Synonyms: Sinapis nigra (L.)
Common names: black mustard
Brassica nigra (black mustard) is a winter annual herb/forb (family Brassicaceae). Like other mustards, black mustard grows profusely and produces allelopathic chemicals that prevent germination of native plants. The spread of black mustard can increase the frequency of fires in chaparral and coastal sage scrub, changing these habitats to annual grassland.Cal-IPC Rating: Moderate
