There is an old rhyme that helps identify these pesky plants: "Leaves of three, let it be!" Both of these come in a few different varieties and can grow as shrubs or vines. Poison ivy is found pretty much everywhere except Hawaii, Alaska, and parts of the west coast. Poison oak is found on the West Coast and in the southeastern U.S. More than half the population is allergic to this stuff, which will cause itching and a blistering rash if it gets on the skin. Poison ivy, poison oak, and poison sumac all produce the toxin urushiol.
