An Australian staghorn

Platycerium superbum, the staghorn fern, is a tender evergreen epiphyte grown for its bold sculptural fronds rather than any flower. It carries the common name staghorn fern and is sometimes still sold under the old name Platycerium grande.

Out of Queensland's canopy

This fern's natural range lies in Australia, in Queensland and New South Wales, where it grows as an epiphyte rather than rooted in soil. Its clumping habit and grey-green shield fronds reflect a life spent clinging to tree bark in that setting.

Warmth, filtered light, humidity

Grown as it would be on a tree, this fern wants a heated greenhouse or conservatory setting out of direct sun, mounted on bark or wood in a mix of coarse leaf mould, loam and charcoal, with bright filtered light and high humidity. Through the growing season water freely and mist daily, occasionally dunking the whole root ball for a few minutes before draining it, and feed monthly; in winter, water is best given sparingly and roots should never be allowed to dry out completely.

Pups or spores

New plants can be raised by replanting the plantlets, or pups, that form at the base, or by growing on from spores.

Two fronds, two jobs

The plant carries a large, upright, kidney-shaped grey-green nest frond that catches falling leaves and insects, which it uses as a slow-release feed. From this base grow the long, pendent, forked, leathery fertile fronds, bright green and wedge-shaped, which are the ones that carry spores.

Largely trouble-free

By the RHS's account this fern is generally free of both pests and disease, which is one reason it suits low-maintenance growing.

Little pruning needed

This is a low-maintenance houseplant that asks for no routine pruning. It is suited to being grown indoors much as it would live in the wild, on a mount rather than in a conventional pot.
