Poa arctica is a perennial grass that spreads by rhizomes and often shows purplish coloration. Stems are 7–60 cm tall. Leaves are narrow, smooth, and hairless, with ligules 2–7 mm long. The flowering panicles are 3.5–15 cm long, open and sparse, bearing 10–40 spikelets. Spikelets are 4.5–8 mm long, laterally compressed, and contain 2–6 florets. Glumes are lanceolate, sometimes keeled, and usually smooth, with moderately pronounced veins.[5]
