I've been skeptical of vertical gardens for vegetables, so it's only fair to recognize they seemingly can work for ornament. Treehugger has a 4-year later followup on a vertical wall in Madrid. Being cynical I wanted to check when the photos were taken because it wasn't clear. But I finally did see a photo of the garden as originally installed, and it's definitely different than the one in the treehugger post. They do mention an irrigation system, but apparently it's fairly carefree.
