Sedum (Roof Garden Mix) - Create a green roof with Sedum seeds. Green roofs are becoming more and more popular in both rural and urban locations. They can be installed on flat roofs to roofs with a slope of up to 45 degrees. There are different ways of achieving a living roof. An extensive green roof is particularly low maintenance, generally planted with Sedum succulent plants and is designed to look after itself for most of the year. One of the reasons green roofs are becoming so popular is that they offer environmental benefits. Green roof seeds are easy to establish and with the increasing concern about the impact our development of the planet is having on the worldwide environment and the calling for sustainable development, green roofs offer a number of benefits over more traditional forms of roofing, helping to meet sustainable development objectives.
