Betula pubescens , commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch  but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch.
