Helictotrichon sempervirens is a cool-season grass with a dense, mounded, clumping habit and featuring arching, blue-gray blades. It is non-spreading: clumps slowly grow outward and it rarely self-seeds. Uses include as a focal point, mass plantings, borders, edging. Excellent in seacoast and intermountain landscapes and tolerant of desert conditions if given some protection. It may become summer dormant or grow slowly in hot summer heat. Medium water needs when installed and acclimating; low water use when established. It prefers to stay dry during summer periods. Thrives in average, lean, and sharply well-drained soils. It prefers neutral to alkaline pH and struggles or suffers from crown rot in wet, heavy, clay, or waterlogged soils. Thrives in full sun, but it is tolerant of light or filtered afternoon shade. Best leaf color is in full sun. Fire-resistant when maintained. Deer and rabbit-resistant. Resistant to Verticillium Wilt. Cold hardy to -30°F.
