Betula ermanii explained

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 20m (70feet) 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.
