Tanner's Sumac Branch
Sumac is any one of approximately 250 species of flowering plants in the genus Rhus and related genera, in the family Anacardiaceae. The dried berries of some species are ground to produce a tangy purple spice often used in juice. Sumacs grow in subtropical and warm temperate regions throughout the world, especially in North America. Sumacs are shrubs and small trees that can reach a height of 1-10 meters. The leaves are spirally arranged; they are usually pinnately compound, though some species have trifoliate or simple leaves.
