Zanthoxylum schinifolium, commonly known as mastic-leaf prickly ash, is a deciduous shrub native to various habitats including forest edges, thickets, and rocky hillsides in central and eastern China, Japan, Korea, Manchuria, the Ryukyu Islands, and Taiwan. It typically grows to a height of 2-4 meters with a similar spread, and is characterized by its pinnately compound leaves and spiny branches. The small, inconspicuous flowers bloom in spring and are followed by clusters of aromatic peppercorns, which turn from green to red as they mature. These peppercorns are used as a spice in Chinese cuisine, providing a unique flavor profile.

The mastic-leaf prickly ash is valued for its culinary uses and is also planted for its ornamental appeal due to its interesting foliage and textured bark. It is suitable for urban planting, border planting, and as a specimen in gardens. This shrub prefers full sun to part shade, well-drained soils, and is tolerant of a range of soil types, including clay. While it is generally easy to maintain, it can be susceptible to leaf spot disease caused by the fungal pathogen Pestalotiopsis kenyana. Gardeners should monitor for signs of infection and apply appropriate fungicides if necessary.CC BY-SA 4.0
