Background

Chocolate mint is a peppermint cultivar with dark-stemmed, chocolate-brown-tinged leaves and a scent that genuinely reads as peppermint patty. Used in desserts, hot chocolate, iced drinks, and as a garnish. The flavour is more complex than standard peppermint — cooler and sweeter with a lingering cocoa note.

All the same cultural rules as other mints: plant in containers or contained beds; harvest before flowering; cut back after the main harvest flush. Spreads by runners as aggressively as any other peppermint.
