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.

Of conservation concern. Delphinium purpusii is not likely to be confused with any other Delphinium in North America. Hybrids with Delphinium hansenii subsp. kernense are known to occur. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
