Blue fescue Festuca glauca, from here.

Belongs within: Pooideae.

Festuca, the fescues, is a genus of grasses found in temperate parts of the world. Many species are commercially significant as grazing or lawn grasses; they are often favoured in revegetation programmes for their ability to establish on bare ground.

Characters (from Lu, Chen & Aiken): Perennials, tufted, shoots extra- or intra-vaginal. Leaf sheath margins usually free, rarely connate, sometimes with auricles; leaf blades folded to conduplicate and filiform, sometimes flat; ligule membranous. Inflorescence an open, contracted or spikelike panicle. Spikelets with 2 to several florets, uppermost floret usually reduced; rachilla usually scabrid, rarely smooth or pubescent; disarticulating above glumes and between florets; glumes usually unequal, herbaceous to scarious, rarely subleathery, lower glume often small, 1-veined, upper glume usually shorter than lowest lemma, 3(–5)-veined; lemmas usually similar in texture to glumes, often subleathery at least with age, usually more or less laterally compressed but not keeled, rounded on back at least toward base, usually 5-veined, veins sometimes prominent, apex acuminate, entire or notched, awned or awnless; palea subequal to lemma, keels scabrid, rarely smooth. Stamens 3. Ovary glabrous or hairy on top. Caryopsis oblong or linear, usually ventrally sulcate, usually free from lemma and palea, hilum long-linear. x = 7.
