Poison Ivy vs. Virginia Creeper

It is important to recognize Poison Ivy (Toxicodendron radicans) in the field. Poison Ivy flowers from May to July and occurs on a variety of sites and soil types; in both open and wooded areas. Contact with plant parts can cause severe skin irritation caused by an allergic reaction to urushiol. Virginia Creeper or Five Leaf Ivy (Parthenocissus quinquefolia) looks similar, but is not toxic. Both species occur in Oklahoma and are often found together at the same site. Poison Ivy has several growth forms and can occur as a vine or shrub. The leaves may be dark green to almost yellow. Leaves can turn red in the fall.


Skin irritation can occur by direct contact with the plant itself or by handling clothing, shoes, etc. that have touched the plant. There are several over the counter remedies for exposure to Poison Ivy, but more severe cases may require medical attention. Scratching affected areas cannot spread the rash, but may lead to infections. The best strategy is to learn to recognize this species and to simply avoid contact.
