Bog Moss

This genus consists of about 100 species of bog mosses, found in wet bogs from tropical to Arctic and sub-Antarctic regions. The absorbent sponge-like tissues are important in regulating water loss from various habitats. Decomposed sphagnum is a major component of peat, known for its preservative properties, which has been exploited as a soil conditioner and basis for potting mixes by the horticultural industry. Bog mosses have a long history of use by Eskimos, Lapps, Kashmiris, and Gaelic peoples for absorbent and antiseptic purposes, such as for menstruation, babies' diapers, and as a stable litter. Sphagnum dressings have also been widely used in military field hospitals. Sphagnum japonicum is used internally in a Chinese formula to treat epidemic dysentery. Extracts of decomposed peat moss, such as peat tar and sphagnol, are cheap and effective astringent, antibiotic, and anti-pruritic treatments for skin diseases and irritations.

Dense, clump-forming moss with pale yellow-green foliage, often tinged bright green or salmon -pink. Dark brown fruit capsules are produced in summer.
