Betula ermanii in Kuril nature reserve

Betula ermanii, or Erman's birch, 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.[1] 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.[2]

The cultivar 'Grayswood Hill' has gained the Royal Horticultural Society's Award of Garden Merit.[3]
