I don't think it's datura. It reminds me of turk's cap, but not quite the same. Maybe a hardy hibiscus?

It does resemble my jimsonweed "new leaves" and that little tiny one bottom left looks like a mini regular leaf, lol

How big is the plant? All of the water and clouds have made a lot of my plant leaves look *different*

Time will tell, hehehe

It looks like some variety of nightshade to me.

Maybe, all of mine have narrow leaves but there are certainly more varieties than I have, lol

There are two plants in the photo. They are about a ft tall. The largest leaves are 3 in long. Jolana, you made me go out there with flash light to make sure the little plant is a weed ... lol

Anyway, thank you all for your ideas. I guess I'll let it go a little longer to see if it does something interesting, like make a flower bud. Flowers pretty much nail down an ID ... :-)

Possibly clammy ground cherry - look at leaves for Physalis heterophylla.

We've had another native ground cherry species show up for the first time this year.

Okay, went out with the flashlight again ... LOL. The leaves certainly looks like it. However, the stems are perfectly smooth, but I think it's safe to say it is of that family, another member of the nightshade family. Thanks Bostedo! Seems with the rain and wind we are getting lots of volunteers we've never had before. I'm on the edge of some fields and woods so no telling what's out there.

Is it any closer to showing what it is?

I was satisfied that it was one of the wild nightshades and didn't have the space or inclination to let it grow to flowering size for a positive ID as to the variety. I pulled it.
