Discussion

Subspecies 3 (3 in the flora).

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Although some populations are large, Delphinium uliginosum is very local. Hybrids with D. hesperium subsp. pallescens have been seen.

Delphinium uliginosum is a very distinctive species, not likely to be confused with any other. The fan-shaped, slightly dissected leaves are apparently unique in the genus.
