Japanese Birch
AdvancedBetula platyphylla
A deciduous bonsai prized for its white bark. As a tree of cool highlands it suffers in lowland summer heat and dryness, so partial shade and keeping the roots cool are the keys. It shifts through fresh green, gold and bare white trunks.
About
Betula platyphylla var. japonica, the Japanese white birch (Shira-kaba in Japanese), is a deciduous tree native to Hokkaido and the northern highlands of Honshu, as well as eastern Siberia. Its luminous white bark, which peels in thin papery sheets, is the defining characteristic — an iconic symbol of the cool highland landscapes of Hokkaido and the Japanese Alps. In spring, the fresh pale green leaves emerge; in autumn, the foliage turns a clear golden yellow. In bonsai, the white bark and natural, graceful branching create a cool, airy composition evocative of highland scenery. Because it prefers a cool climate, summer heat management is the key challenge for cultivation in warmer regions.
