Poa arctica, commonly known as Arctic bluegrass or Arctic meadow grass, is a perennial herbaceous plant that thrives in the tundra and alpine meadows of the subarctic circumpolar region, extending into the high-altitude areas of the Rocky Mountains. It is often a dominant species in its native habitat, which includes moist meadows, riverbanks, and open, gravelly areas where it forms dense tufts or mats. This grass is well-adapted to cold environments and can be found in high-altitude regions, often responding positively to disturbance such as grazing or soil disruption.

Arctic bluegrass has a fine-textured appearance with narrow, blue-green leaves and produces inconspicuous greenish flowers during the short summer season. It is valued for its hardiness and ability to withstand extreme cold and is used in restoration projects and erosion control due to its dense root system. In cultivation, it requires minimal maintenance, thriving in full sun to partial shade and preferring moist, well-drained soils. While not commonly used in ornamental gardening, it can be a practical choice for challenging sites with cold climates.CC BY-SA 4.0
