I grow my plants year round in my unheated green house. They bloom reliably at different times in winter-spring. They don't always lose their leaves, but I do try to withhold water for periods of time to stimulate blooming. I've mentioned on this list numerous times that even though I have grown from seed selections that were labeled P. dubia, P. carmioli, and P. cinerea, they all look the same to me. Even the ones that have a tiny band of yellow don't keep it as they mature. So I appreciated Dylan's comment that they all look similar in appearance. In the past I have taken pictures to compare these different plants and pictures of the seed pods and seeds and never quite got them to the wiki so I have added the pictures this morning along with a picture from our wiki virus page of a virused leaf. Information about cultivation from Diana Chapman is on this page. http://pacificbulbsociety.org/pbswiki/index.php/… Mary Sue
