Abstract: A border edging landscaping device having a below-ground vertical anchoring barrier to inhibit vegetation growth with an above ground border comprised of box-like structures formed along the upper edge of the barrier. The length of the barrier is formed by interconnecting identically formed components with each component having a first end that operates as a receptacle for receipt of a circular shaped flange located along a second end of a similarly shaped device. Receptacle formation allows for placement in a straight line configuration or perpendicular positioning to form borders for landscaping. The box-like structures may assimilate a brick and are formed in various colors providing an aesthetically pleasing border edging device. A beveled and serrated edge allows forceful insertion of the device.
