Arctostaphylos crustacea, commonly known as Brittleleaf Manzanita or Crusty Manzanita, is an evergreen shrub native to the coastal ranges and foothills of California, particularly within chaparral and coastal scrub habitats. It has a moderate growth rate and typically reaches a height of 1-4 feet (0.3-1.2 meters) with a width of 4-8 feet (1.2-2.4 meters). The plant has a distinctive appearance with its reddish-brown bark that often peels in thin sheets, and its small, leathery leaves that can be brittle, hence the common name. Brittleleaf Manzanita produces dense clusters of urn-shaped flowers that are white to pink and bloom in the winter and spring, providing a valuable nectar source for native bees and butterflies during a time when few other plants are in flower.

This species is valued for its drought tolerance, low maintenance requirements, and its ability to thrive in poor, rocky soils. It is often used in native plant gardens, xeriscaping, and as an ornamental in residential landscaping for its attractive bark and flowers. Brittleleaf Manzanita is also appreciated for its wildlife value, as it provides food and habitat for various species. It requires minimal water once established and prefers well-drained sandy or loamy soils. While it tolerates a range of light conditions, from full sun to part shade, it flourishes with more sunlight. There are no major disease problems, but it can be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
