Asplenium trilobum

A small epiphytic spleenwort from the cool temperate rainforests of southern Chile and neighbouring Argentina. It grows on mossy trunks and rotting logs in constantly damp, shady forest, often near streams and waterfalls. It needs cool, humid conditions and will not thrive in a warm house.

Where it grows wild

Epiphytic on mossy stems and on rotten and living trees in temperate rainforest. Specimen labels mention rainforest on steep slopes beside a waterfall, a Fuchsia magellanica and Luma apiculata thicket, and coastal sclerophyll forest near its northern limit.

GBIF records with elevations are all low, from sea level to about 420 m (Contulmo).
