Leatherleaf Fern
Rumohra adiantiformis
The Leatherleaf Fern has deep green, triangular fronds with a thick, leathery texture. It is sturdier than many delicate ferns, which is why florists and indoor growers both rely on it. With enough humidity, the glossy foliage stays full year-round.

Care Notes
Light
Give bright, indirect or dappled light. Harsh direct sun can bleach or burn the fronds.
Water
Water when the top inch of soil feels dry. Keep moisture steady without sogginess. A pot with drainage holes helps prevent rhizome rot.
Soil
Use a rich, peat-based mix that drains well and leans slightly acidic.
Humidity and Temperature
Aim for humidity of 50% or higher with misting, a humidifier, or a pebble tray. In winter, water a little less as growth slows, and keep the plant away from cold drafts and drying heat vents.
Common Issues
Yellow fronds often mean overwatering. Crispy brown tips usually mean dry air. Check leaf undersides for scale insects.
