How can I tell the difference between poison ivy and poison oak?

Asked November 3, 2014, 4:09 PM EST

Hello,

I have a person asking what how they can tell the difference between poison ivy and poison oak. Also, are there 2 types of poison ivy? One with 3 leaves and one with 5? Where is a good resource to get pictures of both ivy and oak?

Thank you,

Shelly

The good news is; there is no poison oak in Michigan. Poison Ivy can be tricky to identify because the individual leaflets can vary some from plant to plant, and there are several look- alikes. The following sources will help with the identification of poison ivy and poison oak. The plant with five leaflets is most likely Virginia Creeper, a nontoxic native vine. Poison ivy never has 5 leaflets. When Virginia Creeper is first getting its leaves, two of the leaflets can be very small making it look a lot like poison ivy. When in doubt follow the old saying; leaves of three let it be.
