Cuban oregano (Plectranthus amboinicus) is a leafy, aromatic plant used both for visual interest and for culinary purposes. Alternative names for this plant include false oregano, Spanish thyme, Mexican thyme and Mexican mint. The leaves possess both strong aroma and taste. Use the leaves fresh and chopped to compliment foods in a similar way as you would use other aromatic herbs, such as sage, rosemary and oregano. I keep my as a house plant as it does not like the cold
Plectranthus genus (Soup mint). This genus consists of around 350 species.
You will need to grow in light gritty very well-drained soil in full sun. Some are tolerant of light frosts but prolonged cold and wet conditions can lead to rotting. Cut back tips in growing season if plants become too straggly.
