Coyote Bush, also known as Chaparral Broom or Bush Baccharis, is a shrub that grows in California, Oregon, and Baja California. It is usually smaller than 8 feet in height.
It is known as a secondary pioneer plant in communities such as coastal sage scrub and chaparral. In California grasslands, it comes in late and invades and increases in the absence of fire or grazing. Coyote bush invasion of grasslands is important because it helps the establishment of other coastal sage species.
Coyote bush is common in coastal sage scrub, but it does not regenerate under a closed shrub canopy because seedling growth is poor in the shade. Coast live oak, California bay, or other shade tolerant species replace coastal sage scrub and other coyote bush-dominated areas, particularly when there hasn’t been fire and grazing.
Coyote bush is used infrequently in cultivation since it is very useful for hedges or fence lines and for ground cover. It is drought tolerant and rather deer-proof. It requires watering once a week until established and then about once per month during the first summer. It can mature in one to two years.
