My wife found this growing earlier this summer, and at first didn't think much of it other than it looked good going up the side of our Mountain Ash in our front yard. It suddenly dawned on me and the plant got taller, that it might be poison ivy, because the leaves are arranged in goups of three. I took the photos, and you may publish them anywhere you wish. We live in Rosemont, Ill. between O'hare Airport and Chicago. The plant is now about two feet tall, and climbing. At first I thought is was a small tree growing, but now I am very suspicious of the plant.
