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.
Plants in the Tundra. Plants that grow in the tundra include grasses, shrubs, herbs, and lichens. They grow in groups and stay low to the ground to stay protected from the icy winds. They tend to have shallow roots and flower quickly during the short summer months.
