About
Carpinus japonica, commonly known as Japanese hornbeam or Kuma shide, is a deciduous hornbeam tree endemic to Japan, found in mountain forests of Honshu, Shikoku, and Kyushu. Its name 'shide' refers to the papery pendulous fruiting catkins that resemble the paper streamers used in Shinto ritual. The leaves are broadly ovate with strongly impressed parallel veins. In bonsai, it is prized for its elegant fine branching, smooth muscular bark, and attractive autumn color ranging from yellow to orange-brown. It is primarily cultivated as a literati or informal upright bonsai, and responds well to regular pruning and pinching.
