They produces leather, linear to very broadly ovate or obovate, smooth edged or spine toothed leaves. Weak to quite fierce spines are borne in groups of threes and persist on old, leafless stems. Barberries are grown for their foliage (ornamental or giving good autumn color), small racemes, panicles, or axillary clusters of yellow to dark orange, cream or reddish flowers, cup shaped usually reflexed sepals, followed by colorful autumn fleshy fruits. They range from dwarf species and cultivars to large shrubs that are effective in a border, as specimen shrubs, or hedges. Site with care as branches can be hazardous.
