A retaining wall has precast concrete wall facing elements and is constructed to accommodate vegetation masking. The structure uses panels having frontally projecting buttresses and inwardly inclined face surfaces to provide an exposed horizontal planting bed for each row of panels. Devices are provided to limit water percolation and migration of fine particles. And, rearwardly projecting bearing pads may be added to give columnar support in high wall application.
