section divider
Oat is also known as groats or oatmeal. The blades of this grass family-member are rolled in the bud and are flat at maturity. There are about 25 varieties of this genus cultivated. They commonly grow to about 4 feet. Oat is found over vast geographic areas. Flowers are wind pollinated from late summer to early autumn. Cultivated oats are self-pollinated, so they shed little pollen.
