The Moss Sedum Retention system design is an effective way of delaying rainwater runoff and adding it to the natural water cycle through evaporation. It’s a drought-resistant, low-maintenance and hard-wearing option. The vegetation consists of flat-growing species of moss sedum that form dense, grassy carpets. The sedum carpet mainly blooms in spring with a predominance of yellow and pink flowers. It features different shades of green for the rest of the year until autumn. In autumn, it then starts to turn red.
