Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
This is only a guess and I hope I am wrong, but if it's Stick-tight Desmodium cuspidatum, Fabaceae (or similar) it's a bad thing.
I voluntarily go into my neighbors' yards to pull these up so they won't spread.
Sunset Zone 28, AHS Heat Zone 9, USDA zone 8b~"Leaf of Faith"
