Barley

Upright winter annual that grows 1 1/2 – 3 feet tall. Has hollow jointed stems with narrow, tapered leaves. Leaves are broader than those of most other grasses. Flower spikes appear bearded because of their long awns. Winter barley requires vernalization to produce grain; spring types do not.
