This plant is a matted, cushion-forming perennial herb with erect or prostrate stems just a few centimeters long. The leaves are up to 5 centimeters long and are each made up of several leaflets.[1] The herbage is coated in silvery gray hairs.[2] The inflorescence is a raceme of one or two purple or blue-violet flowers. Flowering occurs in June. The fruit is a papery, inflated, hairy, black legume pod up to 2.5 centimeters long.[1][2]
This is a plant of arctic habitat types such as tundra. The northernmost record is from Southampton Island in the Canadian Arctic Archipelago.[2] To the south in the Rocky Mountains it occurs in alpine climates in meadows and barren mountain habitat. In Colorado it occurs at elevations up to 4030 meters (12,500 feet).[1]
