![]() | Atlantic Poison-Oak is a low shrub of dry habitats. Fairly common in the Coastal Plain, especially in the Sandhills, Poison-Oak is rare in the Piedmont of North Carolina. All parts of the plant cause severe skin irritation in most people. Atlantic Poison-Oak differs from the very common Eastern Poison-Ivy (Toxicodendron radicans) in that the leaf rachis and petiolules and stems have velvety pubescence. It also only has a shrub form, while Poison-Ivy is normally a woody vine, but can grow like a shrub. Fall color is brilliant orange-red. Chatham Co., NC 9/20/08. |
