This took over my flower garden. Was going to pull it but the butterflies and bees love it so I left it alone. No idea what it is, seeded itself.

Hi,
The plant in the photos is Pennsylvania smartweed (Polygonum pensylvanicum). It is a summer annual plant. It will die out in the cold weather. It freely self seeds so will keep coming back if you don't pull it up before the seeds drop.

Here is our webpage on smartweed. http://extension.umd.edu/hgic/smartweed
