Helictotrichon sempervirens is a striking, clump-forming ornamental grass known for its dense, porcupine-like mounds of narrow, steel-blue foliage. This cool-season bunchgrass typically reaches heights of two to three feet, featuring gracefully arching blades that maintain their color year-round in mild climates. It thrives in full sun and well-drained soils, exhibiting excellent drought and salt tolerance. Ideal for rock gardens or borders, it produces straw-colored flower panicles in summer.
