Lawn edging system and associated edging components

A lawn edging component for being releasably joined with other said edging components to produce a barrier of a sufficient height above a surface of the ground to be suitable for holding within a perimeter formed by said component together with other of said components a quantity of mulching materials, for blocking the lateral growth of adjacent grass, weeds, and such like flora, and for being supported on the surface of the ground, said edging component comprising a body having first and second end portions, said second end portion of said body defining an indented section provided in said upper surface of said body for releasably receiving said first end portion of another said component, whereby said edging component and another said edging component are releasably joined, said body including:

• an upright portion having a cross-section substantially defining an inverted U-shaped configuration, said upright portion extending substantially the length of said component, said upright portion defining first and second oppositely disposed sidewalls for forming a barrier to the passage of materials placed thereagainst and the lateral growth of weeds and grass, each said sidewall defining a lower portion;
• a first flange carried by and extending outward from said lower portion of said first sidewall of said upright member, and extending substantially the length of said component, said first flange defining a lower planar surface for flush engagement with said ground surface for substantially preventing the lateral growth of grass and weeds;
• and
• a second flange carried by and extending outward from said lower portion of said second sidewall of said upright member and extending substantially the length of said component, said second flange defining a lower planar surface for flush engagement with said ground surface for substantially preventing the lateral growth of grass and weeds.
