DESCRIPTION:
Hare barley, frequently called wild barley, is a winter annual. Seedlings have hairy foliage, similar to those of wild oat. Plants have papery ligules and characteristic long and narrow auricles clasping the stem. Leaf blades are 1 to 5 inches (2.5 - 12.5 cm) long. Flower heads are dense and bristly with conspicuous awns. The mature plant is 6 to 24 inches (15 - 60 cm) tall. It grows in spreading tufts and has an overall soft, velvety look. At maturity, flower spikes break apart into several pieces.
