This is the largest leaf on our property. iNaturalist identifies it, consistently, as a kind of mulberry. We have a few saplings with this kind of leaf in the back woods, one of which is about 12 feet tall. I have not seen any berries, but the trees are all under a canopy of post oak and cedar elm, so don’t get much sunlight. I’m keeping an eye on them though, and I’ve marked a couple of the smaller saplings for possible transplant to a sunnier location. The idea of mulberry pie is enticing.
