Rhus integrifolia (Nutt.) W.H. Brewer & S. Watson
Lemonadeberry, Lemonade Berry, Lemonade Sumac
Lemonadeberry is native to southern California and the northern part of the Baja peninsula. It prefers well-drained chaparral, below elevations of 2953' (900 m).
Plants: A shrub or small tree 3-26' (1-8 m) tall, with a sprawling habit. Inland, they often become trees, but closer to the coast, they often remain low, spreading sideways up to 30' (9.1 m), forming impenetrable thickets.
Leaves: Simple, evergeen, leathery, finely toothed, 1¾-2½" (5-7 cm) × ¾-1½" (2-4 cm). Leaves have a waxy shine above, and are more pale below. They remind me a little of holly leaves.
Flowers: Dense clusters of small, sticky, white to pink flowers. They appear from February to May.
Fruits: Berries are dark red and sticky, up to ⅜" (1 cm) in diameter, and oddly misshapen.
Edibility: Fruits are edible raw or cooked, exuding a sour, lemony flavor. Berry clusters are soaked for 10-30 minutes in hot or cold water to make a drink reminiscent of lemonade. Boiling ruins the flavor, releasing excessive tannins.
