It is found in the south coast ranges of California. It is native to Eurasia and Africa. It favors grasslands and scrub and chaparral habitat. It reproduces by seed. Animals, wind and water may disperse this plant short distances. It spreads more rapidly along roads than away from roads suggesting seeds are dispersed by vehicles.
