|synonyms_ref=[1] |}}Dodecatheon frigidum, commonly called the western arctic shootingstar, is a plant species found in arctic and subarctic regions in the northwestern part of North America and in Asiatic Russia. It is common across much of Alaska, and has also been reported from Yukon, Northwest Territories, British Columbia, northern Saskatchewan, and on the Chukotsk Peninsula in the Russian Far East (often erroneously regarded as part of Siberia). It is usually found in moist areas such as bogs, lakeshores, riverbanks, moist meadows, and heathcliff tundras. It can found on melting snow on or near permafrost.[2][3][4][5][6]Dodecatheon frigidum is an herbaceous perennial up to 40 cm (16 inches) tall, spreading by means of underground rhizomes. Each shoot produces 2-7 flowers, usually pink to magenta with a white center.[7][8][9] References1. ^Tropicos {{Taxonbar|from=Q15312485}}2. ^Flora of North America, v 8 p 277. 3. ^Cody, W. J. 1996.
