Of conservation concern.
Delphinium parryi subsp. purpureum may be imperiled by human encroachment.
This taxon may be confused with Delphinium parishii, but its abundant arched hairs and lack of wider-lobed basal leaves will distinguish D. parryi subsp. purpureum. It hybridizes with D. parishii subsp. pallidum.
