Could you tell me if this is Poison Sumac? I've never seen it around our yard until this year. I had a horrible rash after pulling weeds a few weeks ago and I'm trying to find the culprit. This was taken in the Southern part of Maryland and we've had a very, very wet summer here. The plant is growing in the form of a small shrub and I'm seeing it everywhere. If it's poison sumac, what's the best way to get rid of it? Any help you could give me would be appreciated. Please feel free to use these pictures.
