    Multiflora rose was introduced into the eastern United States in 1866. It is native to eastern Japan, China, and Korea. It was introduced into the U.S. to act as a “living fence” for farmers to use to keep their cattle maintained and also to help in erosion control. 

  • Poison Ivy (Toxicodendron radicans)

    Family: Anacardiaceae

    This plant can be found nearly anywhere in the continental United States. In Ohio, it usually grows as a woody vine that climbs up a tree trunk. But it can also spread along the ground, especially in the vicinity of an established vine.  The roots of the vine grow under the ground and often sprout up to form to what look like new plants.
