(Ceanothus jepsonii)
Ceanothus jepsonii is a species of shrub in the family Rhamnaceae known by the common names musk brush and Jepson ceanothus. This species of shrub is variable, particularly across its two varieties: Ceanothus jepsonii var. jepsonii is a spreading plant growing up to about half a meter tall. It bears inflorescences of blue or purple flowers and spherical fruits. Ceanothus jepsonii var. albiflorus is a white-flowered variety approaching a meter in maximum height. Its fruits are more oblong. Both varieties have firm, toothed evergreen leaves oppositely arranged, curved, often spiny (holly-like), and with their edges turned under. The flowers tend to have a musky odor. It is endemic to California, where it grows in dry, shrubby habitat in the San Francisco Bay Area and the Coast Ranges to the north, often on serpentine soils.
