A lawn edging consisting of an elongated extrusion made of a flexible and resilient polymer, the extrusion having opposite ends. The extrusion has a bottom, first and second side walls extending from the bottom and a transverse cross brace connecting the side walls together. The bottom has a toe portion extending perpendicularly from the first wall. The first wall is divided into an upper portion above the transverse cross brace and a lower portion between the transverse cross brace and the toe portion, the lower portion being perpendicular with respect to the toe portion. The upper portion of the first wall is at an obtuse angle to the lower portion such that the upper portion extends away from the lower portion of the side wall and away from the second side wall. The upper portion is configured to be flexible and resilient. The extrusion has an open top defined byte upper portion of the first and second walls which flare out relative to lower portions of the first and second walls.
