Discussion

Subspecies caurina, the only subspecies that does not occur in California, is found along the coast and along the Columbia River in Oregon and Washington to British Columbia (only on Vancouver Island).

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Subspecies whitneyi is common in cultivation, mostly as hybrid derivatives with other subspecies, but is scarce in the wild, found only rarely along the coast in Humboldt and Mendocino counties; it is listed as rare by the California Native Plant Society.
