Rhamnus californica

Rhamnus californica

Rhamnus californica, or coffeeberry, is an evergreen shrub that can grow from three to fifteen feet, depending on the variety and the climate in which it is planted.  The common name comes from the berries that turn black once they have ripened.  It is not particular about soil and can take sun or partial shade.  Established plants need no irrigation, but will look better with at least some water.
