Gardening Up on the Roof

Gardening on roof tops may not be common place just yet, but it's getting more and more popular. It used to be people gardened on the roof because that was the only space they had. That's a good enough reason. But now they're finding that roof top gardens are energy savers and good for fighting pollution. Laura Porter, About's Guide to London for Visitors, has some examples of very creative roof top gardens designed for the Chelsea Flower Show. Take a look at her photo gallery, for a little inspiration. Just be careful up there! Photo Courtesy of Laura Porter
