We live on a wooded lot that was partially cleared for our home. One of the succession species that has taken advantage of the available sunlight are winged sumacs. However we have a single example of either Poison Sumac or Smooth Sumac (unless there are other variations I am unaware of in NC). All the information I can find says that Poison leaves are entire and Smooth are toothed as the main way to tell them apart but this example has almost completely entire leaves that show a single tooth or two on either side at the base. The only exception seems to be the last leaflet at the tip which is showing toothing. I have attached pics of the leaf tip above and below. If anyone needs different pictures to help with the ID please just let me know. I have a daughter who loves to be down in our woods with our dogs and would rather she not go through the fun and games of a reaction but equally I understand the Sumacs are great plants for birds so I hate to remove it prematurely. Any help or ideas are gratefully received! Also if anyone knows how I can go about restrict the spread of these via underground runner roots, again I would be glad of the advice. Thanks in advance.
