Discussion

Although some populations are large, Delphinium uliginosum is very local. Hybrids with D. hesperium subsp. pallescens have been seen.

Delphinium uliginosum is a very distinctive species, not likely to be confused with any other. The fan-shaped, slightly dissected leaves are apparently unique in the genus.

Delphinium andesicola, the westernmost representative of the southern Cordilleran complex, is found in the Chiricahua, Huachuca, Graham, and White mountains. Hybrids with Delphinium scopulorum are known.
