Cuban Oregano (Coleus amboinicus, Plectranthus amboinicus), also known as the Mother or herbs, Mexican mint, or the Spanish thyme, is not genuine oregano. It's also not mint, borage, or thyme. It is, instead, a coleus plant species. This plant, unlike regular oregano, has a short, thick stem and somewhat mushy, serrated leaves. It is semi-succulent, which means the leaves retain some water but not as much as a succulent. The leaves range in length from two to two and a half inches and in width from one and a half to two and a half inches. The plant blooms with pink, purple, or white flowers that attract bees and butterflies from late winter to mid-spring.
Cuban oregano, also known by various names such as French thyme, Indian borage, Indian mint, Mexican mint, and Spanish thyme, is a plant with an unclear history and origin. Although it is most commonly referred to as Mexican mint, it is believed to be native to India. Due to this uncertainty in its background, the plant is known by several different common names.
Mexican mint has strong resistance to disease and is generally not prone to illnesses. However, it can be vulnerable to leaf spots when light and ventilation are poor or when it is overwatered. Its care level is considered easy, since it only needs regular watering and little else. Mexican mint is well suited for people who lack the time and energy to provide consistent care.
How to keep Coleus Amboinicus.
Light
The mexican mint prefers a balanced amount of light, flourishing with moderate sunlight while being able to tolerate stronger sun without harm. It comes from conditions of filtered light, which encourage healthy growth. However, too much or too little light can impede its development and cause it to wither.
Water
Mexican mint, native to semi-arid regions, flourishes in dry conditions and is resistant to drought. It requires only moderate moisture, so watering once a week is usually sufficient. Commonly grown in containers, this plant needs well-draining soil to avoid waterlogging, which helps maintain its aromatic foliage.
Humidity
This plant prefers dry conditions, so don't mist it. However, watering it less often can also thrive in higher humidity.
Temperature
The Mexican mint, native to tropical areas, thrives at temperatures between 68 and 100 °F (20 to 38 °C). In winter it should be kept no lower than 60 °F (15 °C) to prevent cold damage and no higher than 80 °F (27 °C) to avoid heat stress. In summer, it is better placed in partial shade to protect it from high temperatures.
Fertilizer
Mexican mint needs the most fertilizer during its active growth period, which takes place mainly in spring, summer, and early fall. Fertilization is needed to supply essential nutrients the soil may lack, supporting healthy root and stem growth and producing the attractive foliage that is a distinguishing feature of this plant.
Pruning
Mexican mint has aromatic, fleshy leaves and grows quickly. To encourage bushy growth, prune it from early to late spring. This process involves removing leggy stems and dead foliage. Make sure there is good air circulation and sunlight can reach the plant. Also, use clean tools to prevent over-pruning, which can stress the plant.
Pot & Repot
When repotting Mexican mint, choose a pot 1–2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring that the root ball is slightly lower than the rim of the flower pot. Water thoroughly after repotting and place it in a warm spot with indirect sunlight.
Toxicity
Although it is safe for people to eat, Cuban oregano, like other coleus plants, is harmful to cats, dogs, and horses. It may attract your dogs, so consider growing it in a fenced-in area.
