A rather large list of bulb and seed sources is at Great Lakes Bulb Society. Type it into your browser and the list shows up. Some 50 or so species and variants of Calochortus are listed by the Archibalds as seeds-- go to http://www.jjaseeds.com/ They were collected about 3 years ago. It is almost a complete range of the genus from northern to southern California. Cheers, Adam
