Platycerium holttumii

Genus: Platycerium

Native to the humid forests of Southeast Asia, Platycerium holttumii is a spectacular epiphytic fern renowned for its colossal size and commanding presence. Its rounded basal fronds grow in layered, shield-like clusters, protecting the root base while collecting organic matter and moisture. The long, forked fertile fronds cascade outward like elk antlers—reaching lengths of several feet and creating an unmistakable tropical statement indoors or outdoors.

✨ Key Features

• Architectural Form: Massive, layered shields and long, drooping fronds make it a true showpiece.
• Collector’s Favorite: One of the largest and rarest staghorn species, sought after for its sculptural habit.
• Epiphytic Growth: Thrives mounted on boards or trees, mimicking its natural forest canopy habitat.
• Low Maintenance: Once established, it needs only occasional watering and bright filtered light.

🌿 Care Guide

💡 Light

Prefers bright, filtered light. Avoid direct afternoon sun, which can scorch fronds. Ideal for bright patios, shaded trees, or well-lit indoor spots.

💧 Water

Water by soaking or thoroughly misting when the root base feels dry to the touch. Let it drain well before remounting. In warm months, increase humidity and watering frequency.

🌡️ Temperature & Humidity

Thrives between 65–85°F with high humidity. Protect from frost and dry, heated indoor air. Occasional misting helps mimic its natural tropical environment.

🌱 Mounting & Feeding

Mount on cork bark, tree fern plaques, or wood slabs using sphagnum moss around the root base. Feed monthly during spring and summer with a diluted balanced fertilizer or orchid-grade foliar feed.

🔁 Growth & Propagation

With time, it forms a heavy, multi-layered mound. Mature plants may produce pups that can be carefully separated and remounted once established.
