About
Zanthoxylum piperitum, commonly known as Japanese pepper or Sansho, is a deciduous aromatic shrub in the family Rutaceae, native to Japan, China, and the Korean Peninsula. It is an indispensable culinary herb in Japanese cuisine — the young leaves ('kinome'), flowers, and berry husks are all used as seasoning, most famously sprinkled over grilled eel. Both male and female plants exist (dioecious), and the female produces red berries in autumn that split to reveal black seeds. In bonsai, it is valued as an unusual aromatic fruiting specimen with delicate pinnate leaves and decorative red berries. Care requires attention to sharp thorns on branches during handling.
