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 prefers lean 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.
