Species list for the mulberry genus including some US native ones. https://en.wikipedia.org/wiki/Morus_(plant)

I want to add that, I used the Australian websites from the fact that these sites have numerous great photos and with good information. https://plants.ifas.ufl.edu/plant-directory/broussonetia-papyrifera/

Hi Ron, bot of these are present in the US. Check out these these for more information. Both are native to Asia If it is a Morus, it could be other species as well. But I’m not an expert on mulberry to tell from one species to another… Appreciate for the feedback. Best wishes! https://www.invasiveplantatlas.org/subject.html?sub=6050

Since both suggestions specify this tree/sapling is native to Australia, does it make sense to be found here in Georgia? Thanks.

Link or paper mulberry. https://weeds.brisbane.qld.gov.au/weeds/paper-mulberry

Maybe a type of mulberry saplings(Morus) or a relative in the same family the paper mulberry (Broussonetia ayfera) ? Mulberry has long yellowish roots. Check out a species in the group (the M. alba) images of the last two & one with the leaf underside from the included link below to compare. Flowers are needed to confirm of theses suggestion.
