Holly Fern
Cyrtomium falcatum
The Holly Fern is a robust, evergreen species known for its tough, architectural fronds. Unlike most ferns that require high humidity and constant misting, Cyrtomium falcatum is remarkably adaptable, featuring stiff, glossy, dark-green pinnae that resemble holly leaves. This species adds a structural, woodland elegance to indoor settings and is well-suited for beginners due to its resilience and ability to tolerate cooler temperatures.

Care Guide
Light
Thrives in medium to bright indirect light. While it can tolerate lower light levels, avoid direct afternoon sun which can scorch the leathery foliage. North or east-facing windows are ideal.
Watering
Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry to the touch. Ensure the pot has drainage holes to avoid root rot from standing water.
Humidity
Prefers moderate humidity levels. While it is more drought-tolerant than other ferns, it benefits from a pebble tray or occasional misting in very dry indoor environments during winter.
Temperature
Prefers cooler environments, ideally between 50°F and 75°F (10°C - 24°C). Keep the plant away from hot drafts, radiators, or heaters.
Maintenance and Seasonal Tips
Remove any yellowing or dead fronds at the base to encourage new growth and maintain a tidy appearance. In winter, reduce watering frequency as growth slows. Repot every 2-3 years using a peat-based potting mix to refresh nutrients.
