Got this off of ebay and trying to figure out what to plant in it....it is aluminum-- 7-1/2 inches across & 4 inches deep. I'm planning to line it with garden fabric if needed to hold the soil etc in. My thought right now is to put a Tolumnia orchid in it since they stay small and have such pretty blooms. Would there be any problems with the metal bothering the plant?
Open to other ideas also!
