wild mint family ID help desired!

came across a number of these plants while walking today, in a cow pasture that's been cowless for 6 months or so. it's got a square stem and fairly broad leaves, ~3" across. you can see the flower spikes in the pics. neither of the pics truly capture the color right (phone camera), but there is a shiny blue-purple cast in the center of the leaves. the smell/taste is nice but not super powerful, with a vaguely minty background...but more catnip than mint. it's not the normal catnip i'm more used to, though. any ideas? north carolina appalachian mts.

Howdy Greg! I can't see any pictures. Seems like maybe they didn't post?

apparently not!

Perilla, I think. It’s invasive but edible.  I am not a 100percent sure.

I was gonna say shiso (perilla) as well. It's in the mint family, or as it's called here: the shiso family.

It’s great that this group has people from all over the planet!
