Ceanothus cordulatus, commonly known as Mountain Whitethorn or Snow Bush, is an exceptional native shrub that thrives in high elevations, bringing both beauty and ecological benefits to your landscape. This evergreen marvel is distinguished by its striking white flower clusters and distinctive blue-green leaves nestled on thorny branches. Reaching heights of 3 to 6 feet and spreading up to 8 feet wide, it forms an attractive, dense thicket perfect for erosion control and creating rich habitats for pollinators and wildlife.

Adapted to full or part sun and well-draining soils, Mountain Whitethorn is remarkably hardy to USDA Zone 5 and requires minimal water once established. Its natural range extends through California, Oregon, Nevada, and Baja California, flourishing on mountain ridges and forested areas. The shrub's unique nitrogen-fixing properties make it invaluable in old-growth forests, providing lasting nitrogen patches post-disturbance, such as after forest fires. Its robust, spreading form, coupled with its rarity, makes it an ideal choice for sustainable gardening and land restoration projects. Whether enhancing natural areas or protecting sloped terrains, Ceanothus cordulatus seamlessly integrates charm and function into your outdoor space.
