This 8500 sf, un-irrigated green roof looks very fine!The only 3 inches of soil with a plastic drainage sheet allow different Sedums species to grow well (Especially S. Sieboldii, S. Cauticola..).
Here the planting design is based on different colorful lines; which are still perfectly visible after 4 years. A yellow/white and a blue/gray one. Sedums flowers (Sexangulare, Album) and leaves (Cauticola, Sieboldii, ..) give to this roof a very interesting and unusual stripes aspect. I like it!
To preserve this design and to prevent the high weed pressure (mostly clovers), a relatively good level of maintenance is required. But without any water and with a shallow media, the coverage is excellent and people from the surrounded (Hotel clients) can admire this original roof!
Much more nicer than a conventional one, isn't it?
