Mentha x villosa
This is the real thing. This is THE mint used in Cuba where the Mojito drink originated and it tastes great! Mojito mint can be used in other dishes and refreshing drinks where it imparts a sweet, fresh lime-minty flavor.
Grow in full-part sun. Moist-average soils. All mints spread aggressively so grow in a pot if this is a concern, otherwise let it ramble for a plentiful source of fresh mint! Zones 5-9.
