About This Plant

Mahonia nervosa (Dwarf Oregon Grape), 'Dwarf Oregon Grape', is valued for its garden character and seasonal interest in PNW landscapes.

Mahonia nervosa is an ornamental shrub valued for its seasonal interest and the role it plays in the garden landscape.

Full sun to part shade suits this species. Plant in moist, well-drained soil. Hardy USDA Zone 5 to 9. Provide consistent moisture during establishment. Watch for general pest pressures common to the region.

Care Notes

Plant in acidic, humus-rich, well-drained soil. Keep consistently moist during the first 1-2 years; drought-tolerant once established. Avoid hot afternoon sun. Spreads slowly by rhizome to form a low groundcover. Protect young plants with temporary wire cages; deer and elk browse low Oregon grape, especially in winter.
