Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. Alpine plants grow together as a plant community in alpine tundra. Alpine plants are not a single taxon. Rather, many different plant species live in the alpine environment. These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. Alpine plants must adapt to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season. Some alpine plants serve as medicinal plants.
Species of the genus Carex are also found on the tundra. Grasses. The tundra supports some tussock-forming grasses that grow in clumps to hold tight to the ground and grow by rhizomes, or underground stems. Arctagrostis latifolia (polar grass) and Poa arctica (Arctic bluegrass) show their tundra adaptation in their names. Shrubs
