Helictotrichon sempervirens 'Blue Oat Grass'
Common Name: Blue Oat Grass, Ornamental Grass
Blue Oat grass looks like a miniature water fountain, with its densely packed leaves gently spraying upward and arching back downward at the tips. This species displays spiky, blue-gray foliage that will draw your attention all season long.
In early summer, small, tan seed heads appear on tall stems held well above the foliage. In mild climates, this grass is evergreen; it is semi-evergreen in colder zones.
Blue Oat Grass adds a wonderful coarse element to rock gardens, coastal gardens, or dry hillsides.
The best place to plant Helictotrichon is a dry, sunny site. Once established, it will not require supplemental watering unless there is a drought. Trim back the old foliage to 3-4" in spring before the new growth emerges. Division is recommended every 3-4 years in spring to keep the plant looking fresh.
