Description

William Penn Barberry is a broadleaf evergreen cultivar derived from crossing  B. verruculosa and B. gagnepainii.  Plant in the full sun to partial shade in well-drained soil.  Enjoy its glossy leaves with red-bronze winter color in a shrub border or use a hedge.  The thorny stems make it a good choice for a privacy screen or security plant.  It is seldom damaged by deer, drought-tolerant, and tolerates a range of soil types. Texture is medium to fine.
