Peat moss



Peat moss, moss (genus Sphagnum) that grows and accumulates on the surface of freshwater marshes in Canada, northern Europe, and Siberia. Peat moss grows up to 20 in (50 cm) high, forming a spongy mat without true roots. Its ability to absorb and hold water makes it commercially useful as a mulch (soil covering to prevent drying). It is also used as a growth medium for mushrooms and orchids and as a packing material.
