Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
I see a flower that is only partially opened. While we wait for more pictures I'll throw out three guesses:
Solanum nigrum
Solanum ptycanthum
Solanum americanum/American Nightshade/Glossy Nightshade - This is the one my neighbors grow as an edible; I grow it but do not eat it myself.
Sunset Zone 28, AHS Heat Zone 9, USDA zone 8b~"Leaf of Faith"
