PROBLEM TO BE SOLVED: To provide a new method for cultivating a moss plant without using cultivation base such as medium culture, and to provide a moss plant decorating body which uses the moss plant cultivated by the cultivating method, and has flexibility in design and easiness of manufacturing. SOLUTION: Stem and leaf bodies of the moss plant are bundled with a proper binder, and crowded moderately to keep the moisture enough for nurturing to artificially form colonies. The artificial moss colonies 2 are appropriately watered to be cultivated. The single or multiple colonies 2 are attached to a decoration base 3a made of ceramic, stone materials, or wood materials with adhesion or other means to form the moss plant decorating body.
