Betula ermanii
Also called Stone Birch, Russian Rock Birch, Erman’s Birch
Erman's birch is a deciduous tree, Betula ermanii, and the most cold-tolerant of the birches, prized for its peeling, creamy-white bark. The key to growing it is a cool, sunny site with moist but well-drained soil, as it dislikes heat and hot, dry summers.
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. 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.
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.
