I'm also a mint fan, I grow them between my barn and the gravel driveway, so pretty self-patrolling re unwanted spread and creates a softer appearance. I have many of the same as well: apple, spearmint, chocolate, mojito, orange, pennyroyal. Plus lemon catnip, also relegated to the gravel bed. When I had a small preformed open pond, I also had a water mint - I was hesitant to introduce that to my farm pond, fearing it might be invasive, so it went away when we filled in the pond with rocks and some bubbler columns.
