I can't take credit for this, but it is one of the most original gardens I have seen. This afternoon it was install on the front wall of the library where I work.
The gardener has the plants in small pots, which he has in metal frame boxes. He attached tracks to the wall, and then slid the frames onto the tracks. He will water them daily, and can easily replace individual plants when he needs to.
