The plant is deciduous so after cold weather sets in the stems are leafless and bear only the occasional cluster of berries. Without leaves the stems may sometimes be identified by occasional black marks where its milky sap may have oozed and dried.
The leaves are, composed of five leaflets (occasionally three leaflets, particularly on younger vines) joined at a central point on the leafstalk, and may be up to 6 inches across. The photo below contains both poison ivy and Virginia Creeper leaves.
Not all poison ivy looks the same. Some varieties are much larger and don’t look identical to the common poison ivy leaf. It can be in the form of vines on the ground, on trees and large shrubs. Leaves can be up to the size of dinner plates.
The poison ivy vine has fine hairs anchoring it to the tree while the hairs of the Virginia creeper are coarse.
