Platycerium madagascariense

As the name suggests, this staghorn fern (Platycerium) originates from Madagascar. It grows in the northeast of the island on tall trees of the genus Albizia . It appears to occur (almost?) exclusively on a single tree species, Albizia adianthifolia . Fortunately, this is not necessary to replicate in cultivation to successfully grow the plant.

Platycerium madagascariense is the smallest member of the genus. It usually reaches a diameter of about 15 to 20 cm, rarely up to 30 cm. It does not grow in lowland areas but at altitudes of 400 to 1100 m above sea level and therefore prefers milder temperatures to scorching heat.

It produces two different types of leaves. First, there are the normal fronds, which in older plants bear spores; second, there are the so-called "mantle fronds." The fronds of P. madagascariense are simple, with one or two forks and rounded tips. The mantle fronds protect the rhizome and roots and have conspicuous bumps, making it one of the most attractive staghorn ferns. Older mantle fronds die and turn brown, but remain attached to the fern.

These elevations likely provide habitat in nature for ants, which nest under the mantle leaves.

It grows best when mounted or attached sideways to a substrate such as cork. This allows it to develop the shape it naturally acquires. This species should always be kept slightly moist and requires high humidity. We therefore recommend it for plant cabinets or terrariums, but not as a houseplant.
