Helictotrichon sempervirens is one of the most striking of the ornamental grasses. It produces many stiff, more or less erect stems, growing about 2 feet tall, from a narrow base. The similarly rigid, narrow leaves are held nearly erect. Both leaves and stems are colored a bright blue-grey. Slender wands of rather unexciting pale flower heads are borne well above the leaves in summer. Sun or light shade, well drained soil, moderate to occasional watering.
