Thank you. It is a Herb!

That is one of the most invasive species I've seen in Arkansas. If you have one plant this season, you may have dozens the next . Most southeastern US states consider it a noxious weed.

pull it, I spent a couple hours yesterday pulling it out of containers in the back yard and small garden in the front yard.

I should have mentioned that, although these can get to about 3 feet tall, the ones just 1-2 inches tall often already have flowers and fruit. I think they have a plan for world conquest that involves mad reproduction.

what a nightmare weed ... there is no upside to it ...

once you are given the latin name.. feel free to further research the plant ...

the word herb.. means a lot of things ... hence its hard to answer your question ...

It is spreading like crazy. Seems, my only solution is roundup...

Chickens. Borrow some chickens. Or geese.

do chickens tear up weeds?

They eat weeds that aren't toxic, and some that are questionable. Lol.

Then they'll scratch out a good place for a dust bath.

turkeys wander into my yard and do the dust bath thing, rather annoying as it leaves a dusty hole in the lawn, which they keep making deeper and deeper.
