The Staghorn or Giant Staghorn fern is native to the lowland rainforests of north-eastern Australia where it is found growing in the rainforest canopy on tree trunks, tree branches, and sometimes on rocks. It has two types of fronds: the infertile fronds grow upwards, and protect the crown while the fertile forked fronds hang loosely from the base of the crown. Large specimens form a nest which catches leaves and other debris providing nutrients to the epiphytic fern. Large specimens are spectacular in form with attractive light green fronds.

A warm humid environment with filtered light is necessary for the successful growth of these ferns. In home gardens it is commonly grown by tying the crown to a board or by planting in a epiphytic potting mix. In optimal conditions it can reach 6-8 feet in height and width, but the home gardener can expect a plant of about 4 feet high and wide.

It is not winter hardy in Chicago and must be overwintered indoors, although it can be placed outside in a suitable location in the warmer months.
