Blue Fescue

Festuca glauca

Also known as Grey Fescue, Silver Fescue

Blue fescue forms neat, bristling domes of needle-fine foliage colored in steely shades of silver, icy blue, and sea green. Native to dry rocky slopes and open montane grasslands of southwestern Europe, it relies on a dense, fibrous root network and narrow rolled blades to conserve moisture through intense heat. In early summer, slender culms rise above the basal tussock to bear delicate, light green to purplish flower spikelets that mature into golden seed heads.

Responsible observation
  • Spring grooming: Comb fingers or a small hand rake through the mound to remove dead winter foliage.
  • Soil check: Look for this grass in gritty, fast-draining substrate since heavy clay causes crown rot.
  • Inspect clump center: Older clumps naturally die out in the middle and require dividing to stay vigorous.
