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 PlantsClethra (Clethra); Azalea (Azalea); Sweetspire (Itea); Fothergilla (Fothergilla); Iris (Iris)

- History & LoreHistory:This evergreen shrub is native to North America, specifically to conifer forests and rocky woodlands of the Pacific Northwest, from British Columbia to northern California. This species was previously classified under the genus Berberis, and is synonymous with Berberis aquifolium.Lore:The 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.
