Koeleria glauca - Blue Hair Grass

Blue Hair grass is an ideal border plant, non-invasive and attractive as an accent or along an edge. In hot dry conditions, ample water and light shade bring out the best in this grass, but it will tolerate the exposed condition of a rock garden. This grass likes lean, sandy soil and will not look its best when grown in rich soil.

Blue Hair grass has fantastic foliage and nice flowers, which are excellent in dried flower arrangements.
