Rumohra adiantiformis
The Leatherleaf Fern is a striking, architectural plant prized for its deep green, triangular fronds that possess a unique, leathery texture. Unlike many delicate ferns, this species is remarkably sturdy and long-lasting, making it a favorite for both floral arrangements and indoor gardening. Its glossy, thick foliage provides a lush, prehistoric aesthetic that remains vibrant year-round when its humidity needs are met.

Care Guide
Care Guide for Leatherleaf Fern
1. Watering: Maintain consistent moisture. Water when the top inch of soil feels dry to the touch. Ensure the container has drainage holes to prevent soggy soil, which can lead to rhizome rot.
2. Humidity: As a fern, it loves humidity. Mist regularly, use a humidifier, or place on a tray of wet pebbles. Aim for 50% humidity or higher to prevent leaf browning.
3. Light: Position in bright, indirect light. Dappled sunlight is ideal. Avoid harsh, direct rays which can bleach or burn the fronds.
4. Seasonal Care: In winter, reduce watering frequency slightly as the plant's metabolism slows. Keep it away from cold drafts or drying heat vents.
5. Common Issues: If fronds turn yellow, check for overwatering. Crispy, brown tips usually indicate the air is too dry. Keep an eye out for scale insects on the undersides of leaves.
