Warty Barberry

Berberis verruculosa (BER-ber-is ver-ruk-yoo-LO-sah)

Family: Berberidaceae Non-native Shrub (3-15 ft)

Warty barberry is an evergreen shrub in the barberry family (Berberidaceae) native to China. It gets its common name from the rounded raised spots on the stems. This shrub grows 3 to 6 feet tall and 3 to 4 feet wide in a rounded arching form. It prefers partial shade to shade and tolerates any well-drained garden soil. It is drought-tolerant once established. Propagate by seed or stem cuttings. Spreads to form thickets. Birds will spread the seeds. The solitary golden-yellow flowers are 1 inch across and appear in late spring to summer. They are followed by blue-black berries in the fall. The leaves are glossy green with glaucous undersides and spiny teeth. The stems have narrow three-parted spines. The plant has been awarded the Royal Horticultural Society's Award of Garden Merit in 1929. Warty Barberry can be used as a specimen, hedge, or barrier plant. It can also be used on slopes and banks to help with erosion. Quick ID Hints : Stems covered in tiny wart-like excrescences Leaves on dwarf shoots, 3-parted spines at nodes Leaves green or reddish above, tomentose underneath Insects, Diseases, and Other Plant Problems: Watch for berberis sawfly and powdery mildew. Deer resistant. More information on Berberis .
