Mahonia aquifolium. Tall Oregon Grape is a native evergreen berry bush with beautiful yellow flowers in early spring which hummingbirds, bees and other pollinators love. It grows 6-8' and it's waxy leaves often gain a red hue in winter. Berries are tart and abundant and used by native peoples throughout the NW for food (usually cooked or dried) and medicine. The berries also make good jelly and wine. The plant is drought-resistant, and a great addition to a yard as a backdrop, block planting, or showpiece when pruned. Can spread by runners if given fertile soils, although it is not considered weedy by any means. Zone 5-9.
