Patches that grow in the shade of dwarf shrubs, mostly various Salix species, particularly Salix arctica, recall the species' sylvan beginnings.

Species from the Alaskan coastline and islands have also adapted well in the Faroe Islands, especially Pinus contorta, Picea sitchensis, Salix alaxensis, Populus trichocarpa and Alnus sinuata. The biggest Alaskan pine tree (Pinus contorta) in Europe (in width, not in height), is to be found in the Selatrað plantation in the Faroe Islands.
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.

In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera, Salix, Populus, and Chosenia (now a synonym of Salix). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales.
These include the Arctic willow (Salix arctica). The Arctic willow may be up to around 7.6 m (25 ft) horizontally, but only 150 mm (6 in) tall. The climate of Iqaluit is also colder than Gulf Stream locations on the same latitude. For example, the Norwegian city of Trondheim has an annual mean temperature that is 15.2 °C (27.4 °F) milder.
