- Latin: Lupinus arcticus
The Arctic lupine (or subalpine lupine) is native to northwestern North America. It can be found throughout the interior and southeast areas of Alaska, typically on tundra and in alpine areas where soils are wet. This is a perennial herbaceous species with blue, purple, or white flowers, which are sometimes tinged with pink. As a member of the pea family (Fabaceae), its fruit is a legume, which can be toxic to some animal species. For help in identification, count its leaflets. Arctic lupine should have 3-9 leaflets, as opposed to big-leaved lupine (L. polyphyllus), which has 9-17 leaflets.
