Overview

Rhus integrifolia, lemonade berry, is an evergreen shrub of the coastal bluffs and canyons of southern California and Baja California, usually 3-10 feet (0.9-3 m) tall but reaching 30 feet (9 m) as a small tree in sheltered sites. It forms a dense, rounded mound of stiff branches clothed in leathery, dark green leaves that are oval, 1-2.5 inches (2.5-6 cm) long, flat or slightly folded, and sometimes toothed. Clusters of small pink to white flowers open from winter into spring at the branch tips. These give way to flattened reddish berries coated in sticky, glandular hairs and a tart, acidic film; soaked in water they make a lemonade-like drink, the source of the common name. The shrub tolerates drought, salt spray, and poor soils once established and resprouts after fire from a woody base. It is sensitive to hard frost and is damaged below about 20F (-7C), which restricts it to mild coastal and near-coastal gardens. Its eventual width and dense growth call for room and occasional thinning.

Native Range

Native to the coastal sage scrub and chaparral of southern California and Baja California, Mexico, mostly within a few miles of the ocean. It grows on bluffs, canyon slopes, and dunes.

Suggested Uses

Used for informal screens, clipped hedges, bank stabilization, and habitat plantings in coastal and dry-climate gardens. It suits seaside sites for its salt tolerance and serves in fire-resprouting native landscapes. Its size suits larger spaces or hedging rather than small beds.

How to Identify

Recognize it by leathery, flat or slightly cupped evergreen leaves that are oval with entire or finely toothed margins, darker and duller than the folded leaves of the related sugar bush Rhus ovata. Dense clusters of pink-tinged buds open to small pale flowers in late winter. The fruit is a flattened, sticky red berry with an acidic coating.

Care & Maintenance

Care Guide

Rhus integrifolia grows in full sun to light shade on well-drained soils, including sandy, rocky, and clay ground, and tolerates salt wind. Once established it needs little or no summer water and rots if overwatered in heavy soil. It withstands hard pruning and resprouts from the base, which makes it useful for clipped hedges and screens in mild climates. Frost below about 20F (-7C) burns the foliage, so it is grown only in low-frost areas. It needs no feeding in native soils. Berries and leaf litter drop beneath the canopy.

Pruning

Prune after flowering to shape the shrub, thin crowded branches, or maintain a hedge, since it tolerates hard cutting and resprouts. Take out frost-damaged growth once new shoots appear in spring. Little routine pruning is needed for an informal form.

Toxicity
