|discussion=<p><i>Avena sativa</i>, a native of Eurasia, is widely cultivated in cool, temperate regions of the world, including North America. Fall-sown oats are planted in the Pacific and southern states in the United States; spring-sown oats are more important elsewhere in North America. It is sometimes planted as a fast-growing soil stabilizer along roadsides. Several forms are grown, of which the most distinctive are 'naked oats'. These differ from typical forms as indicated in the description, and in having caryopses that fall from the florets. Escapes from cultivation are common but rarely persist.</p><!--
--><p><i>Avena sativa</i> hybridizes readily with <i>A. fatua</i>, forming hybrids with the fatua-type. lodicule. The hybrids are easily confused with fatuoid forms of <i>A. sativa</i>, which differ in having the sativa-type lodicule.</p>
