Discussion

Varieties 2 (2 in the flora).

A common shrub on mountain slopes, Ceanothus velutinus, which reproduces by both seeds and layering, often forms large colonies, especially following fires or forest clearing. The leaves of C. velutinus are strongly aromatic (often vanilla-scented) when crushed, and the adaxial faces, especially in var. laevigatus, appear varnished.

An infusion of leaves of Ceanothus velutinus was used by Native Americans in cleansing and to treat skin inflammations (D. E. Moerman 1998).
