Family Berberidaceae

Mahonia aquifolium, known as Oregon grape or holly-leaved barberry, is an evergreen shrub native to western North America, highly valued for its glossy foliage and fragrant spring blooms. It forms a dense, rounded bush with leathery, deeply toothed leaves reminiscent of holly. In spring, long clusters of bright yellow flowers appear at the tips of the branches, emitting a light fragrance while attracting pollinators. These flowers are followed by small, blue-black berries covered in a waxy bloom, resembling tiny grapes and favored by birds. In autumn and winter, the foliage can take on bronze to reddish-purple hues, adding additional seasonal interest. Very hardy and tolerant, this shrub grows well in ordinary soil and adapts to semi-shaded locations.
