Calamagrostis foliosa is a cool-season, clump-forming California native grass found naturally on coastal bluffs, cliffs, and other open rocky places in coastal Mendocino and Humboldt counties. The glaucous, bluish-green dense foliage forms low mounds. In spring, narrow, purplish feather-like blooms appear on short arching stalks, generally 15 inches tall, maturing to a tawny beige in summer. Mendocino Reed Grass prefers partial shade but will grow in full sun with adequate moisture. Best in coastal gardens.
