Discussion | 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.) |
Hybrids with Delphinium glaucum are known. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
