Does it have stickers? Might be blackberry. Put 2 walmart bags over your hand and pull the plant out, then pull the bag over the plant and tie a knot in the bag.

Thank you! I will try that in the morning!

You have to taste it to see. :-)

So far, it does not look like poison ivy to me.

No, it is not poison ivy. It is a small tree which has been chopped back and is resprouting. I'm thinking Acer negundo.

Thank you!
