About
Avena sativa is an annual grass cultivated mainly for its grains or as a cover crop. This plant exhibits a vertical, clumped growth pattern, featuring slender stems that support airy, open clusters of oat seeds. It generally attains a height ranging from 60 cm to 1.5 m. The leaves are narrow and linear, displaying a green to bluish-green hue, with lengths between 20 and 40 cm and widths up to 1.5 cm, characterized by a slightly rough surface. During late spring to early summer (May–July), it produces small flowers that transition from pale green to golden, arranged in loose, drooping clusters. These flowers ultimately develop into the familiar oat grains. As the growing season concludes, the plant turns a golden yellow before it dies back.
