Elkhorn Fern
Platycerium bifurcatum
Medium · Some experienceAbout Elkhorn Fern
Platycerium bifurcatum, the staghorn fern, is an epiphytic fern that looks more like mounted antler art than a typical plant. It produces two types of fronds: flat, round shield fronds that attach to trees or mounting boards, and forked, antler-like fertile fronds that extend outward. Native to Australia and New Guinea, it grows on tree trunks in rainforests, gathering nutrients from decomposing debris collected in its shield fronds. Mounted on wooden boards, it becomes a striking living wall sculpture. It needs bright indirect light and regular misting.

History
Platycerium bifurcatum is native to Java, New Guinea, and eastern Australia, where it grows as a tree-mounted epiphyte producing two wildly different frond types in the same plant — a feature called dimorphism. Round shield-shaped sterile fronds press flat against the host tree, catching falling leaves and water to form a nutrient-rich nest, while the antler-shaped fertile fronds extend outward and bear spores on brown felted patches underneath. This arrangement is unique enough among ferns that collectors have prized the species since the early 19th century.
It is typically mounted on wood rather than potted, imitating its natural growth habit. Confirmed non-toxic to pets by the ASPCA. Staghorn ferns have grown on trees for millions of years — fossil records show related species in deposits over 60 million years old.
Indigenous Australians recognized different species and used the large shield fronds for carrying water and food. In tropical gardens, massive staghorn colonies can weigh hundreds of kilograms, entirely engulfing the host tree trunk. The world's most valuable staghorn is Platycerium wandae from New Guinea, with specimens selling for thousands of dollars. In the 1970s, mounted staghorns became a design trend, gracing the walls of modernist homes and restaurants — a trend that has returned strongly since 2020.
Symbolism & meaning
What It Symbolizes
The Elkhorn Fern makes visible courage, growing boldly on bare branches and rough bark with no soil at all. Its very existence is a quiet act of bravery — a fern that has chosen to live where ferns are not supposed to thrive, drawing nutrients from rain, dust, and air. To grow it on a board or in a basket is to honor a plant that decided, somewhere along its evolution, to stop waiting for ground.
- Courage — Growing boldly on bare surfaces with no soil represents bravery and independence
Where the Name Comes From
The name Elkhorn Fern describes its fernlike fronds. Platycerium from Greek 'platys' (flat) and 'keras' (horn), describing the antler-shaped fronds. Bifurcatum means 'twice-forked.'
