Discussion | Subspecies 5 (5 in the flora). A number of local phases are found in Delphinium parryi. Five of these appear consistently distinct and are recognized here. Other phases may be locally distinct but grade into other nearby phases. Delphinium parryi hybridizes with D. cardinale (D. ×inflexum Davidson). The Kawaiisu used the ground root of Delphinium parryi medicinally as a salve for swollen limbs (D. E. Moerman 1986, no subspecies specified).

Delphinium trolliifolium occurs in the northern Coast Range of California, the Columbia River Valley to just east of Mt. Hood, and the Willamette Valley of Oregon upstream to Lane County. California plants differ somewhat from Oregon plants in pubescence patterns and habitat preferences. Further study may show that two entities are involved here. Hybrids between Delphinium trolliifolium and D. decorum, D. menziesii subsp. pallidum (D. ×pavonaceum Ewan, Peacock larkspur), D. nudicaule, D. nuttallianum, and D. nuttallii are known. Delphinium trolliifolium is likely to be confused only with D. bakeri. Refer to discussion under that species for differences.
