  • Inflorescence is visually striking, and it is pollinated by small insects attracted to the shape and color of the spadix and spathe

Growth Habit

  • Terrestrial species, growing from a rhizome. It has a compact, upright growth habit and does not climb or trail

Cultivation & Care

Light Requirements

  • Direct sunlight may scorch the leaves, so filtered light is ideal

Watering & Humidity

  • Keep the soil evenly moist but well-drained. Ensure that the plant does not sit in water to prevent root rot
  • Requires high humidity (above 60%) for optimal growth. Regular misting or a humidity tray will help maintain proper moisture levels

Soil & Potting Mix

  • A well-draining, organic-rich potting mix is recommended. A mixture of peat, perlite, and orchid bark provides the necessary drainage while retaining moisture

Temperature & Fertilizer

  • Best grown in temperatures ranging from 22°C to 28°C (72°F to 82°F). Avoid exposure to temperatures below 18°C (64°F)
  • Apply a balanced liquid fertilizer once a month during the growing season. Reduce fertilizing during the winter months when the plant is not actively growing
