Helictotrichon sempervirens is an easy-to-grow, clumping, cool season ornamental grass. It forms a bristly but graceful 2 foot mound of steely-blue foliage that is offset by an additional foot of golden-brown feathery flower stems in midsummer. Drought tolerant, the blue color of Blue Oat Grass is more intense in dryer soil and full sun. Evergreen in mild climates and semi-evergreen for colder regions. Use as a specimen plant in the border and rock garden. Perfect fit for the Modern Design and low maintenance gardens as well.
