Plant of the week Mahonia repens Creeping Oregon Grape Holly Mahonia repens is an evergreen groundcover that has a showy display of color all year long. Its stiff branches hold spiny-toothed, leathery leaves that are glossy green in the summer, and turn a purplish-red in the fall and winter. In May its bright yellow flowers bloom in clusters, and are followed by blue, grape-like berries that ripen in August. It can grow up to 18” tall and spread up to 4’ wide. It spreads by underground stems to form an attractive ground cover. Creeping Oregon Grape Holly is native to the Rocky Mountains, from Canada to Texas. It grows naturally underneath pine and fir canopies, and on rocky, gravelly slopes. Native American tribes used the berries and stem wood for dyes, and made tea from its roots. Its berries are edible to humans once they have passed through at least one frost; otherwise they are mildly toxic. Mahonia repens prefers moist, acidic soils, but will grow well in rocky, dry sites as well. Plant it in full to partial sun. It survives on very little water, but will spread faster with regular watering. It is hardy to zone 4. Durango Nursery and Supply sells Mahonia repens in #1 pots.
