Ceanothus lemmonii is a species of shrub in the buckthorn family Rhamnaceae known by the common name Lemmon's ceanothus. It is endemic to California, where it grows on the wooded slopes of the Inner North Coast Ranges and the Sierra Nevada foothills to the west and east, respectively, of the Sacramento Valley. This is a spreading shrub approaching a meter in height and slightly more in width. The woody parts are gray when aged and new twigs are green, hairy, and sometimes hairy. The evergreen leaves are alternately arranged. Each is oval in shape and dull green, densely hairy on the underside and more thinly hairy on the upper surface, and the edge is lined with tiny hairy teeth. The abundant flower clusters are clusters of pale to bright blue or purple flowers. The fruit is a smooth capsule a few millimeters long.

For propagating by seed: Hot water and 3 mos. stratification. Alternative treatment: boil in water 1 min.; then, instead of stratification, soak in 400 ppm GA, 13 hrs.; air dry 4 days; soak in 3% thiourea 5 mins. Seeds may then be sown or dried again and stored. In this quick treatment gave 48% germination for Ceanothus lemmonii. (Adams et al. 1961).
