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 scaposum is reportedly used in Navajo and Hopi religous ceremonies, as well as for a wash following childbirth (D. E. Moerman 1986). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
