Low woody shrub, about 2 ft tall with thin thorns on branches.
Leaves in clusters, oval to spoon-shaped, without teeth. Flowers
bell-shaped, hanging, yellow.
An alien shrub from Asia, formerly grown as an ornamental, and now considered invasive in many places. In Wildwood, it can be found scattered in the woodlands, especially
near the top of the eastern slope, below the water towers.
One of the reasons this plant is considered noxious and undesirable is that it replaces and hybridizes with the native American barberry (B. canadensis). The native
species also occurs in Wildwood. It can be easily distinguished by
the teeth on its leaves.
