Darm Crook lives in Hay River, Northwest Territories, Canada. He grows many, many different species lilies. He does grow some of them in a greenhouse, though. I get the idea that with a lot of his lilies that he grows outside, they don't always bloom every year due to the short growing season. (He is colder than you!) They sometimes need a year or more to build up reserves between flowering years. I do know for sure that Lilium michiganense and Lilium canadense bloom every year for him. In season, he regularly posts on the Yahoo Lilium Group:
