Elymus innovatus

Leymus innovatus is a species of grass known by the common names downy ryegrass, boreal wildrye, hairy wildrye, fuzzyspike wildrye, northern wildrye, and northwestern wildrye. It is native to northern North America from Alaska to eastern Canada and south to South Dakota.[1][2]

This perennial grass reproduces by seed or by spreading via its rhizomes. The stems grow up to about 80[1] to 105 centimeters tall.[2] The inflorescence is a spike up to 16 centimeters long by 2 wide, with spikelets in pairs or threes.[2]

This grass is often a dominant species in the understory of lodgepole pine forests. It commonly grows with other plant species such as russet buffaloberry (Shepherdia canadensis), bluejoint reedgrass (Calamagrostis canadensis), rough fescue (Festuca altaica), jack pine (Pinus banksiana), and white spruce (Picea glauca).[1]
