FESCUE

any of about 100 species of grasses constituting the genus Festuca (family Poaceae), native to temperate and cold regions of the Northern Hemisphere. Several species are important pasture and fodder grasses, and a few are used in lawn mixtures. Meadow fescue (F. pratensis; formerly F. elatior), a plant about 0.5 to 1.2 m (1 1/2 to 4 feet) tall, is used for fodder and as a permanent pasture grass. Both meadow fescue and tall or reed fescue (F. arundinacea) are Old World species that have become widespread in parts of North America. The shorter, fine-leaved sheep fescue (F. ovina), often found on mountainsides, grows in dense tufts and forms turfs in dry or sandy soil. One variety, known as blue fescue (F. ovina variety glauca), has smooth, silvery leaves and is planted in ornamental borders. Red fescue (F. rubra) is used in lawn grass mixtures.
