Moss Campion (Silene acaulis)
Flowers common to Artic and tundra habitats. Low, ground-hugging plant. The bright, green leaves are narrow and arise from the base of the plant. The dead leaves from the previous season persist for years, and pink flowers are borne singly on short stalks up to 1 and 1/2" long, but are usually much shorter. It usually has pink flowers and very rarely they will be white.
Keen of Hamar, Unst. Alpine fellfield, on windswept rocky ridges and summits above treeline. It grows mainly in dry, gravelly localities, but also in damper places. With the cushions it produces its own, warmer climate with high temperatures inside, when the sun shines. (June, 2013)
