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.) |
Of conservation concern. Ericameria fasciculata is known only from near Monterey and Carmel bays (Monterey County). It probably hybridizes with E. ericoides. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
