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.

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.
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. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline

Alpine plants occur in a tundra: a type of natural region or biome that does not contain trees. Alpine tundra occurs in mountains worldwide. It transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as Krummholz.
The hybrid Dryas × suendermannii, with cream coloured flowers, has gained the Royal Horticultural Society's Award of Garden Merit. [ 5 ] [ 6 ] Dryas tolerates a wide variety of unshaded habitats, including alpine situations with sand or gravel substrate, similar substrates in flat tundra lowlands, and also fen habitats upon organic substrate ...
