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.) |
Delphinium umbraculorum is most often confused with D. patens subsp. hepaticoideum; refer to discussion of that taxon for distinguishing features. Hybrids occur with D. parryi and D. patens subsp. montanum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
