Species of flowering plant in the carnation family Caryophyllaceae

Silene acaulis, known as moss campion or cushion pink, is a small mountain dwelling wildflower that is common all over the high arctic and tundra and in high mountains of Eurasia and North America (Alps, Carpathians, southern Siberia, Pyrenees, British Isles, Iceland, Faroe Islands, Rocky Mountains). It is an evergreen perennial flowering plant in the carnation family Caryophyllaceae. It is also called the compass plant, since the flowers appear first on the south side of the cushion. (Various other plants also have this name.)

Moss campion is a low, ground hugging plant. It may seem densely matted and moss like. The dense cushions are up to a foot or more in diameter. The plants are usually about tall but may be as high as 6 feet (2 m). The bright green leaves are narrow, arising 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 that may be up to long, but are usually much shorter. It usually has pink flowers, though very rarely they may be white. They are between wide, with hermaphrodite flowers being larger than the female ones. Female flowers produce better quality seeds than hermaphrodites and male flowers produce better quality pollen than hermaphrodites. The cushions can change the gender of their flowers between years. Gender frequencies change with altitude, the frequency of female flowers increasing with higher elevation. The flowers are held by a calyx which is rather firm and thick. The sepals are joined together into a tube that conceals the bases of the petals, which are entire. The 10 stamens and 3 styles extend well beyond the throat of the flower. The stems and leaves are very sticky and viscid, which may discourage ants and beetles from climbing on the plant.

Moss campion is common all over the high arctic and the higher mountains of Eurasia and North America (south to the Alps, Carpathians, southern Siberia, Pyrenees, British Isles, Iceland, Faroe Islands, Rocky Mountains). In the United States it inhabits Colorado, the Bighorn Mountains of Wyoming, the Wallowa Mountains of Oregon, the Olympics, the northern Cascades of Washington, and Alaska. and in New Hampshire Silene acaulis var. exscapa is threatened. However, a study on four populations across a latitudinal gradient in North America showed that southern populations of moss campion had lower survival and recruitment, but higher individual growth, rates than more northern populations. Furthermore, vital rates such as growth, survival, and fruits per area were shown to increase in moderately warmer years yet declined in the very warmest years, suggesting that a change in climate into warmer conditions or more frequent unusually warm summers may eventually lead to negative impacts. Another study showed that, while the short term responses were positive, they turned negative on medium term, suggestion that moss campion may be at risk in future global warming. Projections produced under different climate scenarios suggest that S. acaulis will likely face climate driven fast decline in suitable areas on the British Isles and across North America, and that upward and northward shifts to occupy new climatically suitable areas are improbable in the future.

The seeds should be sown early in the spring time. Put the seedlings into separate pots, and it is recommended to let them winter in the greenhouse for their first winter season. To clean them rub the capsules through a screen. It is advised to plant them in the late spring or early summer because division takes place in the spring. They should be grown in well drained soil with full sun. The climate can be cool.

There is no listing that moss campion is toxic, though it does have saponins which, though toxic, are hard to absorb in the body. They can be broken down by thorough cooking. Its advised to not consume large amounts of this plant.

The plant used to be used for children with colic. The raw root skin plants were consumed as a vegetable in Iceland and in Arctic regions.
