Betula ermanii, or Erman's birch, [1] is a species of birch tree belonging to the family Betulaceae. It is an extremely variable species and can be found in Northeast China, Korea, Japan, and Russian Far East ( Kuril Islands, Sakhalin, Kamchatka). It can grow to 20 metres (66 ft) tall. [2] It is noted for its peeling bark, which can sometimes be removed in sheets, but usually shreds and hangs from the trunk and under branches. Yellow-brown male catkins appear with the leaves in spring. [3]

Erman's birch is widely cultivated outside its natural range. The cultivar 'Grayswood Hill' has gained the Royal Horticultural Society's Award of Garden Merit. [4]

Leading tree nurseries including Barcham Trees [5] stock the species. It is consequently a frequently encountered street tree in London and other British towns and cities.
