Abstract
A flexible hygroscopic mat of low weight per unit volume for the landscaping of surfaces, such as the roofs of buildings is provided. Such mat comprises a rock wool mat having a thickness of approximately 2.0 to 3.5 cm and weight per unit volume between approximately 30 and 80 kg/m.sup.3 that enables it to be rolled up and living plants having roots that provide mechanical strength to the overall hygroscopic mat to form a finished product that is capable of being unrolled and applied to a roof or similar surface. The hygroscopic mat while rolled up can be readily transported to the site where it is to be installed. Also, commonly no further landscaping is required once the flexible hygroscopic mat is placed on a roof or similar surface.
