Hi Jim, thanks for asking. I’m not an expert of both genera, to my eyes the leaves shapes between between mulberry (Morus) & white lettuce (Nabalus) both are lobed, although the mulberry leaves edges are serrated. The OP’s leaves appear to have no serrated margins. I can’t tell from the photo if its main stem/trunk is woody or not. And until there are flowers to confirm, my posts would be always: “Maybe” :). Yes, please post yours after all we love to learn more about plants around us. Thank you Jim & best wishes! Laura

I’ve been seeing a lot of plants with the same or very similar leaf in East Cobb near the Hooch and creeks, but they have a tough, woody stem. The closest thing in appearance to me, other than the leaf shape, are young mulberries. Would this be consistent with the Nabalus? I’ve been puzzled by them. I will revisit the leaf shape of the ones I’ve seen and maybe post my own ID request.

Maybe tall/rough white lettuce (Nabalus altissimus formerly known as Prenanthes altissima)? Check it out and see if you have a match. Best wishes! http://www.missouriplants.com/Yellowalt/Nabalus_altissimus_page.html
