Martha Stewart did a special on living walls as you can see below:

It looks like the wall panels from ELT Living walls were used to hold the plants. Those panels are about 20″ x 20″ x 2.5″ deep. The panels are at a 45 degree angle and the plants are planted right in the 2.5″ of soil. In this case, Kirei Board was used to make a really good-looking frame around it. You can really see that by really stuffing the wall with plants, you get a solid green wall. It looks amazing.
