Found only in the area of the Hearst Ranch on the central California coast, this is quite different than most ceanothus in habit--it lies absolutely flat on the ground, spreading symmetrically to a diameter of 6 feet or more. The leaves are dark green, narrow and somewhat puckered in surface, with a resinous fragrance. It is one of the neatest of the ceanothus for ground cover, though possibly not tolerant of much summer heat (results have been mixed).
