  • Jamaica: In Jamaica, it is often associated with the Maroon culture and is considered a symbol of strength and resistance.


Cultivating the Clamshell Orchid can be a rewarding experience for orchid enthusiasts. Here are some essential care tips:

  • Light: Provide bright, indirect light to mimic the orchid’s natural habitat in the forest understory. Avoid direct sunlight, which can scorch the leaves.
  • Temperature: These orchids thrive in warm to intermediate temperatures, typically between 60°F to 80°F (15°C to 27°C).
  • Humidity: Maintain a high humidity level, around 50% to 80%, to mimic their native tropical environment.
  • Watering: Allow the potting medium to dry slightly between waterings. Water thoroughly when needed, but avoid waterlogging.
  • Potting Medium: Use a well-draining orchid mix, such as fir bark or sphagnum moss. Repot the orchid when the medium breaks down, typically every two to three years.
  • Fertilization: Feed your orchid regularly during the growing season with a balanced orchid fertilizer.
