Description
Canada wild rye is a perennial bunchgrass reaching heights of 1 to 1.5 metres (3 ft 3 in to 4 ft 11 in). It grows from a small rhizome, forms a shallow, fine root network, and is a facultative mycotroph, receiving about 25% of its nutrients on average from symbiotic mycorrhizae. Its stems are hollow and tough at maturity and bear rough, flat leaves. The leaves can reach 15 mm (0.59 in) in width and are 20 to 30 cm (8 to 12 in) in length. The inflorescence is a nodding spike up to 25 cm (10 in) long containing 5 to 20 spikelets. Each spikelet is 1 to 2 cm (1⁄2 to 3⁄4 in) long, not counting the sharp, hard, curling awn which may exceed 3 cm (1+1⁄4 in) in length. Many forms and varieties have been named, but none are accepted at Kew's Plants of the World Online.
