For the real planters, there are Crude Stone, Wood and Dark Brick Planters.
For the decorative ones, there are only the crude stone ones.
Also, the red lotus for example has no decorative Planter.
Would be nice to add all those, the graphics are all there.
OR You could get rid of decorative planters and enable the real ones to be picked up again. It works for the Radium Torches that have an inventory, why not for planters?
