A second picture. Looks unlike any pepper plant I've seen...

I'm not sure what you have there, but I agree - doesn't readily strike me as a pepper either.

Yeah, not a pepper plant.
I'd just wait and see what it does.

Sorry to inform, but it's a weed, not sure the name, but I pull those out of my garden all the time.

Ugh, thanks everyone for the quick feedback. Fortunately, I still have another seedling that I can transplant. Let's hope it's actually a pepper!

Since we're posting photos of weeds (we call them wildflowers in Texas), here's a couple growing near my garden. I usually let a few various ones go since they attract beneficial insects, but try to yank them before they go to seed...

I think the above is some kind of amaranth. = weed

seysonn,

It is amaranth but we also call it pigweed.

I think the first plant might be a persicaria - some are garden-worthy but the one posted is a weed.
