One of the most common plants found in the northern Arctic, moss campion is a variety of cushion plant, a slow-growing class of perennials that have adapted to hug the ground as they grow to form a cushion shape. Its characteristic shape helps the moss campion retain heat, while its small leaves keep the plant from being exposed to wind and freezing weather. Along with its clusters of dainty flowers, it grows in sandy, rocky soil in the lower Alpine.
