What is California Coffeeberry?

California Coffeeberry, also known as California Buckthorn, is an evergreen shrub native to the western United States, primarily found in California, Oregon, and Arizona. It belongs to the Rhamnaceae family and can grow up to 15 feet tall and wide, although it typically reaches a more modest size of 6-8 feet.

The plant features glossy, dark green leaves that are 1-3 inches long and have smooth edges. In the spring, small, inconspicuous flowers bloom, followed by berries that start green and turn red and then black as they mature. These berries are a favorite among birds and other wildlife.

How to Grow California Coffeeberry

Planting

The best time to plant California Coffeeberry is in the fall or early spring, although it can be planted year-round in mild climates. Choose a location with well-draining soil and full sun to partial shade. Dig a hole twice as wide as the root ball and just as deep. Remove the plant from its container, loosen the roots, and place it in the hole. Backfill with soil and water thoroughly.

Watering

California Coffeeberry is drought-tolerant once established, but it needs regular watering during its first year. Water deeply and infrequently, allowing the soil to dry out between waterings. After the first year, the plant can survive on rainfall alone in most areas, but it may need occasional supplemental watering during prolonged dry spells.

Fertilizing

California Coffeeberry does not require regular fertilization. If desired, you can apply a slow-release, balanced fertilizer in the spring, following the package instructions.

Pruning

Pruning is not necessary for California Coffeeberry, but it can be shaped or trimmed to maintain its desired size and form. The best time to prune is after the plant has finished fruiting, typically in late summer or early fall.

Pests and Diseases

California Coffeeberry is relatively resistant to pests and diseases. However, it can occasionally be affected by scale insects, aphids, or powdery mildew. These problems can usually be controlled with horticultural oils, insecticidal soaps, or fungicides.

Propagating California Coffeeberry

California Coffeeberry can be propagated by seed or cuttings. To propagate by seed, collect the berries in the fall and remove the pulp. Sow the seeds in a well-draining seed-starting mix and keep them moist until germination occurs, which can take several months.

To propagate by cuttings, take 4-6 inch stem cuttings in the summer and remove the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the cuttings moist and in a warm, shaded location until they develop roots, which can take several weeks.

Using California Coffeeberry in the Landscape

California Coffeeberry is a versatile plant that can be used in a variety of landscape settings. Here are a few ideas:

• Hedges and Screens: Plant California Coffeeberry in a row to create a dense, evergreen hedge or screen for privacy or to define areas of the garden.
• Background Plantings: Use it as a backdrop for smaller, colorful plants or to fill in gaps in the landscape.
• Slopes and Erosion Control: The deep roots of California Coffeeberry help stabilize soil on slopes and prevent erosion.
• Wildlife Gardens: Include it in a native plant garden or wildlife habitat to provide food and shelter for birds and other animals.
