Polystichum Moss, more commonly known as Hair Cap Moss, is one of the tallest and different looking mosses in the world. Hair Cap Moss takes its name from its distinctive hairs that cap the slender stalks. The strands can start as bright green and change to yellow, orange and red shades depending on the moisture content. The shiny spiked leaves that line the stalks of the moss create a lush green carpet that is excellent for holding soil in place on hillsides to prevent erosion. It grows well in shade and full sun. New growth can be established through transplant existing moss or from readily available spores. This hardy moss will spread quickly and can be cultivated by itself or with other mosses.
