  • Ideal Temperature: 22–30°C; highly sensitive to cold below 18°C
  • Watering: Keep soil evenly moist but not soggy; never allow the plant to fully dry out
  • Pet/Child Safe: Toxic (genus level) — contains insoluble calcium oxalate crystals that cause severe burning, irritation, and swelling in the mouth and throat if ingested by pets or humans
  • Soil Type: Light, airy aroid substrate with bark, perlite, and coco coir
  • Propagation: Rhizome division; handle carefully, as the plant is delicate
  • Eventual Height and Spread: 25–35 cm tall; 20–30 cm wide
