Poison Sumac

In the United States, poison sumac grows in standing water in peat bogs in the Northeast and Midwest and in swampy areas in parts of the Southeast. Each leaf has clusters of seven to 13 smooth-edged leaflets. The plants can grow up to 15 feet tall. The leaves are orange in spring, green in summer, and red, orange, or yellow in fall. There may be clumps of pale yellow or cream-colored berries.
