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.
