Of conservation concern.

Delphinium parryi subsp. blochmaniae is very local; no other Delphinium is normally found within its limited range. It is easily recognized by its very large sepals and lower petals. The only species with which it might be confused is the large-flowered phase of D. variegatum; the latter has long hairs on proximal petioles vs. long hairs absent in D. parryi subsp. blochmaniae.
