Oats are annual plants best grown in temperate regions. They tolerate cold winters less well than wheat, rye, or barley; they are harmed by sustained cold below . They have a lower summer heat requirement and greater tolerance of (and need for) rain than the other cereals mentioned, so they are particularly important in areas with cool, wet summers, such as Northwest Europe.
