Origin
Native to the tropical regions of northern South America and parts of the Caribbean, where it thrives in humid, shaded environments.

Light
Prefers bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Suitable for placement near east or north-facing windows.

Water
Maintain consistently moist soil, allowing the top inch to dry out between waterings. Reduce watering frequency during the winter months.
