Green Roof

Spotted this shed in a nearby garden. The large variegated plant on the left of the picture is actually behind the shed, but I don't think it will be long before it finds it's way to join it's fellows on the roof. I would like to think it is an effort to be ecologically friendly.  However, judging by the state of the shed and the rest of the garden, I have my doubts.  So I am tagging this for Derelict Sunday hosted by Marlieske
