Ceanothus crassifolius is a species of flowering shrub known by the common name hoaryleaf ceanothus. This Ceanothus is found throughout the coastal mountain ranges of the southern half of California below 3,500 ft., and its range extends into Baja California. It is an erect, spreading shrub which can exceed three meters in height. The branches become long and the younger twigs are fuzzy with white or light brown hairs. The small evergreen leaves have widely-spaced teeth along the edges and the undersides are lighter in color and coated with hairs. The flower clusters are borne on short stalks less than three centimeters long and are small and rounded with tiny white flowers. They can be quite dense and can cover branches thickly, or they may be sparse. The flowers may have a yellowish or pink tint. The fruit is a horned capsule less than a centimeter wide. C. crassifolius typically occurs in California chaparral plant associations; other common flora associates are Toyon and Hollyleaf cherry.
