John's Newfoundland this plant flowers in late fall (October- November), when the wind and rain often damage the delicate flowers, but when they do open properly they are worth waiting for. They will open up indoors in a vase and last quite well, but are rather short stemmed. I find them rather slower to increase than most colchicums, but they do so slowly; all mine come from a single corm purchased 15 years ago for $22.50 Canadian - they are not cheap, but probably cheaper than this now.
