What is tall fescue?

Tall fescue, or Festuca arundinacea, is a cool-season grass, widely adapted and used in many parts of the world, for both turfgrass (lawns, parks) and forage uses (pastures, hay, grazing). The first US variety was called Kentucky-31, selected and developed in Kentucky around 1931. Since then there have been many improvements, although some people still use Kentucky-31 because it is inexpensive.
