Goutweed/Bishop's Weed. Get rid of it fast while you only have a small infestation! Dig deep a bit away from the plant and try to get as much root as humanly possible. Don't leave root pieces or leaves on the ground.

I get it invading from a neighbor and it's a battle.

Thanks duluthinbloomz4, Its not actually mine. It's 2 houses down, but they wanted to know, so I told them I'd post it here.
I'll relay the info.

only 2 houses away ... ????

as noted get rid of it.. before it takes over YOUR garden ... lol
