I really like the idea of a vertical herb garden for people like me who are a little space challenged. Our home has a nice sunny courtyard that could really do with some greenery. I have found a local company called Lushe who are vertical garden enthusiasts and sell systems for us mere mortals to try and emulate the great work of Patrik Blanc. They also document different types of vertical gardens they have come across like the
the edible wall in an LA Pizza restaurant.
Maze vertical garden which I think look great and no surprise that it comes from uber-cool US retailer CB2.
