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.
There are two types of tundra-arctic tundra and alpine tundra. The arctic tundra is located within the Arctic Circle while the alpine tundra is the area high in the mountains above trees. The plants that grow in the tundra biome often grow in clusters to help protect themselves from the severe winter winds.here are very few trees that grow in the tundra biome. Under the snow and ice, there is a thick layer of soil that remains frozen which does not allow deep rooted plants such as trees to grow. The tundra biome has about 400 varieties of flowers but only 48 different animals.
