Birches, Betula spp., are boreal and temperate trees and shrubs, with around 50 species worldwide. Betula pendula is native and common in most of Europe, northwest Africa and western Siberia, but absent in the southernmost parts of Europe. It is the most common tree found in Scandinavia and the Alps, and a potent pollen producer in those areas. White birch is a single-stemmed, deciduous tree up to about 25 meters tall. The bark is smooth and silvery white, but can become black and fissured into rectangular bosses.
Betula pendula blooms in April – May and is collected in parks and gardens i Sweden.
