Zanthoxylum ailanthoides is a spiny, deciduous Asian tree in the citrus family whose aromatic, peppery fruit is used as a local spice, and its young leaves are eaten in Taiwan. It is mainly a forest tree grown for its fruit and as a source of pepper-like flavor rather than a common ornamental.

About
Zanthoxylum ailanthoides, also called ailanthus-like prickly ash, (Chinese: 椿叶花椒; pinyin: chun ye hua jiao, lit. "Ailanthus-leaved pepper", Chinese: 越椒; pinyin: yue-jiao; Wade–Giles: yüeh-chiao, lit. "Yue pepper", 食茱萸 shi zhu yu, lit. "edible shān zhū yú"; Japanese: カラスザンショウ, からすのさんしょう karasu-zanshō, karasu-no-sanshō, lit. "crow prickly ash") is an Asiatic plant of the prickly-ash genus Zanthoxylum, natively occurring in forest-covered parts of southeastern China, Taiwan, Southeast Asia, and Japan from Honshu southward. The piquant fruit serves as a local substitute for the ordinary red-pepper in China before the Columbian exchange. In Taiwan, the young leaves are used in cuisines.
Though some refer to the species as "Japanese prickly-ash", that name is confusing since it is sometimes applied to the sanshō which is Z. piperitum. Z.
