A rarely seen native grass making neat clumps of grey leaves and upright stems of dense spikes of flower in summer to 20cm.  Good drainage in sun, preferring chalky soil.

Koeleria macrantha is one of those unusual British native grasses that can make an attractive addition to the garden and never outstays it's welcome!  Tightly clump forming, it doesn't self-seed either in our experience, but if you collect the seed and sow it in a pot it will germinate.

Best used at the front of a border or on a larger rockery or scree as it's quite small and doesn't appreciate vigorous competition.  It works well grown with other plants from similar conditions such as Pulsatilla and Veronica spicata.

Crested Hair Grass or June Grass, it grows over a wide area in calcareous soils.

Syn. Koeleria cristata.
