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.
Approximately 1,700 species of plants live on the Arctic tundra, including flowering plants, dwarf shrubs, herbs, grasses, mosses, and lichens.The tundra is characterized by permafrost, a layer of soil and partially decomposed organic matter that is frozen year-round.hen we think of the word âplantsâ we typically picture trees, bushes, grasses, and ferns â so-called âvascular plantsâ because of their full systems of leaves, stems, and roots. However, the plant kingdom also includes mosses, liverworts, and hornworts, simpler plants that lack these water-transporting structures.
