Poison ivy

Asked June 12, 2019, 11:04 AM EDT

The serrated edges of the leaves of this 3 leaf plant have me confused. Is this poison ivy or a look alike?

Hello,

It is hard to tell without seeing a long section of stem that shows 3-4 “groups of three” leaves. Below are references to poison ivy and look-alikes. Cover skin and use disposable gloves, or washable gloves when working around it. Wash all tools and clothing that come in contact with it until you are sure what it is.

If you can protect yourself and pull a section out, and lay it out flat on a plain background for some more pix, that may help me. Also, when it flowers that will really determine what it is. I see some flower buds developing and in about a week you should be able to get clear pictures of them.

Look at boxelder and goutweed pictures- flowers, stem color, how is each group of 3 arranged down the main stem- alternating one at a time, or in pairs opposite each other?
