Native to a wide range across much of the western U. S and parts of Canada and Mexico. Rounded, open to dense habit. Medium to bright green, 2-3 long leaves divided into 3 oval, toothed to deeply-lobed leaflets. Central leaflet is fan-shaped and larger than the two side leaflets. Vibrant autumn color. Leaves have a somewhat unpleasant odor when crushed. Small clusters of yellow-green flowers appear before foliage in spring. Clusters of small red, hairy, sticky, flattened-oblong berries. Source of food and cover for birds. Good for natural hedges, screens, or background planting. Minimal pruning. May spread by suckers. Several cultivars available including prostrate varieties. Sometimes confused with Poison Oak. Synonym: Rhus aromatica trilobata.
