Poison Ivy - Poison ivy (Toxicodendron radicans) is a woody, native vine of North America with 2 to 4 inch long leaflets growing in groups of three leaves. Poison ivy climbs by clinging to any available surface with hairy, aerial roots. The plant produces clusters of ¼-inch, white berries and the foliage assumes bright hues of purple and red during fall and winter. The seeds of poison ivy are spread by birds that relish the fruit. The plant is hardy in USDA Zones 3 to 10 and thrives in areas of full sun and in any soil type. The sap of the poison ivy plant often causes skin irritation and rashes.
