Orchardgrass is a cool season perennial grass adapted to temperate climate areas. The branched orchardgrass inflorescence is a compact or partly spreading panicle. Seed heads are composed of spikelets that bear two to eight florets. Spikelets are attached to panicle branches by pedicels. Flowers are borne in one-sided clusters on stiff branches. Leaves vary in color from green to bluish-green. The lower surface is not shiny and has a distinct keel (center ridge). Leaf margins and leaf sheaths usually are somewhat rough to the touch when mature. Orchardgrass has good tolerance to heat and drought. It is a highly productive grass suitable for hay or pasture on well-drained soils under irrigated or nonirrigated conditions. Best used in situations where high quality management can be exercised. Orchardgrass does not have any serious insect pest problems.
