Hi! I'm new here so I apologize if this plant has been questioned before - I didn't see it in my quick search! We have volunteer tomato plants growing all over our garden due to our compost, and I thought this might be another volunteer vegetable of some sort. Or a happy weed! Thanks in advance :)

Quite young to tell for sure, but it could be pigweed.

agree, and also could be celosia

Thank you!
