Arabidopsis arenicola, the Arctic rock-cress, is a plant species native to the northeastern part of North America. It has been reported from Greenland, Labrador, Nunavut, Northwest Territories, Québec, Ontario, Manitoba, and Saskatchewan. It grows on sandy or gravely beaches or stream banks at elevations below 1,500 metres (4,900 ft).[3][4][5][6]
Arabidopsis arenicola is a perennial herb up to 30 centimetres (12 in) tall, usually hairless or almost hairless. Basal leaves are up to 6 centimetres (2.4 in) long; stem leaves up to 2.5 millimetres (0.098 in) long. Flowers are white, up to 10 millimetres (0.39 in) across. Fruits are straight, smooth, cylindrical or slightly flattened, up to 3 centimetres (1.2 in) long.[3][7][8][9][10]
