In late March we took our first clients for the season to Loches. As we strolled passed the souvenir shop / café on our way to the Logis Royal we noticed they were installing a green roof. The café wasn't open - too early in the year for most tourists. While they were closed they had a team of gardeners working on the roof.
There were barquettes of Stonecrop stacked on the pavement. The plants were hoisted up to the flat roof on a lift and positioned by the men up there. Several Stonecrops are native to here and will colonise walls and roofs for themselves, so these plants will thrive up in their new home.
You can't see it from the ground at all, but it is nice to know it is there. I have a hankering to create something similar for a carport on our front courtyard. This installation, right in the heart of an historic monument, gives me hope that I might get permission to install one here eventually.
