| The oat (Avena sativa), sometimes called the common oat, is a species of cereal grain grown for its seed, which is known by the same name (usually in the plural, unlike other cereals and pseudocereals). While oats are suitable for human consumption as oatmeal and rolled oats, one of the most common uses is as livestock feed.
Oats are sown in the spring or early summer in colder areas, as soon as the soil can be worked. An early start is crucial to good fields, as oats go dormant in summer heat. In warmer areas, oats are sown in late summer or early fall. Oats are cold-tolerant and are unaffected by late frosts or snow. (Source: Wikipedia)
