Poison ivy is a woody vine known for its ability to produce urushiol, a skin irritant that can cause an itchy rash. To avoid poison ivy, you need to know how to spot it: watch out for a plant that has compound leaves with three almond-shaped leaflets and whitish berries. Remember: “Leaflets three, let it be!” Poison ivy is generally light to dark green in color, but it turns bright red in the fall. Its leaflets have a smooth surface and relatively toothless edges.
