Oat (Avena sativa) is an annual cereal grass grown mainly for its seed (oatmeal, rolled oats) and for fodder. It grows best in cool, moist temperate conditions and tolerates poor, acidic soils better than most cereals.

About
The oat (Avena sativa), sometimes called the common oat, is a species of cereal grass (Avena) grown for fodder and for its seed, which is known by the same name (usually in the plural). Oats appear to have been domesticated as a secondary crop, as their seeds resembled those of other cereals closely enough for them to be included by early cultivators. Oats tolerate cold winters less well than cereals such as wheat, barley, and rye, but need less summer heat and more rain, making them important in areas such as Northwest Europe that have cool, wet summers. They can tolerate low-nutrient and acid soils. Oats grow thickly and vigorously, allowing them to outcompete many weeds, and compared to other cereals are relatively free from diseases.
Oats are used for human consumption as oatmeal, including as steel cut oats or rolled oats.
