New spring leaves are reddish
Toxicodendron radicans
DESCRIPTION Poison ivy's most recognizable feature is its three leaflets. These can be smooth edged, toothed or slightly lobed in appearance. This variation can occur within the three leaflets of a compound leaf or a whole plant may appear in one of these forms. This can make identification tricky. The leaves are usually fairly shiny, especially in the spring when they are new and reddish. In the fall they become brilliant yellows, reds and oranges. This perennial plant's habit may be prostrate or climbing. It supports itself using its aerial rootlets to hold on to structures such as trees or buildings. These rootlets make the vine look like a dark brown hairy rope. A mature plant will produce waxy grayish-white berries which are actually eaten by myrtle warblers and tree swallows.
WARNING! Poison ivy can cause an allergic reaction ranging from a mild rash to oozing blisters. All plant parts contain the 'urushiol' oil that causes a reaction in some people. The rash can erupt within a few days or over a week, even sooner for skin that is already irritated. It doesn't really spread and it is not contagious. The "spreading" on your skin is only your body reacting to the allergen over time or possibly re-exposure to any items that have the oil on them.
It is very important to wash anything that came in contact with poison ivy with soap and plenty of water. (Water does not spread poison ivy unless you take a bath with the oil that was on your skin.) This includes clothes, tools, you, your dog, and maybe even your co-worker who never gets poison ivy. The oil on these things will spread to other surfaces and re-expose you. Remember, just because you have never had a reaction to poison ivy doesn't mean you never will.
