Green Roof Vegetation

Succulents particularly colourful sedums dominate shallow substrate green roofs across temperate europe and north america.

Green roof vegetation.

Founded the first green roof nursery in north america. Vegetative roofs also known as green roofs are thin layers of living vegetation installed on top of conventional flat or sloping roofs. Vegetation and soil act as a sponge absorbing and filtering water that would normally plunge down gutters wash through polluted streets and over tax sewer systems. As the nation s leading supplier of plants for green roof systems since 1998 our accomplished horticulture team has more experience than any other nursery in the united states growing plants for successful green roof projects.

Plants for extensive green roofs should have low growth height rapid growth spreading and fibrous roots that have high drought tolerance. We have chosen to use the word vegetative rather than the word green in this guide because a non vegetative roof could be considered to be environmentally green without being vegetative. Their low growing and or spreading habits great drought tolerance seasonal flowers and contrasting foliage colours textures and forms make them ideal candidates for green roofs. Green roofs mitigate water runoff and sewer overflows.

Succulents such as sedum are often chosen for extensive green roofs because they withstand harsh conditions and minimize water loss. We are active in green roof plant research. Emory knoll farms inc.
