Festuca altaica
A circumboreal, cool-season perennial bunchgrass with dense tufts and an extensive root system, well adapted to fire and an important forage species for livestock and wildlife, found across northern North America.
Common Names
Altai Fescue, Northern Rough Fescue, Rough Fescue
Summary
Altai fescue is a densely tufted perennial bunchgrass with short rhizomes, producing culms 60–100 cm tall and stiff, rough leaves 2–4 mm wide. The open panicle inflorescence bears spikelets 8–14 mm long that are purple to brown, giving a distinctive appearance during flowering. Native to circumboreal regions of Asia and North America, it occurs in Arctic tundra and boreal/subalpine habitats from Alaska to Michigan and across Siberia and parts of Asia.
Preferring well-drained mesic to dry meadows, Altai fescue tolerates cold climates and is shade-intolerant. It requires disturbances such as grazing or fire to maintain openings, with prescribed spring burns recommended and late-spring burns to be avoided. In landscape and management contexts, it serves as an erosion-control and ornamental species and as forage for livestock.
