Orchardgrass is a cool-season perennial that grows 1.4-4 ft. (0.5-1.3 m) tall. Leaves are 4-16 in. (10-40 cm) long and 0.1-0.5 in. (0.2-1.1 cm) wide with a bluish hue. The flowers occur in a panicle with spikelets in a compact cluster on one side of the rachilla. Orchardgrass is native to Europe and was first introduced to the United States in the late 1700s. It prefers areas that are well-drained with moderately fertile to rich soils. |
