This is a great planter and can be used indoor or outdoor.  However you will need to position your plants accordingly.  I would suggest placing a small sago palm in the middle basket that is lowest because there is not a lot of room for a plant with flowers or hanging leaves/vines.  One you decide the spacing, I would suggest filling the baskets with different plants.  One flowering, one small sago palm, one tall colorful plant such as a sage, and finally one green plant that has broad leaves to add some depth.
