Peperomia japonica

A small, creeping Peperomia from southern Japan, the Ryukyu Islands, Taiwan and southeastern China. Wild records cluster in the warm, humid Ryukyus at low elevations, where it grows in shade under evergreen forest with mild winters and a very wet early summer. It suits a warm, humid terrarium with low light and a mild winter slowdown.

Where it grows wild

Published habitat detail for this species is thin. It is recorded from low-elevation subtropical evergreen forest, where small Peperomia of this kind creep over shaded, mossy rocks, tree bases and trunks in humid, sheltered spots.

Recorded at 17–314 m, median 95 m (15 records with elevations), so it is a lowland and foothill plant.
