Abstract
A landscape edging or border block has an essentially trapezoidal shape, and is capable of being used to form a linear, serpentine or combination border or edge. The blocks can also be used to enclose an area. By orienting each block such that its inner edge faces inwardly, a substantially circular shape is attained to enclose a circular area. To expand the area to be enclosed, at least two expansion blocks are added for each quadrant of the shape. The two expansion blocks are oriented so as to provide a linear segment in each quadrant between adjacent ends of each arcuate segment. Additional pairs of expansion blocks can be added for each quadrant to further expand the area to be enclosed. In all cases, the enclosed area is formed by placing adjacent blocks such that their edges engage each other to form a shape without the presence of gaps between adjacent blocks.
