This is a collection of living walls (aka green walls, vertical gardens) from around the world. There is no titling or other identification, only images. You will see much of Patrick Blanc's creativity. If there is, in fact, an inventor of green walls he is the man.
Incidently, I believe that the terms green walls or living walls are more accurate descriptors than vertical gardens. Vertical garden is an imprecise term that can mean a number of things, including "skyscraper" farms and greenhouses on building rooftops among others. They are all in play at this time so take your pick.
