A powered edging assembly for providing a voltage source at an edge of a garden or lawn having an edging extrusion configured for in-ground placement at the edge and including an above-ground upper portion having contained wires extending along a length of the extrusion; the wires being insulated by penetrable sheaths. An electrically powered device is selectively positionable and fastenable on the extrusion, whereby contacts for the device penetrate the sheaths for communicating electrical power from the wires to the device.
