Zanthoxylum consists of spiny, deciduous or evergreen trees and shrubs that typically have a rounded or upright form. Their bark and foliage emit a noticeable aroma. In the spring or summer, clusters of small green or yellow-green flowers emerge, which are succeeded by small fruits that open to expose seeds connected by short threads.

Zanthoxylum simulans is a medium to large deciduous shrub or small tree characterized by its bushy, spiny growth. The leaves resemble those of ash trees, reaching lengths of up to 8 cm and featuring as many as 11 broad leaflets. In early summer, it produces flat-topped clusters of small, yellow-green flowers, which are followed by open groups of small red fruits that split to reveal black seeds. All parts of the plant, including the leaves, bark, and fruit, emit a fragrant aroma. This species can be cultivated for culinary use, as its dried seed pods serve as a condiment with a flavor profile that surpasses that of black pepper.
