DESCRIPTION:
Wild oat, a winter annual, has seedlings with hairy foliage, like hare barley. However, wild oat keeps the seed from which it is growing for a long time. Mature wild oat plants are easily distinguished by their open panicled, nodding inflorescence. Wild oat has a tall, pointed ligule with toothed margins and no auricles. The sturdy, mature plant is 1 to 4 feet (30 - 120 cm) tall. Leaf blades generally have hairy margins.
