Shrub, to 5 feet tall for the cultivar 'Eve Case' normally planted on campus, the species can achieve the stature of a small tree, as seen at Jasper Ridge. The berries rippen in the winter and can be marble-sized, Green to red to black. Once established it performs well without irrigation.

Frangula californica varieties californica and tomentella grow at Stanford University's Jasper Ridge Biological Preserve. More information about Jasper Ridge's flora and plant communities.

Like the leaves of its relative Rhamnus alaternus, the secondary leaf veins are festooned (secondary veins form at least one row of loops or arches outside).
