clearweed?

Thanks, it looks similar to clearweed except for the pronounced serrations on the edges. I’m not sure about amaranthus either, though the leaves look very similar. But I’ve never seen any flowers on it. Whatever it is, it is a notoriously common weed in this area, especially in newly disturbed soil. Thanks for the suggestion!

We have it in Ohio too all over!

Sorry to hear that! :-/ Oh, well—good to know I have company. :-)

Here are a couple more photos in hopes of getting it positively identified, though it seems to have a very characteristic "look" that doesn't show up as well in photos.. I'm just curious as to what it is.

Acalypha rhomboidea? Though that is a plant I've never seen personally so it's just a surmise.

Yes! That's almost certainly it. Thanks again!
