Selaginella sibirica
A tiny, mat-forming spikemoss of dry, exposed rock outcrops, ridges and gravels across Siberia, the Russian Far East, Alaska and the Yukon. It is an arctic-alpine plant that freezes solid for much of the year, so despite its listing as a terrarium plant it does not suit a warm, humid tank. It needs full sun, a sharply drained mineral substrate, cool summers and a genuinely cold winter.
Where it grows wild
Dry or exposed rocks and ridges, rocky hillsides, talus, moraine hills and nunataks, often in lichen and moss mats with Dryas, Cassiope and other tundra plants. Some collections are on calcareous gravel, others on shale and phyllite.
GBIF specimen elevations run from near sea level to about 2,040 m; higher sites are more common in the south of the range, low ones in Alaska and the Russian north.
