What Is This Plant?
I don’t know what this plant is. It’s leaves are the spittin-image of giant ragweed, but this one is sprouting from a cut down, 6″ diameter tree stump. Several of these shoots are growing out of the ground right next to the stump, as you can see. I know giant ragweed has been described as a lot of biomass, but I think this is an actual tree, not just a weed. These things grow all over the place – all very large, but I can’t say that I have actually seen a ‘tree’ of this leaf. I will make a point of monitoring them this season to see if they ever develop a seed/flower head.
The closest tree that I could find with some what similar leaves is the sassafras tree. I have lots of short plants that look like sasafras, but these leaves in question are different – they are leaner and have 5 lobes.
A mystery. I do have regular ragweed sprouting all over bull-dozed areas.

I think I just figured it out. Here at http://forestry.sfasu.edu/faculty/stovall/dendrology/index.php/fact-sheets-sp-916/photographs/93-morus-rubra-red-mulberry, it looks like it may be a red mulberry. I grow black mulberries with the rounded leaves, but have never started a red mulberry from seed. Check out the sfasu site, I’m going with Red Mulberry.
