These red Kamelia Wall Planters are suitable for either indoor or outdoor use and can be easily clipped together for a vertical wall/balcony display or simply left individually on a flat surface to serve as standalone pots. Included with each planter is a reservoir cover to prevent unwanted overflow. For vertical displays we recommend removing the cover from higher planters to allow excess water to irrigate lower planters on the chain. For indoor use simply make sure the bottom planter has its reservoir cover in place to prevent any further overflow (the same obviously applies to standalone pots). UV protected, each planter is made from the highest quality plastic and has been designed to withstand the extremes of the Australian climate.
