Natural Habitat & Distribution

  • Geographical Range:  Indigenous to tropical regions of Southeast Asia, where it flourishes in the humid understory of rainforests.
  • Environment: Thrives in high-humidity environments with well-drained, organically rich soils and a warm, stable climate that mimics its native tropical forest conditions.

Growth Habit

  • Exhibits a clumping
  • Terrestrial growth habit
  • Rhizomatous structure that supports moderate spread in a cultivated setting

Cultivation & Care

Light Requirements

  • Bright, indirect light
