Discussion | 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.
