Plastic extruded lawn edging includes a vertical panel and a horizontal panel that are reconfigurable to a storage position and an installed position. In the storage position, the lawn edging has a relatively low minimum moment of inertia for the flexibility of coiling about itself. In the installed position, the lawn edging has a higher minimum moment of inertia for greater rigidity when in use. The horizontal panel is wide enough to support the wheel of a lawnmower and provides a band along which no grass can grow. The horizontal panel eliminates the need for grass trimming wherever it is used, such as along side the outer wall of a house or around a garden.
