A friend of mine ask me to make the stucture for this neat container garden that portrays a balanced tower of flowers. Everything about this metal project is hidden, but it works. I used a four-foot piece of 1/2 inch round bar welded to a metal base. The base is the same diameter as the bottom pot, so it is not visible. I added a couple of stabilizer fins also. The pots are installed by sliding them over the rod. The drainage hole in each pot keeps them centered nicely. The last step is to add soil and plants.
