I bought this plant last year and is doing well in a pot. Want to know where exactly the identity ofthis belongs? I like the lovely smell of this peppermint.

I think it looks like Wild Mint, Mentha canadensis.
Field Mint (Mentha canadensis)

Thanks Christine. It looks like it. There are some images posted where the flowers are at the tips of branches.

Your plant is very pretty. You should add your images to the database.
