Poison ivy (Rhus radicans L.) is a woody perennial, reproducing by seeds and creeping root stalks. It is found in rocky fields, pastures, fence rows, on roadsides, railroad embankments, under telephone lines, and in rich alluvial woodlands. Poison ivy is native in Iowa and widespread throughout the United States and Canada. Earliest mention of poison ivy was made by Captain John Smith in 1609. J. P. Cornut described the plant in his work on Canadian plants in 1635. It has been shown that as many as 26 different kinds of birds arc responsible for the wide dissemination of poison ivy.
