Rhaphidophora Decursiva are listed under Leafy Tropical on the Jungle & Loom Plant Care Card. This is a beautiful rare plant that leaves become fenestrated over time.
Ensure that they receive medium to bright indirect light and only water when the top 3 inches of soil are dry. Use well draining/aerated soil (ideally an aroid mix), a pot with drainage. When the soil is dry ensure you thoroughly saturate when you water.
