dwarf birch
Quick Summary
Dwarf birch refers to several low-growing shrubs within the Betula genus, specifically species like B. pumila, B. glandulosa, and B. nana. These are part of the larger birch family, which includes about 40 species of trees and shrubs distributed across cool Northern Hemisphere regions.12
Birches are characterized by their smooth, often white bark marked with horizontal pores, and their typically toothed, egg-shaped leaves that turn yellow in autumn. They produce male and female catkins, with the female catkins developing into cone-like clusters that release tiny, winged seeds. While some dwarf birches are used as ornamentals, they also serve as food sources for wildlife.2

FagalesBetulaceaenana (dwarf birches) are circumboreal (i.e., extending to the northern limit of the tree line); the two species very nearly coincide in their ranges, with the dwarf birches extending farther into the Arctic. They now occupy most areas that were glaciated until about 11,700 years ago.
