Discussion | 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.) |
Delphinium multiplex hybridizes with D. glaucum and D. distichum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
