Poison Ivy
This plant is identifiable by three waxy looking leaves about 2 to 5 inches long. If you were to cross your hands at the wrist, those are the two bottom leaves. For the middle leaf place both your hands on top of each other. Poison ivy can look like a shrub, a small plant or a vine crawling up a tree. The vine will be hairy, do not touch the hairs as they also have poison ivy oil on it.
