Rhamnus californica ‘Mound San Bruno’ is a small low-growing, evergreen shrub that has stunning red twigs and bark that are contrasted with intense green foliage. This shrub cultivar is exclusive to the San Bruno Mountain area in South San Francisco. It’s ideal for use in a small garden as a feature plant or as a hedge. It requires minimal water but is less tolerant of heat and drought than other varieties of coffeeberry. The shrub flowers in the mid to late spring with berries fading from bright red to black in the fall. It grows best in sandy, fast-draining soil and prefers sun or partial shade in coastal sites, and mostly shade in inland areas.
