Abstract
A plantable retaining wall block having a plant-receiving cavity located in a top surface thereof. The block is constructed so that the plant-receiving cavity lies between portions of side walls which are generally parallel with a front face of the block. The shape of the block is such that a nearly vertical retaining wall may be constructed such that each plant-receiving cavity is substantially exposed to allow vegetation to be planted. The wall block may include a connection member or an alignment member to allow the block to be stabilized and aligned with blocks in adjacent rows of a retaining wall.
