Plectranthus amboinicus is a distinct, aromatic herb highly valued in various global cuisines, particularly across the Caribbean and parts of Asia. Although not a true oregano, this plant is part of the mint family (Lamiaceae) and shares a similar pungent fragrance, making it a popular culinary substitute in tropical and subtropical climates. Characterized by thick, velvety, semi-succulent leaves, it is a fast-growing perennial that thrives in intense heat. Its strong, unique flavor profile, often described as a blend of oregano, thyme, and sage with a hint of menthol, makes it a sought-after addition for flavoring meats, stews, and stuffings.
What Exactly Is Cuban Oregano
Plectranthus amboinicus is commonly confused with true oregano, Origanum vulgare, but is easily distinguished by its physical form. Unlike the small, flat leaves of its namesake, Cuban oregano features fleshy, gray-green leaves covered in fine, soft hairs, giving them a fuzzy, almost suede-like texture. These succulent leaves allow the plant to store water.
The herb’s potent aroma intensifies when the leaves are crushed and is often described as having notes of camphor or menthol. This strong scent has earned it several regional aliases, which are important to know when searching for the plant. Depending on the location and vendor, you may find it listed as Spanish thyme, Mexican mint, or Indian borage. The plant’s spreading, mounding habit and square stems are typical features of the Lamiaceae family.
The Best Places to Purchase This Herb
Acquiring Cuban oregano often requires looking beyond standard garden center selections. Online herb nurseries and specialty plant vendors are reliable sources for purchasing a live, potted plant. When searching these sites, use the scientific name, Plectranthus amboinicus, in addition to common names like Spanish thyme or Mexican mint to broaden the search results.
The herb is also frequently sold as unrooted or rooted stem cuttings, which are easy to ship and propagate. Platforms specializing in handmade goods or small-scale gardening supplies often feature sellers offering fresh cuttings. Buying a cutting is often the most economical way to start your plant, as it roots easily in water or moist soil.
For local acquisition, check farmers’ markets and community garden groups, as enthusiasts often trade or sell cuttings of plants that are difficult to find commercially. Local garden centers in regions with large Caribbean or Latin American populations may also stock the plant. Asking about Plectranthus amboinicus specifically can help vendors locate it, even if they do not recognize the name Cuban oregano.
Post-Purchase Care and Maintenance
When you bring your Cuban oregano home, place it in an area that receives bright, indirect sunlight. While it can tolerate some morning sun, protect it from intense afternoon exposure, which can scorch the fleshy leaves. Because of its semi-succulent nature, this herb requires well-draining soil to prevent root rot.
A sandy potting mix or one formulated for cacti and succulents works well. Watering should be infrequent but thorough; allow the top inch of the soil to dry out completely between waterings. Overwatering is the most common cause of plant failure, so err on the side of underwatering.
Cuban oregano is a frost-tender plant. Gardeners in cooler climates must grow it in a container so it can be easily moved indoors before temperatures drop below 40°F. When overwintering indoors, place it near a sunny window and reduce watering significantly until spring.
