Chocolate mint (Mentha × piperita f. citrata 'Chocolate') is a peppermint cultivar, not a distinct species. It produces the typical peppermint flavor with a secondary note that many people describe as chocolate or cocoa — likely from linalool and linalyl acetate compounds that give the leaves a rounder, less sharp flavor than standard peppermint.

Whether you find it genuinely chocolate-flavored depends on expectation. It does not taste like a chocolate bar. It tastes like peppermint with a floral, less sharp quality. It is useful as a culinary herb in desserts, beverages, and cocktails.

Like all mints, it spreads aggressively by underground rhizomes.

Zones and cold hardiness

Per Missouri Botanical Garden, Mentha × piperita cultivars are hardy in USDA zones 5–9. They die back to the roots in zones 5–6 and grow as perennials with minimal dieback in zones 7–9. In zones 3–4, winter mulching (3–4 inches of straw or wood chips) over the root zone is recommended for overwintering.

Per Penn State Extension, chocolate mint emerges in early spring as soil temperatures reach 40°F, typically in March–April in zone 7.
