Patrick Blanc is a Parisian botanist and inventor of the Vertical Garden which relies on a new way to grow plants without any soil. Vertical gardens can be created on virtually any wall, indoors or outdoors. Watering and fertilization are automatic. Blanc’s gardens can now be found all over the world. A list of his projects (with photographs) can be found on his website, verticalgardenpatrickblanc.com/.
