Distribution
This magnificent forest fern which is a favorite of mine was formerly known as Phymatodes scolopendria, does not only grow in the eMalangeni Forest it is widespread in the Old World, occurring from Africa and Madagascar to Asia and Australia, as well as throughout Polynesia.
In Africa umlalamvubu occurs along the east coast of South Africa from as far south as Port St Johns where it occurs mostly in dune forests and dune scrub as well as swamp forest near to the coast. From South Africa its range extends throughout tropical Africa up into West Africa.

Cultivation
Microsorum scolopendria is a hardy species that is often used in landscape design in shady areas and for indoor landscapes. Microsorum scolopendria is easy to cultivate and grows in a wide range of habitats. Microsorum scolopendria when grown outdoors it grows best in light shade, but it will also tolerate direct sunlight for part of the day. In older gardens it often establishes on brick or stone walls, or on trees, especially palms. Although it will tolerate short dry spells it is best kept well watered.
Microsorum scolopendria makes and excellent indoor pot plant.
When grown in hanging baskets the creeping rhizome droop gracefully down from the basket.
This magnificent fern warrants being planted far more often in landscapes and gardens in the areas in KwaZulu-Natal where it grows.
