DESCRIPTION:
Orchardgrass, also called cock's foot, is a perennial bunchgrass which resprouts from underground stems or germinates from seeds in winter. Seedlings are light green with broad leaf blades. As with leaves on mature plants, second and third leaves have fringed or torn ligules at the base of the leaf but lack auricles. Mature plants range from 1 to 3.6 feet (30 - 110 cm) tall and have leaves arising from the plant base and the stem. Leaf blades are broadly linear, roughened, and roughly 1/10 to 1/4 inch (3 - 6 mm) wide. The branched flowering head is 4 to 6 inches (10 - 15 cm) long with flowers clustered in dense, one-sided groups of two to four at ends of branches. Flower branches are erect or spreading and the lowermost stands separate like the spur on a cock's foot, hence the common name.
