Tall fescue (Festuca arundinacea Schreb.) is the most important cool-season grass in the United States, providing the primary ground cover on some 35 million acres. It is a versatile perennial used to provide pasture and hay for livestock, for various turf purposes, and for erosion control. Commonly referred to as simply "fescue," this widely adapted, persistent grass is seed propagated, tolerant of a wide range of management regimes, and it produces good forage yields. Laboratory nutritive analyses of fescue compare favorably to those of many other cool-season grasses.
