Cuban Oregano

Plectranthus amboinicus

herb

Cuban Oregano (Plectranthus amboinicus) is not related to true oregano at all but to coleus and Swedish ivy. It is a tender tropical succulent with thick, fuzzy, scallop-edged leaves that carry a potent aroma and flavor of oregano crossed with thyme and a hint of mint. Native to southern and eastern Africa and naturalized across the tropics, it goes by many names - Spanish thyme, Indian borage, Mexican mint. Because it is hardy only in zones 10 to 11 it is grown almost everywhere as a warm-season container plant or houseplant, where its trailing succulent habit also makes it ornamental. A little of the strong leaf goes a long way in beans, meats, and stuffings.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Pepper — Shares the heat-loving, full-sun, lean-and-dry conditions Cuban oregano prefers
• Tomato — The strongly aromatic foliage helps deter some pests in a warm-season bed or large container grouping
• Eggplant — Another tropical heat lover that thrives in the same warm soil and sun

• Mealybugs →

  The most common pest on indoor/overwintered plants - dab clusters with an alcohol-dipped swab and isolate new plants before bringing them in

• Whiteflies →

  Rinse foliage and use yellow sticky traps, especially on plants grown under cover

• Spider mites →

  Raise humidity and rinse leaf undersides; they thrive on dry, dusty indoor plants

🌾 Harvest & storage

Harvest Cuban Oregano by pinching individual leaves or sprig tips as needed once the plant is established; frequent picking keeps it bushy. The flavor is intense, so use it sparingly - a leaf or two replaces a larger amount of true oregano. Use the leaves fresh in bean dishes, meats, stuffings, and marinades; the thick fuzzy leaves do not dry well, so freeze chopped leaves in oil or water if you need to store them.

🥗 Nutrition & benefits

Cuban Oregano delivers a concentrated oregano-thyme flavor used to season beans, meats, fish, stuffings, and marinades across Caribbean, Latin American, African, and South Asian cooking, where it stands in for both oregano and thyme. The aromatic leaves are also brewed into traditional teas. Because the flavor is so strong it is used in small amounts as a fresh seasoning rather than a salad green.
