Mahonia aquifolium (Hollyleaved barberry)
Makin, Julie
Holly-leaf Oregon-grape is a 3-6 ft., mound-shaped, broadleaf evergreen shrub with pinnately compound, glossy, leathery leaves. The 5-9 dark-green leaflets are armed with spiny teeth and turn reddish in fall. Terminal clusters of bright-yellow, bell-shaped flowers are followed by clusters of tiny blue, grape-like fruits. The bronzy copper color or the new growth in spring is an added bonus.

This stout shrub is the state flower of Oregon. The berries of this and other Oregon-grape species are eaten by wildlife and make good jelly. Native Americans made a yellow dye from the bark and wood of this shrubby species. Several are used as ornamental garden plants; in the nursery trade some of them are known by the common name Mahonia.
