About
Berberis potaninii is a compact evergreen shrub characterized by its robust spines, which can reach lengths of 6 cm. The foliage consists of glossy, leathery leaves that can grow up to 4 cm long, displaying a silvery white or pale silvery green hue on their undersides. In the fall, clusters of 4 to 12 yellow flowers give way to red berries.
