Skunkbush Sumac

Skunkbush sumac (Rhus trilobata), also called lemonade sumac or sourberry, is a broadleaf deciduous shrub in the Anacardiaceae family native to western North America from Saskatchewan and Alberta to Texas, Oregon, California, and Mexico. It reaches 2-8 ft tall with an erect form and produces green-yellow flowers in terminal clusters. It occurs naturally in foothills and canyons on dry rocky soils.

Skunkbush sumac is hardy in zones 3-4 and prefers full sun to shade with moist soil (pH 4.5-6.0) and moderate water. The fruit has a high edibility rating (4/5) and was traditionally used to make a lemonade-like beverage. Possible skin rash is reported but unsubstantiated.
