    Native to high mountains from Alaska to the Sierra Nevadas, northern Idaho, and Montana. Per my native nursery owner, these have been severely poached in the wild. If you buy one, be sure there it has a USFS metal tag, which means it was harvested by permit. Extremely slow growing so a good focal point plant that won't get away from you. Good candidate for bonsai.
