Pyrrosia porosa is a little-known tongue fern species with a wide native range from India, across southern China and into the Philippines, where it can be found growing on tree trunks from 3,000' to 8,500' elevation. The thick, dark green, 10" x 1.5" evergreen fronds emerge from a tightly clustered rhizome. The brown indumentum on the leaf back adds a lovely contrast to the dark green fronts. In marginal winter climates, Pyrrosia porosa should be planted on a well-draining slope, and in colder climates, it makes both a superb pot specimen or hanging basket.
