Oregon Grape
Mahonia aquifolium
Family Berberidaceae
Est. zones 5-9
A tough native evergreen for shade — glossy holly-like leaves (bronze-purple in winter), fragrant yellow flowers that feed the earliest bees, and dusty-blue tart 'grapes' for jelly. The yellow roots are a traditional source of berberine. Spiny-leaved, deer-resistant, and it thrives in the dry shade under trees where little else will. The Oregon state flower.
