This stacked flower tower is easy to make and it can become an eye-catching outdoor piece. The complete supply list for this project includes 3 plastic pots, a garden flag stake, some potting mix and flowers. Cut the decorative curve off the top of the flag stake so you have a straight post, which can be embedded in the ground, which helps keep the flower tower upright. Drill holes in the bottom of the pots just slightly larger than the diameter of the garden stake. Slide the pots over the post at alternating angles until you come up with a look that you like. Add the soil and the plants and voila!
