Selaginella heterostachys
A small, creeping spikemoss of warm-temperate and subtropical East Asia, from southern China and Taiwan to Korea, Japan, Vietnam and the Philippines. It grows on damp, shaded banks, mossy rocks and rock walls along forest trails and valleys. It is a good terrarium groundcover that tolerates cooler conditions than tropical Selaginella, given constant moisture, shade and humid, moving air.
Where it grows wild
It grows on wet banks above forest trails, mossy rock faces, soil and rock walls at forest edges, and stream sides in valleys, in broad-leaved evergreen and mixed forest. Most labels describe shade or half-shade, though it also appears on exposed clay roadside slopes at forest margins.
Specimens run from near sea level to about 2,000 m, most between about 200 and 1,400 m, with a median around 600 m.
