I apologize for the lack of information. The seedling is in Zone 8a in Starkville, Mississippi. Since it is only a seedling, the bark of the tree appears to be smooth. Please zoom in on the photo to see what you think. I guess this seedling could just be a weed. With my lack of knowledge on this, it is too small for me to know. Thanks!
Sorry, not enough information to identify.
Growing zone, region, size of tree, bark are all important to make an id.
