I don't see them grown often here either, which is a shame. I'll have to do some looking, it has been 9 years since I moved so I'm not sure where those photos would be at the moment. The yard of my previous home was surrounded by forest and there was a stream running through the front yard. In spring the forest floor was carpeted with erythronium, Dutchman's breeches, and Trillium grandiflorum.
