How Do You Identify Poison Sumac?
Each leaf of a poison sumac plant has clusters of seven to 13 smooth leaflets arranged in pairs. Poison sumac lives in wet, swampy regions in the Northeast, Midwest and parts of the southeast U.S.
A full grown poison sumac tree can be as tall as 20 feet. This tall tree has drooping clusters of pale yellow, cream-colored or green berries. The sumac is nonpoisonous when they have red, upright berries. You will not get any allergic reaction from contact with sumacs.
