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.

Glory-of-the-Snow is an alpine plant that preforms its flowers in the previous season so that it can flower as soon as the snow starts to melt in spring. Some plants flower immediately after snow melting or soil thawing. These early flowering plants always form their flowers in the previous season, called preformation.

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 ...
For an island so far north, this number of species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm (4 in) In some areas, especially in warmer valleys, the plants produce carpets of blossoms.
Eriophorum callitrix, commonly known as Arctic cotton, Arctic cottongrass, suputi, or pualunnguat in Inuktitut, is a perennial Arctic plant in the sedge family, Cyperaceae. It is one of the most widespread flowering plants in the northern hemisphere and tundra regions. Upon every stem grows a single round, white and wooly fruit.
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]
The arctic poppy is known for either their white or yellow flowers; these flowers can grow up to 6.5 cm in diameter. The arctic poppy stems range from 10 to 15 cm in length. Arctic poppies produce spherical or oval seed pods that are covered by fine hairs. [2]
