Catalog Description
Excellent shrub for massed planting as hedge or screen or planted singly for color accent. New holly-like growth has bronze-red coloring. Purplish-red leaves in winter. Yellow flowers followed by blue berries. Full to partial sun. Irregular, erect stems; grows to 3 to 6 feet tall and wide. Seed grown.
Design Ideas

This valuable Western native is at home under the high canopies of the pine and fir forests of its home range on the Pacific Coast. A very appropriate plant for natural wild gardens in the Western states, where it is reliably deer resistant. Tall and thin, it is perfect for very narrow spaces at tight gateways and side yards. Often planted hedge-style against fences and walls, but may be used as a freestanding hedge in narrow slots between driveways. Blends into plantings of acid-loving shrubs and trees. Fills odd spots and covers water pipe valves and utility boxes. A common plant in both drought-resistant and Western native landscapes. Works well in Japanese gardens.
Companion Plants

Oregon Grape grows in the wild with Lemon Leaf (Gaultheria shallon), Vancouver Jade Kinnikinick (Arctostaphyllus uva-ursi `Vancouver Jade`) and a relative of American Rhododendron (Rhododendron catawbiense `America`).
It is at home beneath native trees such as Coast Live Oak (Quercus agrifolia), Santa Cruz Coast Redwood (Sequoia sempervirens `Santa Cruz`) and Rocky Mountain Douglas Fir (Pseudotsuga menziesii `Glauca`).
