Sphagnum very important soil and topper for most carnivorous plants. In the 7th Framework Programme Mossclone peat mosses multiplied in moss bioreactors are developed as a new tool to monitor air pollution. Sphagnum is also used in air layering, a method of propagation used to propagate woody stems like guavas. A ball of Sphagnum is tied against a midway ringed bark of a branch still attached on the parent plant using a translucent plastic material (vitalon). Native Americans used peat moss as diaper material for their babies and is used to wick away the moisture and absorb the excrement from the
Moss in cities. Examples would be "Rhytidiadelphus squarrosus", a garden weed in Vancouver and Seattle areas; "Bryum argenteum", the cosmopolitan sidewalk moss, and "Ceratodon purpureus", red roof moss, another cosmopolitan species. A few species are wholly aquatic, such as "Fontinalis antipyretica", common water moss; and others such as "Sphagnum" inhabit bogs, marshes and very slow-moving waterways. Such aquatic or semi-aquatic mosses can greatly exceed the normal range of lengths seen in terrestrial mosses. Individual plants or more long are common in "Sphagnum" species for example. Wherever they occur, mosses require liquid water for at least part of the year to complete
