Notes: 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. Small, tan seed heads appear on tall stems held well above the foliage. 24-30 inches. June-July.
