Berberis thunbergii D C. is a deciduous branched shrub that can reach 1 m in height. Grooved or angled twigs are glabrous and pinkish-green when young, turning reddish-pink at maturity. The solitary or trifurcate stem has spines at each node with the internode being 1-1.5 cm. The papery leaves are obovate, spatulate, or spoon shaped, 1-2 cm long and 5-2 mm wide, apiculate or obtuse apically and cuneate at the base, with entire margin. Usually in small clusters of two to five blossoms, flowers are grayish yellow with two glands near the base of the obovate petal, and appear from April to June. Fruits are bright red elliptic berries, 8 mm long and 4 mm in diameter, appearing from July to October
