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.

Delphinium sapellonis hybridizes with D. barbeyi and D. robustum. It replaces D. robustum and represents the southern Cordilleran complex at higher elevations of the southern Sangre de Cristo Mountains east of Santa Fe. It is not known elsewhere.
