About
A deciduous shrub to 2.5m tall, with spiny stems bearing pinnate leaves composed of 11-21 aromatic leaflets. The foliage turns golden yellow in autumn. In late summer it produces clusters of small, yellowy-green flowers; these are followed by spherical, red fruits that split to reveal glossy black seeds. The fruits are used as spice in Asian cuisine.
