About
Zanthoxylum simulans or related species, known as Chinese pepper tree or Sichuan pepper tree (similar to Japanese sansho), is a deciduous aromatic shrub in the family Rutaceae, native to China, Japan, and the Korean Peninsula. When bark or wood is cut or damaged, a vivid yellow inner bark is revealed — a distinctive characteristic prized in bonsai for the visual contrast it provides between the yellow heartwood and autumn-colored foliage. The pinnate leaves are aromatic, and small red berries appear in autumn. The species responds well to pruning and develops characterful bark with age. Protective gloves should be worn during handling due to thorns on the branches.
