Hi Cathy: It is from Tuolumne County, at about 2-3000' elevation in the Sierra Nevada. Your problem is probably that your summers are too hot. Most Erythroniums hate hot summers. Even the ones that come from hot areas grow very deep to escape the heat. In moderate temperatures they can tolerate summer water if drainage is very good. The best Erythronium for a hot region is E. multiscapoideum. Diana Telos Rare Bulbs
