Regarding the geophytic delphiniums mentioned by Mary Sue and Lee, I was surprised to find that Delphinium luteum, one of those mentioned, can survive outdoors here in northwestern Oregon in a rather nasty winter, at least as young plants. I have this delphinium in my bulb frame, where it seeds about in spite of all my efforts to collect the seed (it is endangered in the wild). Last year I used a lot of discarded potting soil in a rebuilt portion of my rock garden, and many seedlings of this came up in it and grew through a winter that featured 17 F low temperatures without snow cover and an abnormally high rainfall, even for here. One plant, which I must have transferred as a substantial dormant root, is even flowering. Jane McGary
