Poison Ivy
Danger!
Toxicodendron radicans /Cashew Family

Learn how to identify this plant, it grows everywhere! All parts of the plant contain the rash-inducing oil, so it should be avoided. Remember the saying: "Leaves of 3, leave it be!" Many other plants have 3 leaflets too, so it is important to know the characteristics of Poison Ivy. The middle leaflet is on a long petiole (leaf stem), the 2 lower leaflets have very short petioles. The petioles of the lower leaflets are often a reddish color. The older vines are grayish-brown and hairy. Younger vines have smooth, light brown stems. In the fall the berries are white. I have added this plant in both woodland and roadside catagories because it grows wherever birds drop the seeds! I found this plant blooming in Oak Ridge.
