Delphinium

I don't know just John INgram found in southern California, but there are
quite a number of Delphinium species in both the American West and the dry
parts of western Asia that can be considered geophytes. They have tuberous
rootstocks. Delphinium nudicaule, which John mentioned, is one of them. I
also grow D. luteum, a California species with clear yellow flowers, in the
bulb frame, where it seeds like mad, being a typical threatened species; I
send seed to the exchanges from it. I've tried some others but was not
pleased enough with their flowers to use the frame space for them, and most
don't like the winters here. I find D. luteum much more reliable than the
other yellow one that is sometimes grown, the Asian D. zalil (or possibly
that name has been changed).
