Holly Fern
Cyrtomium falcatum
Holly Fern is a sturdy evergreen fern with stiff, glossy dark-green pinnae that look like holly leaves. It handles cooler rooms and moderate humidity better than many tropical ferns. That resilience makes it a practical beginner fern for indoor planters.

Pet Friendly
The Holly Fern is generally considered non-toxic to cats, dogs, and horses.
Care Notes
Light
Medium to bright indirect light works well. Lower light is tolerable; direct afternoon sun can scorch the leathery fronds. North or east windows are good options.
Water
Keep the soil evenly moist without waterlogging. Water when the top inch feels dry, and use a planter with drainage holes.
Soil
A rich, well-draining peat-based mix suits this fern. Repot every 2-3 years to refresh nutrients.
Humidity & Temperature
Moderate humidity is enough for most homes. A pebble tray or light misting helps in very dry winter rooms. Prefer cooler air, about 50°F to 75°F (10°C-24°C), and keep the plant off hot radiators and heater drafts.
Common Issues
Yellow or dead fronds can be cut at the base to tidy the plant. In winter, water less as growth slows.
