Plectranthus amboinicus: Aromatic Mexican Mint for Foliage and Culinary Use

Mexican Mint (Plectranthus amboinicus), also known as Cuban oregano, is a spreading evergreen perennial prized for its thick, aromatic, succulent-like foliage. Grown as an annual in cooler zones or as a houseplant, it reaches 6–12 inches tall but can spread 3–6 feet wide. Tubular lilac-pink, mauve, or white flowers appear in summer, though the foliage is the main attraction. This fast-growing plant thrives in dappled shade with moderately fertile, well-drained soil.

Growing Conditions

Outdoors, provide dappled shade and well-drained soil. Indoors, place in bright light but protect from hot afternoon sun. Keep just moist in winter. Propagate easily by division in spring or stem-tip cuttings anytime. Seed can be sown at 66–75°F when ripe.
