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.

Delphinium scaposum is reportedly used in Navajo and Hopi religous ceremonies, as well as for a wash following childbirth (D. E. Moerman 1986).
