Tulipa montana, mentioned by Bob Nold, does appear to be "walking" in a raised bed here. At least, I think it is T. montana -- it was one of the "sp." seed collections from western Iran sold by the Archibalds some years ago. The seed collections of Kurt Vickery and his colleagues include many from wild Tulipa populations. They seem so far to be easy to grow on, and I'm going to have a raised bed built to accommodate them and some alpines. Am still pondering about whether to cover it in winter, but perhaps adequate drainage will allow the plants to survive even a Portland rainy winter.
