Betula nana aka Arctic Dwarf Birch

Betula nana, also known as the dwarf birch, is a deciduous, low and spreading shrub that belongs to the Betulaceae family. It is native to the tundra landscapes of the Arctic region and is cold-hardy, growing well in areas with very cold winters. The plant has half-inch thick and leathery leaves upon hairy twigs, and its male catkins can be up to a full inch long, while female catkins are smaller. Both sexes can grow on the same plant, and the seeds ripen in July, producing narrow-winged seeded fruits that allow pollination by the wind. Arctic Dwarf Birch, a super rare houseplant, requires regular watering to thrive and does best in long-lasting, direct light that is less than a foot away from a window. It prefers soil that is well-draining, and does not require added fertilizers if repotted each time it doubles in size. Although it is related to more than 150 species of trees and shrubs, Betula nana is often not successful in milder zones and thrives best in its native Arctic tundra habitat.
