A landscaping block (1) for a retaining wall includes a bottom wall (2), a pair of wide sidewalls (3, 5), first (7) and second end walls, and upper (13, 15, 11, 19) and lower steps on the sidewalk for interlocking with overlying and underlying blocks. The blocks also include a transversely extending step (14, 16) that extends downwardly from one end of the bottom wall (2) for engag- ing an underlying block while preventing a front (24) wall of an overlying block from contacting the front wall of the underlying block.
