Baccharis pilularis
  

Zoom To My AddressZoom To California Estimated Plant Range

About Coyote Bush (Baccharis pilularis) Names include Coyote Brush (or Bush), Chaparral Broom, and Bush Baccharis. It is a common shrub in the Asteraceae that grows in California, Oregon, and Baja California. There are two subspecies. Ssp. pilularis is more common along the central coast. Ssp. consanguinea is found all along the coast and inland to the Coast Ranges and the foothills of the Sierras. All forms of this shrub are generally 1-3 meters in height. It is smooth and generally sticky. The stems are prostrate to erect which branches spreading or ascending. The leaves are 8-55 millimeters long with three principal veins and have profuse, white or yellow, rayless flowers that bloom in early winter. They are found in a variety of habitats, from coastal bluffs to oak woodlands.

Coyote Brush is extremely easy to grow in landscape applications. It tolerates summer water up to weekly, but naturalizes easily also. It is said to be fire resistant. The form is highly variable, ranging from upright to mounding to prostrate. Several forms available in native plant nurseries make an excellent groundcover. Named varieties include 'Twin Peaks', 'Santa Ana' and 'Pigeon Point'.
