Zanthoxylum simulans

The Sichuan pepper, Zanthoxylum simulans, is a much under-appreciated deciduous shrub or small tree that offers so many reasons to grow it.

Hailing from China and Taiwan, it bears attractive compound leaves like those of ash and clusters of elder-like, cream flowers in late spring and early summer. In autumn bright red fruits ripen and gradually split open to reveal glossy black seeds within. As autumn progresses, the leaves turn a vivid shade of yellow, contrasting beautifully with the red fruits. To top it all off, the leaves, bark and fruits are all aromatic, with a spicy, citrusy scent. The red seed cases are edible and can be used as a pepper substitute, as are the leaves and bark. You can also find highly attractive multi-stem specimens of this shrub.

For best results, grow Zanthoxylum simulans in full sun or dappled shade in fertile, well-drained soil. It generally doesn't require pruning as it will naturally form an attractive shape as it grows. However, pruning to restrict its size can be carried out in late winter or early spring.
