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.

Dryas octopetala, the mountain avens, [2] eightpetal mountain-avens, white dryas or white dryad, [3] is an Arctic–alpine flowering plant in the family Rosaceae.It is a small prostrate evergreen subshrub forming large colonies.
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, [2] Alpine, [2] and Antarctic. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens ...
Rough saxifrage is predominantly a plant of the Arctic tundra. It is one of only two species in the Saxifraga section Trachyphyllum (the other being Saxifraga bryoides) to extend is range into Western Europe where it is found at altitudes of between 1,400 and 3,000 metres (4,600 and 9,800 ft) in the Alps, Pyrenees and northern Apennines.
It can also form a symbiosis with the mushroom Hebeloma cylindrosporum via an ectomycorrhiza. [9] 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 ...
The amount of vegetation in the tundra consists on how much sun, or snow cover is in the area. The vegetation in this area may grow as tall as 50 cm (20 in). In the southern part of the Arctic, there tend to be more shrubs whereas the northern parts there is less plant cover. In wet areas of the tundra, there is tussock grasses and cotton grasses.
As climate change brings more severe heat, it is testing iconic desert plants known to thrive in harsh environments, including saguaro cacti and agave. ... Arctic blast brings widespread snow ...
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
