Oregon Grape

Mahonia aquifolium

An excellent, easy-care, evergreen shrub for mass planting as a screen or as a single colorful accent. Spiny foliage emerges with bronze-red coloring, turns green as it matures, and develops a purple-red coloring in the winter. Brilliant yellow flowers in spring are followed by deep blue berries in fall. Plant two or more for best berry production.

LoreThe genus name Mahonia honors American horticulturist Bernard McMahon (1775-1816). Mahonia aquifolium is knownby many different common names including Oregon grape, hollygrape or grapeholly. The slightly fragrant flowers are the state flower of Oregon. They are followed by clusters of edible berries that are not particularly tasty when eaten fresh, but can be used to make jellies and preserves.

Bloom TimeSpring
Design IdeasThis 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.
