Oregon Grape Holly
Mahonia is a genus of evergreen shrubs. Mahonia species typically have large, pinnate leaves 3.9–19.7 inches long with 5 to 15 leaflets, which are 2.0 to 7.9 inches long.
Several species are popular garden shrubs, grown for their ornamental evergreen foliage. There are yellow flowers in autumn, winter and early spring, with blue-black berries.
The berries are edible, and rich in vitamin C, though with a very sharp flavor. Although edible, the plants contain berberine, a compound found in many Berberis and Mahonia species, which can cause vomiting, lowered blood pressure, reduced heart rate, lethargy, and other ill effects when consumed in large quantities.
