Quercus suber is an evergreen tree with unique bark characteristics. The bark contains high amounts of suberin, which is a waxy substance that is waterproof. With that, the bark has been used to produce corks for wine bottles for years. The trees’ average growth is around 40-70 feet tall and wide. They can grow bigger, but it’s not very common.

Evergreen shrub that has insignificant flowers followed by black berries. Flowers are attractive to pollinators, especially bees, and berries provide a food source for birds. Cultivars commonly sold in nurseries have differing growth habits and are often smaller than the species which grows 5-18’ x 10-18’.

Examples: F. c. ‘Eve Case’ (6-8’ x 6-8’), R. c. ‘Leatherleaf’ (5-6’ x 5-6’), R. c. ‘Mound San Bruno’ (6-8’ x 6-8’) with a dense, mounding growth habit.

Note: California coffeeberry was formerly classified as Rhamnus californica and is now classified as Frangula californica.

Group of shrubs typically grown for their foliage as background plantings, hedges, or screens. Italian buckthorn (Rhamnus alaternus)—a large, evergreen shrub that grows 12-15’ tall and wide from the Mediterranean region—is the most widely available of the buckthorns. Italian buckthorn is adapted to coastal and inland environments and tolerates clipping and pruning well. R. a. ‘Variegata’ has leaves with cream edges.

Two species of Rhaphiolepis and many cultivars are widely available in California. These evergreen, flowering shrubs and small trees provide attractive foliage and clusters of pink or white flowers from spring into fall followed by dark blue fruits.

• Indian hawthorn (R. indica, 4-5’ x 5-6’) has a mounding growth habit and is available in many cultivars at local nurseries offering a range of size and flower variations.
• i. ‘Majestic Beauty’ (R. montic 10-18’ x 8-10’) deserves special mention as it is larger than other available cultivars and can be trained as a small, single- or multi-trunked tree.
• Yeddo hawthorn (R. umbellata, 4-8’ x 4-8’) has white flowers and more leathery leaves than Indian hawthorn.

Diverse group of resilient shrubs and trees, including several that are native to California, that provide form, foliage, and habitat value.

• Lemonade berry (R. integrifolia, 4-20‘ x 4-20’) is native to coastal Southern California and Baja California. This evergreen shrub provides white-to-pink clusters of flowers in late winter and early spring followed by sticky, reddish fruits. Lemonade berry is more suitable for coastal climates, whereas sugar bush will also grow in hotter areas.
• Sugar bush (R. ovata, 4-10’ x 4-10’) is native to dry slopes away from the coast in Southern California and Baja California. Similar to lemonade berry with more reddish flowers and leaves that are often folded down the center.
• African sumac (R. lancea, 15-25’ x 20-30’) is an evergreen tree from South Africa with willow-like leaves and graceful weeping habit.

Note: The infamous poison oak was previously classified within the Rhus genus, but has since been reclassified to the more appropriate sounding Toxicodendron diversilobum.

Currants (without spines) and gooseberries (with spines) are grown for their graceful growth habit, attractive foliage, wonderful displays of pendulous flowers in winter-spring that are attractive to hummingbirds, and colorful fruit that provides a food source for birds. Most of the species listed are deciduous, going dormant in the summer months.

Examples: Some of the species suitable for California gardens, preferably with partial shade, are native to the Western United States:

• aureum, golden currant (5-10’ x 3-6’), deciduous with small clusters of delicate yellow flowers and sprawling habit.
• malvaceum, chaparral currant (4-8’ x 4-6’), deciduous with early clusters of pink flowers, a slightly vase-shaped habit, and more drought-tolerant than most species.
• sanguineum var. glutinosum, pink-flowering currant (5-12’ x 5-12’), deciduous with maple-like leaves, a vase-shaped habit, and long pendulous clusters of pink, reddish, or white flowers in the spring; many available cultivars such as ‘Claremont’, ‘Tranquillon Ridge’, and ‘White Icicle’.
• speciosum, fuchsia-flowered gooseberry (4-8’ x 6-10’), deciduous with spiny, arching stems and bright red fuchsia-like flowers along the stems in the spring that are attractive to hummingbirds.
• viburnifolium, evergreen currant or Catalina perfume (2-4’ x 5-7’), evergreen groundcover that works well under oaks and can provide erosion control to slopes.

The Matilija poppy is a very large species of California poppy. Its flowers alone can grow to 7 inches in diameter. The shrub itself can be 6-10 feet tall and 2-4 feet wide. Plant near other shrubs that can outcompete it for space, such as ceanothus, coffeeberry, sugarbush, or flannelbush. Plant in sandy, well-drained soil and water carefully until established because it can suffer from both too much and too little once. Once established, however, the shrub is easy to grow and requires no watering at all. Can be cut back hard in late fall.

A native, perennial, deciduous shrub with dark green leaves divided into coarsely toothed leaflets. Rose to pink colored flowers containing yellow seeds and grows abundantly in moist soils. Natural habitat for birds and pollinator insects.
