CPoint Reyes Ceanothus (Ceanothus gloriosus) is a species of shrub in the Buckthorn family (Rhamnaceae). It is endemic to California, where it is known from the coastline of the San Francisco Bay Area and areas north and south. It grows on seaside bluffs and the slopes of the coastal mountains.


This shrub grows flat and spreading to erect. Its three recognized wild varieties have different characteristics, and each is considered rare. There are also a few horticultural varieties such as 'Anchor Bay' and 'Mount Vision.'


The evergreen leaves are oppositely arranged, with toothed edges, the teeth sometimes spine-tipped. The flower cluster is a small cluster of bright blue to purple flowers. The fruit is a horned capsule. This plant is highly recommended for coastal gardens where a compact form is desired.
