About Point Reyes Ceanothus (Ceanothus gloriosus) 27 Nurseries Carry This Plant Ceanothus gloriosus is a species of shrub in the Buckthorn family (Rhamnaceae) known by the common name Point Reyes ceanothus. 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, approaching two meters in maximum size. There are three recognized wild varieties with different characteristics, and all three are considered rare. There are also a few horticultural varieties such as 'Anchor Bay' and 'Mount Vision'. The evergreen leaves are oppositely arranged and up to 5 centimeters long, rounded to oval in shape. The edges are toothed, the teeth sometimes spine-tipped. The flower cluster is a small cluster of bright blue to purple flowers. The fruit is a horned capsule about 4 millimeters wide. This plant is highly recommended for coastal gardens where a compact form is desired.
