[Cal-IPC] Invasive: Genista monosperma (bridal veil broom) is an escaped ornamental plant in the family Fabaceae. Although it is currently invasive in only one population in San Diego County, Cal-IPC lists it as an alert species due to its invasiveness in other areas with climates similar to California. In six years, this one infestation spread in size from approximately 1 acre (4 ha) to 1980 ac (800 ha). Like Scotch and French brooms, bridal veil broom can produce thousands of seeds per plant that may then be carried long distances by birds. Cal-IPC Rating: Moderate Alert (link added by Mary Ann Machi)
