It defintiely is not rue, the herb planted in butterfly gardens. It has a frilly look.
It looks like a weed. It appears to be in the genus Conyza. There are many, and they look very similar.
Your plant may be pokeweed, Phylotacca americana. It usually has a pinkish stem which I can't see in your pictures. It is not a good plant in garden situations because it spreads laterally via underground roots (rhizomes) as well as by seeds. If I'm correct, the root becomes a large taproot and needs to be dug out completely as well as the lateral roots that are closer to the surface. Birds disperse the seeds after eating the berries so these, like other traditional weeds, show up out of nowhere.
