Cultivation Details

Zanthoxylum nitidum is a plant mainly of the tropics and subtropics and is unlikely to tolerate much, if any, frost. Its range extends to hardiness zone nine in southern China (from Yunnan to Zhejiang) and so it might also succeed outdoors in the warmest parts of the temperate zone.
Prefers a good deep well-drained moisture retentive soil in full sun or semi-shade[, , ].
Flowers are formed on the old wood[].
A dioecious species, both male and female forms must be grown if seed is required. Occasional plants have both male and female flowers (monoecious)[].

Edible Uses

The fruit is used as a spice[, ].

Propagation

Seed - best sown as soon as it is ripe. Stored seed may requires up to 3 months cold stratification, though scarification may also help[]. Germination should take place within 6 months, though it might take another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them until large enough to plant out.
Cuttings of half-ripe wood.
Root cuttings, 3cm long, planted horizontally in pots. Good percentage[].
Suckers, removed when the plant is dormant, and planted direct into their permanent positions[].
