Description Staghorn Fern (Platycerium superbum)

Staghorn fern (Platycerium superbum) is an epiphytic fern native to Australia. A member of the Polypodiaceae family, it's grown for its dramatic, antler-like fronds and unique mounting culture.

Description

Two distinct frond types: (1) Sterile shield fronds—broad, rounded, clasping the mount, turning brown and papery with age, forming a humus-collecting cup. (2) Fertile fronds—long, pendulous, repeatedly forked into antler-like segments, up to 3–5 feet long, gray-green, felted. Spores produced on underside of fertile frond tips. Plant grows as a single, large individual (not clumping like some Platycerium).

Growing Conditions

• Zones: 9–11 outdoors; widely grown mounted indoors.
• Light: Bright, indirect light / dappled shade. Avoid direct sun.
• Mount: Wooden plaque, bark slab, wire basket, or tree branch. Sphagnum moss or orchid mix as base.
• Water: Soak mount thoroughly when dry; allow to dry slightly between. High humidity essential. Mist daily or use humidifier.
• Temperature: 60–80°F (16–27°C); protect from frost.

Care & Maintenance

Feed monthly with diluted balanced fertilizer (1/4 strength) in water. Do not remove brown shield fronds—they protect roots. Remount when shield fronds cover the mount. Propagate from spores (difficult) or by separating pups (rare on this species).

Uses

Mounted on walls, fences, trees, or in hanging baskets. Living art for shaded patios, atriums, and bright bathrooms. Conversation piece.

Potential Issues

Root rot from constant wetness. Scale, mealybugs in shield fronds. Browning tips from low humidity. Requires consistent humidity—challenging in dry indoor air.
