A California native shrub with small white flowers and decorative red berries that turn black when ripe. Hardy, drought-tolerant, and attractive to wildlife.

Why grow it

Coffeeberry offers a native alternative to non-native ornamental shrubs in western gardens, combining wildlife value with low water needs once established. Unlike many drought-tolerant natives, it produces fruit that persists through color changes, extending visual interest across seasons. Its tolerance for both sun and partial shade makes it more flexible than some California natives that demand specific light conditions.

Watch out for

This plant can take several years to reach productive maturity, so patience is needed before substantial berry crops appear. In areas with consistent summer moisture or poor drainage, monitor for fungal issues common to Frangula species, particularly in humid microclimates.
