Common Alpine Wildflowers of Mount Revelstoke National Park

Moss Campion (Silene acaulis) Moss Campion (Silene acaulis)

Moss campion is a classic ‘cushion plant’. Cushion plants grow low to the ground and no living part of the plant projects above the cushion surface. This growth form is common in arctic and alpine environments, because the cushion absorbs the sun’s warmth and traps still, warm air. A difference of over 15ºC between air temperature and the temperature in a cushion plant is possible. The cushion also traps wind-blown particles that nourish the plant.
