Berberis verruculosa comes from China and carries a quiet distinction that rewards close inspection. The stems are covered in small, rounded wart-like projections that give the plant its name, a characteristic visible year-round that adds textural interest even in winter. The leaves are glossy green on their upper surface with pale, glaucous undersides and spiny teeth at the margins. Narrow three-parted spines appear at each node. The overall form is rounded and arching, reaching 3 to 6 feet tall and 3 to 4 feet wide over time.

The flowers are the plant's standout quality: solitary, golden-yellow, and a full inch across, which is large for a barberry. They appear in late spring to early summer, later than most of the genus, and give way to blue-black berries in autumn that birds will eventually disperse. Partial shade to shade is preferred, and it tolerates any well-drained soil with good drought resistance once established. Zones 5 to 10 give it a broad useful range. Planted on a slope or bank it assists with erosion; as a specimen or clipped hedge it carries its Award of Garden Merit with the quiet authority of a plant that has been proving itself in gardens since 1929.
