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.

The Arctic willow grows in tundra [7] and rocky moorland, and is the northernmost woody plant in the world, occurring far above the tree line to the northern limit of land on the north coast of Greenland. Its distribution is circumpolar.
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
In addition to species such as lichens, cotton grass, and Arctic willows, shrubs, sedges, lichens, mosses, and vascular plants dominate the tundra plant community (Folch and Camarasa 2000). Despite the tundra eco-region's reputation of being a cold and desolate ‘polar desert’, it is actually a varying landscape supporting a diverse amount ...
Papaver radicatum (arctic poppy), a flowering plant of the Arctic tundra follows the sun around the sky during the 24-hour daylight of summer north of the Arctic Circle. Changing climate conditions are amplified in polar regions and northern high-latitude areas are projected to warm at twice the rate of the global average. [1]
Saxifraga oppositifolia - MHNT. Saxifraga oppositifolia, the purple saxifrage or purple mountain saxifrage, [1] is a species of plant that is very common in the high Arctic and also some high mountainous areas further south, including northern Britain, the Alps and the Rocky Mountains.
This plant is common in many Arctic regions, growing in several types of cold, wet habitat. It can be found in tundra, meadows, river valleys, and scree slopes. It anchors well in rocky and gravelly substrates, and it thrives in soils with low organic content. It is a pioneer species in rough terrain. [4]
Arctostaphylos rubra is a species of flowering plant in the heath family and the genus Arctostaphylos, the manzanitas and bearberries. Common names include red fruit bearberry, alpine bearberry, arctic bearberry, red manzanita, and ravenberry. It is native to Eurasia and northern North America from Alaska through most of Canada to Greenland. [2]
