We have several volunteers of this plant, most in pots from last year. The plants look hardy and they are growing.
My Apple Plant App is confused! One day it is Salvia, the next it is Bee Balm.
Can anyone help with naming this plant??
Agree with @ljmanning — Looks like a mint. Can be *very* hardy. Very difficult to control/get rid of. https://en.wikipedia.org/wiki/Mentha
Now: Pinch off a leaf and smell.
Next step: Let it flower (if you can) and try ID'ing it again.
My ID app (iNaturalist) suggests Wild Bergamot (part of the mint family) as it's top suggestion, though Spearmint is not far down the list. Lovely shades of green in the photo!
