Variety laevigatus is distributed primarily in coastal mountains from California north to British Columbia and on the west slope of the Cascade Range. Ceanothus velutinus var. hookeri M. C. Johnston, based on C. laevigatus Hooker, is an illegitimate name. Putative hybrids between C. velutinus var. velutinus and C. thyrsiflorus have been named C. ×mendocinensis McMinn.
