Tall fescue

Festuca arundinacea

Importance

Found in damp meadows and river banks.  Cultivars are used in forage grass mixtures throughout Europe.  Cultivars are also used in lawn seed mixtures in North America on account of its ability to tolerate warm summers and cool winters.  It produces a coarse textured lawn the most notable of which is the South lawn in front of the White House (Washington).
