I live in Maryland and I have this weed popping up all over my gardens. I haven't been able to identify it using any of the websites, so I'm hoping someone here can. It stands about 10" and has alternating leave stems with serrated leaves that end in a point. The closest I could come to guessing is that it's some kind of mallow? It isn't hard to pull ... it comes out easily, taproot and all.

Thanks in advance for your help!
