Berberis x gladwynensis 'William Penn'
|Excellent for barrier plantings, this huge group of popular thorny shrubs is attractive year-round. The especially hardy deciduous varieties have brilliant fall color. The evergreen species produce purple or blue-black berries that attract birds. Berberis thunbergii has bright red berries that last on branches into winter. Both types have plentiful yellow spring flowers and yellow inner bark and wood. Easy to grow and transplant, they tolerate many soils and climates. However, they do not like waterlogged soil. Rust on Bayberries is passed to wheat crops, so choose rust-resistant varieties such as Berberis thunbergii. Remove dead stems, and prune to shape after flowering. Cut back so inner branches do not die.
With shiny, dark green leaves that turn bronze in winter, this dense, mounding plant makes an attractive low hedge that grows faster than the Wintergreen Barberry. Partly deciduous in colder climates.
