Frangula californica 'Mound San Bruno' (San Bruno Coffeeberry) - A very nice selection of the California native Coffeeberry. This evergreen shrub is more compact than the species. It can typically be found growing to 4-6 feet tall and twice as wide as it is tall with leaves that about half the size of the species and other cultivars. Originally thought to make a small mound to only 3 feet tall however the largest plant that we know of has grown to 6 feet tall and is nearly 14 feet wide and we have been told of plants reaching 8 feet tall. The greenish-white flowers are inconspicuous, but they do produce many dark red, almost black, berries. Grows in full sun or light shade.
Grows well in full sun or light shade. A hardy shrub that can grow in most soils, but best in a sandy well-drained soil. Drought tolerant once established and cold hardy to 5° F and possibly a bit colder. Can be pruned to shape of even trained up as a small tree. A great plant for the natural California garden and useful on a slope for erosion control. Its flowers and fruit are attractive to wildlife, yet it is relatively resistant to predation by deer.
