Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

Silene acaulis, known as moss campion [2] or cushion pink, is a small wildflower that is common all over the high arctic and tundra and in high mountains of Eurasia and North America (Alps, Carpathians, southern Siberia, Pyrenees, British Isles, Iceland, Faroe Islands, Greenland, Rocky Mountains).
The compact growth form of cushion plants reduces air flow over the surface of the epidermis, reducing the rate of water loss. Additionally, many cushion plants have small and fleshy leaves which reduce the surface area of the plant, which reduces transpiration and conserves water. In alpine environments well above the tree line, cold is a ...
These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [2] Alpine plants are adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, wind, drought, poor nutritional soil, and a short growing season. Some alpine plants serve as medicinal plants.
Leucobryum glaucum, commonly known as leucobryum moss or pin cushion moss, is a species of haplolepideous mosses with a wide distribution in eastern North America and Europe. [ 1 ] [ 2 ] [ 3 ] It inhabits temperate forests in the Northern Hemisphere, and its structure allows it to absorb metal ions.
The team also subjected the plant to Mars like conditions—a 95-percent-CO2 atmosphere, temperatures ranging from −60 degrees Celsius to 20 degrees Celsius, high levels of UV radiation, and low ...
