Blue Oat Grass provides semi-evergreen ground cover that's especially attractive when planted en masse. This ornamental grass is a reliably beautiful focal point with silvery-blue blades that gracefully arch and sway. It's a charming specimen that sprouts airy, ochre-colored panicles that tower feet above the foliage to deliver natural contrast. It's considered the ultimate specimen of medium sized, blue-leaved grasses. Blue Oat Grass, botanical name Helictotrichon sempervirens, is suited to USDA zones 4-9, with full sun. It reaches a height and spread of 2 ft. to 3 ft. The foliage is a light, silvery blue-green color, with tan colored panicles and blooms. As the best of its kind, Blue Oat Grass is a charming, graceful addition that combines well with any landscape. Add this to your landscape for a dynamic and colorful accent.
