Discussion | Ceanothus parryi occurs in the outer coast ranges of Oregon (Benton and Lane counties) and from Humboldt County south to Napa County in California; it is reported to hybridize with C. foliosus, C. incanus, and C. thyrsiflorus (H. McMinn 1944). The deep blue sepals and petals, cobwebby indumentum on young leaves, and narrowly revolute leaf margins are diagnostic.
