Staghorn Fern

Platycerium bifurcatum

Also known as: Elkhorn Fern

A striking epiphytic fern with two types of fronds: rounded, shield-like basal fronds that hug a mounting surface, and long, antler-shaped fertile fronds that fork like a stag's horns. Traditionally grown mounted on wood rather than potted.

Watering amount

How much water does my Staghorn Fern need?

350 ml

per watering session

large pot — Medium pot (10-20cm), medium indirect light, spring/summer active growth

Estimated guideline, not a precise measurement — scale up for larger pots, brighter light, or active growth; scale down for smaller pots, lower light, or winter dormancy. Always water until it drains from the pot's base rather than measuring exactly.

Watering guide

Season note

Soak (mounted plants) or water thoroughly (potted) about once a week, letting the mount/medium dry out somewhat between waterings; mist fronds a few times a week for humidity.

Overwatering signs

Blackening at the base, root/frond rot

Underwatering signs

Wilting, curling fronds

Plant care guide

Staghorn fern, botanically Platycerium bifurcatum, is native to eastern Australia (Queensland and New South Wales), New Guinea, Java, New Caledonia, and Norfolk Island, where it grows exclusively as an epiphyte, attached to the trunks and branches of larger trees in humid subtropical and tropical forest habitats. It belongs to the fern family Polypodiaceae, within the genus Platycerium, which comprises roughly 18 recognized species distributed across tropical regions of the world; Platycerium bifurcatum is by far the most widely cultivated and commonly available species in this genus, prized specifically for its comparative ease of care and propagation relative to its rarer, more demanding relatives.

The plant's most distinctive and immediately identifiable feature is its two structurally and functionally different types of fronds. Basal fronds — also called shield fronds or nest leaves — are flat, rounded, sterile structures that press directly against the surface of a host tree (or, in cultivation, a mounting board or container), starting out green and gradually turning brown and papery with age; these fronds serve a genuinely important dual function, anchoring the plant securely to its support while also curving slightly to trap falling leaves and other organic debris, which decomposes over time to provide the plant with a self-renewing source of nutrients despite having no soil-based root system to draw from. The second frond type, the fertile fronds, are the plant's true visual signature: elongated, deeply forked, antler- or stag-horn-shaped structures, covered in a fine, felty, silvery-white coating of protective scales, that can grow up to three feet long and give the species both its common name and its equally popular alternate name, elkhorn fern.

Frequently asked questions

Is Staghorn Fern safe for cats and dogs?+

Yes, it's non-toxic to pets and humans, making it a safe unusual statement plant for pet households.

How do I water a mounted Staghorn Fern?+

Soak the moss/root ball in room-temperature water for about 20 minutes once a week (or run it under the sink), then let it drain fully before rehanging.

Can a Staghorn Fern grow in regular potting soil?+

It's an epiphyte and prefers being mounted or grown in a very loose, well-draining orchid-style medium — traditional dense potting soil tends to stay too wet and cause rot.
