What type of tree is this?
I showed this picture to our Hort Agent, Bruce McLean, and based on the picture, he feels that this is a Winged Sumac (Rhus Copallina). It is in the sumac family, but is not poison. If you have any concerns, you are welcome to bring in a sample for Bruce to look at it for a positive identification. We are open 8:30 - 5:00.
