Creeping Mahonia

You spot Creeping Mahonia as a low groundcover (1-2 feet tall) forming evergreen mats on rocky or sandy sites throughout drier portions of the Pacific Northwest. Its holly-like pinnate leaves and creeping rhizomes adapt it perfectly to erosion-prone slopes and drought-stressed settings.

Creeping Mahonia spreads via underground stems and grows vigorously in sun to part shade with low to moderate water needs (zones variable). It tolerates poor, well-drained soils and rocky terrain where few plants compete. Once established, it requires minimal maintenance and suppresses weeds effectively. Susceptibility to rust, leaf spot, powdery mildew, and lecanium scale matches other berberis species; monitoring in humid summers prevents serious damage.
