Ribes viburnifolium is native on Santa Catalina Island and in northwestern Baja California. It is commonly cultivated; a population from a planting in San Clemente Canyon, Orange County, persists. Reports of populations in seemingly natural areas in Panama are unconfirmed. The leathery leaves are borne on long shoots, and the entire plant has a spicy, resinous fragrance.
