Zanthoxylum simulans – Chinese pepper tree
The Chinese pepper tree (Zanthoxylum simulans) is an aromatic shrub or small tree native to East Asia, known for its fragrant berries with a sharp and lemony flavor.
Origin and Characteristics
Originally from China (Sichuan region), Zanthoxylum simulans belongs to the rue family (Rutaceae), like citrus fruits. It is also called Sichuan pepper, Chinese Zanthoxylum, or false pepper shrub. Despite its name, it is botanically not a pepper plant, but its spicy husks are used similarly.
It is valued for its frost hardiness, thorny bushy growth, and, of course, its production of aromatic berries.
Description and Features
The Chinese pepper tree grows as a branched, dense bush, often with thorny branches. The leaves consist of small, dark green leaflets that emit a lemony scent when crushed. The inconspicuous yellow-green flowers appear in spring, followed by small red capsules that open in late summer releasing shiny black seeds.
