At the Kungens kurva area, just south of Stockholm, 13,000 square meters of green groundcover has been installed on the entrance of a new traffic tunnel. The tunnels are part of an extensive road construction project through Stockholm by the Swedish Transportation Administration, called the E4 Stockholm Bypass. Sempergreen Sedum groundcover was used for both the sloping and curved exterior of the tunnel, commissioned by Skanska Sverige

While the plants provide pleasant colourful views for the drivers, they simultaneously capture CO2 and particulate matter. Compared to grey infrastructure, the green groundcover also provides better drainage, helping to buffer the rain that falls during heavy downpours. The application of more green infrastructure in Stockholm is part of the city's current Environmental Programme, to adapt the city to the changing climate and enhance its biodiversity.  

Low-maintenance, large effect

With the pre-grown Sempergreen Sedum-mix blankets, installation on flat, sloping or curved ground surfaces gives a direct-green effect. Since Sedum is such a tough plant that’s suitable for many different climates, there’s no need for intensive or frequent maintenance, saving time and nuisance.
