    Staghorn ferns are a group of about 18 species of epiphytic ferns in the genus Platycerium of the polypod family (Polypodiaceae) native primarily to Africa, Australia and Southeast Asia, whose fronds supposedly resemble the forked antlers of male deer or elk.

    The names “staghorn fern” and “elkhorn fern” are often used interchangeably, although those with thinner fronds are often called elkhorn ferns.

    P. bifurcatum is the species most commonly cultivated as an ornamental plant, since it is probably the easiest to grow. Native to rainforests of Java, New Guinea and southeastern

    Australia, it does best with year-round temperatures above 40°F, so it can only be grown in gardens with a very mild climate (zones 9 and above) or as a house plant that can be moved outdoors during the summer. It has naturalized in Florida and Hawaii, where it is considered an invasive species on the islands. Staghorn fern makes a great ornamental adornment for a wall indoors or seasonally outdoors in the Midwest. This species was given the Royal Horticulture Society’s Award of Garden Merit in 1993.
