Sheet moss naturally grows in North American forests on tree trunks, rocks, logs, walls and a variety of other surfaces. In fact, it has been found on all continents with the exception of Antarctica. Moss is a type of plant known as a bryophyte. It has no true roots, seeds, fruits, or flowers. It is so widespread that it also has a number of common names such as carpet moss, rock moss, and feather moss. These names actually describe certain qualities of the moss. It is typically harvested in sheets because of its lateral, thick, and flat growth habit. Sheet Moss prefers shady areas, but it will tolerate partial sun as long as it is not direct sunlight in the afternoon. The plant color ranges from a bright to a medium green to various shades of yellow. It tolerates light foot traffic so it is good for filling in spaces between pavers on walkways and in patios. This moss prefers to grow in slightly acidic loamy or sandy soil. It is also quite tolerant of pollution. In some regions such as the Pacific Northwest, mosses are encouraged to grow as a lawn cover which will do away with weekly mowings. To encourage energy conservation mosses are used on green roofs since they have a reduced weight load compared to higher plants. The mosses are also used as hanging basket linings, as a terrarium soil covers, and even as packing material. Years ago the moss was used as fillings for mattresses and pillows so it is associated with sleep. The genus name Hypnum comes from the Greek word Hypnos, the name of the Greek God Hypnos or sleep.
