About this species

Oat (Avena sativa) is one of a number of species of domesticated and wild oats in the genus Avena (the members of which are collectively known as oats). Oat is descended from A. sterilis, a wild oat that spread as a weed of wheat and barley from the Fertile Crescent (a region spreading from Israel to western Iran) to Europe. It was domesticated about 3,000 years ago, in the wetter, colder conditions of Europe, in which oats thrive, and soon became an important cereal in its own right on the cooler fringes of Europe.
