Lolium arundinaceum

Lolium arundinaceum, commonly known as tall fescue, is a cool-season, perennial C3 grass species native to Europe and introduced to North America and other parts of the world. It naturally occurs in grasslands and coastal marshes. Tall fescue is grown in a range of cultivars, widely used for livestock forage, in lawns and recreational areas as turf, and occasionally for managing soil erosion. Most publications have used the names Festuca arundinacea or, more recently, Schedonorus arundinaceus for this species, but DNA studies appear to have settled a long debate that it should be included within the genus Lolium instead....read more on Wikipedia.
