Pyrrosia assimilis

A small creeping felt fern widespread in the hills of southern and central China, growing on rocks and tree trunks. Its thick, hairy fronds handle drying spells well, so it suits a mount or an open mix with bright shade, hot humid summers and a cool, drier winter.

Where it grows wild

Grows on shaded rocks, rock walls and tree trunks in subtropical evergreen forest and along streams; like other Pyrrosia it is drought-tolerant thanks to leathery, star-haired fronds.

Recorded elevations 400 to 1150 m, median about 515 m; most measured sites are lower, 90 to 320 m.
