About Coffee Berry (Frangula californica) The California Buckthorn is also called coffeeberry because its berries contain seeds which look like coffee beans. It is a fairly common plant native to California and southwestern Oregon. It is a dense evergreen shrub growing to 6-15 feet tall, with dark red branches. The leaves are an attractive dark green with reddish tint, 1-3 inches long, with a curl under at the edges. The flowers are inconspicuous, small and greenish-white with five petals; they are produced in clusters of 5-60 together. The plant is prized more for its fruit, a berry 10-15 millimeters in diameter, which turn red, then purple and finally black over the summer. It is valued by birds. This plant is beautiful and easy to grow. It tolerates a wide variety of soil types, and likes either full sun or part shade. It is moderately garden tolerant, and is OK with light summer water up to 2x per month. Coffeeberry has a dense form and is easy to prune. It makes a great and fire resistant hedge. There are six subspecies, some of which are restricted to certain parts of its range or certain growing requirements. There are also a number of horticultural varieties including 'Eve Case' and 'Mound San Bruno'. Check for the one that best fits your locations and conditions.
