ABSTRACT:
A planting box having a frame which consists of a plurality of vertical walls and being of polygonal cross-section is provided with vertical channels and vertical ribs. The channels and ribs are complementary in their cross-section. Ribs of one planting box fit into the recesses of another identical planting box, so that a planting arrangement can be erected which consists of a plurality of inter-connected identical boxes. In each channel of the planting boxes supporting shoulders are formed which support the ribs of a laterally adjacent planting box, so that each box is vertically offset with respect to any laterally adjacent box by half of the box height.
