Koeleria glauca (Blue Hair Grass)
Attractive blue-green foliage in neat, weed supressing tufts. Small decorative silvery-green flower spikes appear in summer and mature to straw yellow, they make excellent material for dried flower arrangements.
Koeleria glauca is a useful little grass, ideal for softening the edge of paths or to fill spaces closer to the front of beds and borders where its foliage will contrast well with other grasses. They go well with many perennials and fit well in gravel beds and rockeries. Also effective in planted containers, especially with other grasses of differing form and colour. Larger groups can make effective and colourful ground cover for a sunny area.
Blue Hair Grass is easy to grow, these undemanding plants prefer well drained soil where they will thrive in sun or partial shade.

Koeleria glauca is a semi evergreen grass, the old foliage should be left over the Winter as this will protect the crown of the plant from inclement weather conditions and will still provide structure and interest, especially on frosty days. Cut them back close to the ground in February or March before the new foliage emerges. The cut stems and foliage is useful as a natural mulch or may be composted.
In milder Winters the blue-green will persist all year.
