Natural Habitat & Distribution

  • Geographical Range: Endemic to select tropical regions, where it is typically found in dense, humid rainforests
  • Environment: Thrives in consistently moist, shaded environments with well-draining, organic-rich soils'p refers high humidity and moderate temperatures, conditions that are emblematic of tropical rainforest microclimates

Morphological Characteristics

Leaves

  • Medium-sized, elongated leaves
  • Glossy texture
  • Subtle variegated patterns

Inflorescence (Spadix & Spathe)

  • A modestly sized spathe, often displaying shades that complement the overall foliage
  • Fragrance is generally faint, the structure is typical of Anthurium species and plays a role in attracting specific pollinators

Growth Habit

  • Epiphytic to terrestrial growth habit, often developing on forest floors or attached to tree trunks in humid conditions
  • Utilizes a network of rhizomes to anchor itself and absorb nutrients efficiently

Cultivation & Care

Light Requirements

  • Bright, indirect light, mimicking the dappled sunlight found beneath a forest canopy

Watering & Humidity

  • Regular watering that maintains moist but not waterlogged soil is recommended
