Mahonia aquifolium
Oregon Grape
This PNW native shrub is the state flower of Oregon. Known for its evergreen, holly-like leaves that turn deep burgundy in winter and racemes of Sulphur-yellow flowers in spring. New leaves are reddish when they emerge and the bright ephemeral blooms are followed shortly by blue-black berries that somewhat resemble clusters of grapes. The berries are edible but quite sour. (Shrub)
