Transform what would otherwise be a dull, utilitarian area into a bright, creative feature by planting up your water butt lid with drought-tolerant plants. Sedums, crassulas, sempervivums and other succulent hardy species are perfectly adapted to growing in very shallow soils, because their fleshy leaves are excellent at storing water, allowing them to hunker down during prolonged periods of drought. Once planted up, this living roof requires very little maintenance. A water butt lid offers only 2cm depth of soil, but these robust plants will happily grow here, evolving into a rich, interwoven tapestry of colours.
