Acacia melanoxylon (black acacia) is a tree (family Fabaceae) found along the coast of California, in the North and South Coast Ranges, and the San Francisco Bay region. It favors disturbed areas, and is often found near buildings and agricultural sites. Black acacia, which has spherical cream-colored flowers, was introduced as a landscape ornamental and has escaped cultivation in some areas. Black acacia trees can develop root suckers that grow to become large clonal populations. The trees also reproduce using seeds that are dispersed by water movement and human activities. To control mature trees, most root fragments must be removed to prevent resprouting.
