Walk through a forest near my home in Portland, Oregon and you will often find Oregon Grape carpeting wide swaths of land. In city and suburban gardens, the taller Oregon Grape (Berberis aquifolium) is often planted as a hardy perennial for its pretty year round glossy green foliage, yellow flowers and blueberries. This is a plant that is near and dear to many herbalists as it is deeply useful for a variety of health complaints.
