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
Plant cell quite elongated, and may divide transversely to give a septate appearance. The role of this cell type is to support the plant in axes still growing in length, and to confer flexibility and tensile strength on tissues. The primary wall lacks lignin that would make it tough and rigid, so this cell type provides what could be called plastic support – support that can hold a young stem or petiole into the air, but in cells that can be stretched as the cells around them elongate. Stretchable support (without elastic snap-back) is a good way to describe what collenchyma does.
