What is this plant / weed? [see photos below]
It's about 6+ feet tall now, though I'm guessing most people don't let them grow this tall.
This is growing currently (August, 2020) in northwest Ohio.

It is a stinging nettle (Urtica dioica), be careful not to touch it. It can sting you and that will burn and itch very bad.
It is not native to your area, it is an invasive species.
If you have a lot and you think they grow on clean soil, you can consume them as tea or soup. Of course wear gloves when harvesting them.
