Discussion

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

Of conservation concern.

In addition to the Alabama sites, Delphinium alabamicum is known from one population in Georgia; it might have been transplanted there. Delphinium alabamicum has not been seen in central Alabama since 1950; populations there might have been extirpated.
