Poison Sumac Berries

Poison sumac produces small, round berries that grow in clusters on the stem of the plant. The berries start out green and may turn white, yellow, or cream-colored as they ripen. The berries are typically about ¼ inch in diameter and have a smooth, waxy surface. Unlike poison ivy and poison oak, the berries of poison sumac are not considered toxic and are not a source of urushiol, the toxic oil that can cause a rash. However, it's still important to avoid contact with the plant and its leaves and stems, as they do contain urushiol and can cause a painful rash if touched.
