My most favorite species of Delphinium is D. nudicaule, a native of northern
California and southwestern Oregon. The best form of this species are the
scarlet red flowers with succulent leaves, such as ones found at the top of
Mount Diablo in northern CA. The top of the mountain is just about 4000ft,
and receives snow in winter.  Photos of this form and several other forms
can be seen on the wiki:…

If anyone in colder climates would like to try a summer dry Delphinium that
is hardy, high altitude form of this species would be a charm to have in the
garden. I'm not sure how it responds to being grown in the ground though.
