I agree it's nice, but it wasn't my idea. There are a number of "green wall" vendors. I happened to see an installation in a nearby town and was really impressed. I had been thinking of building a trellis and that clinched it. Most installations are anchored to the building, but my design will be freestanding. I've got some 4x4s looking for a purpose.Wayneh, that's a fantastic idea for climbing plants. I used pieces of galvanized fencing but your proposed idea is much better and neater.
