Semi–Intensive Green Roofs
Semi-Intensive Green Roof “Heather with Lavender” – The Ideal System Build-up for Blooming Perennials and Aromatic Shrubs
“Heather with Lavender” is a simple-intensive green roof system and allows for the inclusion of various perennials and aromatic shrubs in the plant selection. Compared to extensive green roofs, the larger capacity of the drainage layer and the thicker layer of growing medium facilitate this broader plant palette.
Apart from low-growing Sedum species, the plant community “Heather with Lavender” also contains fragrant drought resistant herbs and small shrubs, like thyme, oregano, lavender and ornamental grasses, which can be completed by colorfully flowering species using a special planting design.
For this green roof, the ZinCo Floradrain® FD 40-E water retaining and drainage element is combined with the ZinCo “Heather with Lavender” system substrate, specifically developed for this plant community to create the right growing conditions for the various species of the “Heather with Lavender” type of Green Roof.
By shaping the substrate layer, it is possible to create a varied appearance. Various designs and combinations with walkways and patios are also possible. The “Heather with Lavender” system requires only moderate care and maintenance. During dry season additional irrigation may be necessary.
