Discussion | Of conservation concern. Ericameria pinifolia ranges from Ventura County to northern Baja California. It blooms primarily in late summer and fall; it sometimes produces scattered, larger flowering heads in spring. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
