Plagiomnium maximoviczii

Easy careTerrestrial1–3 cm

Named after the Russian botanist Karl Maximowicz who collected specimens across East Asia, this mat-forming moss grows on the shaded forest floor from central China and Japan to the Russian Far East, where it is locally protected in parts of Siberia. Its leaves curl when dry and spread flat when moist — a natural signal of hydration that makes it easy to read in a terrarium. In its native habitat it grows under dense tree cover where annual humidity exceeds 80% and light rarely surpasses 500 lux, conditions that translate directly to the enclosed microclimate of a closed terrarium.
