California barberry, shiny leaf mahonia
Similar to Oregon grape (Mahonia aquifolium) but leaves are more crinkly and spiny. New growth often shows lots of red and orange. Grows upright to 6 ft. or more, particularly in ideal coastal sites. Handles drought better than the Oregon grape. Tolerates sun to shade. Best with a little shade in hot areas. Fruits eaten by robins, finches and towhees. The flowers have nectar for hummingbirds and bees. Deer resistant.
