Helping You Become a More Successful Gardener
BERBERIS x mentorensis
Mentor Hybrid Barberry
This entry has yet to be reviewed and approved by L2G editors.
The Mentor barberry is an exceptionally resilient shrub for hedging and deterring trespassers. It originated in Mentor, Ohio, as a hybridization between wintergreen barberry (Berberis julianae) and Japanese barberry (B. thunbergii). Slender yellowish yet stiff branch shoots grow from this generally rounded but upright shrub that's semi-evergreen. The colder the winter, the progressively more deciduous it becomes.
The new foliage in springtime is chartreuse-green, and then matures to green by summer. The oval leaf blades have toothed tips and have paler green undersides. Easily overlooked yellow flowers occur along the branches in spring, resulting in a flurry of bees for pollination. The ensuing fruits are also overlooked, being a drab red-brown. In autumn, Mentor barberry dazzles with a changeable yellow to orange to red display.
For faster growth and best performance, plant Mentor barberry in full to partial sun and any moist but well-drained soil. It is remarkably tolerate to a wide range of soil conditions, including the seemingly inhospitable environs of urban settings. Use it as a dense, impenetrable hedge (as it responds to sheering just fine) or as a specimen. Birds often use the shrub for cover from predators. One maintenance drawback is that the dense twigs tend to capture and retain garbage and leaf litter over time.
