Mentha arvensis ( Wild Pennyroyal )
A perennial, reaching up to 2 feet.
Hardy zones 4 to 8.

Mentha piperita ( Peppermint )
A rhizomatous perennial, reaching up to 3.5 ( rarely over 2 ) feet in height, that is native to Europe but has become naturalized over much of North America to as far north as Hearst, Ontario. It is often found in moist to wet meadows and ditches in the wild. It tends to run underground and can become invasive so it is recommended to either contain it into containers or parking lot islands.
The oppositely-arranged, sharply-toothed, ovate leaves are up to 2.5 x 0.5 inches in size.
The leaves are used for flavoring and can be harvested at any time of the growing season.
The tiny, pale purple flowers are borne on dense, upright spikes during early summer to mid-autumn.
Hardy zones 4 to 8.
