Abstract
Abstract The present invention relates to an improved extruded plastic elongated edging strip for use in gardening. The instant edging strip is particularly adapted for being positioned in the ground to separate growing areas in order to keep one type of plant on one side of the strip and thereby prevent an undesired comingling of plants. The subject edging strip includes a flexible thin upright wall which has a bead on one longitudinal edge. The bead is formed integral with the upper or exposed edge of the edging strip. The upright wall has a plurality of ears hingedly formed in the wall. The ears are adapted to extend away from the thin wall for engagement with the earth to hold the edging strip in place.

Claim 1
Independent Claim
174 words
An elongated extruded plastic garden edging strip adapted for being positioned in the ground to separate plant growing areas comprising: an elongated flexible thin upright wall, said upright wall having an elongated bead formed integral with one edge of the wall, said wall having a lower edge opposite to the one edge, and an ear having one edge formed integral with the wall and being hingedly connected to said wall by that one edge and having a free edge, said free edge being adjacent to the one edge of the wall having the bead, said ear being formed of a portion of the wall to form an opening in the wall when the free edge of the ear is pivoted outward away from the wall about the edge of the ear formed integral with the wall, the thin wall includes a plurality of elongated ribs formed integral with the thin wall and extending outward from the thin wall, said ear having a portion of one of said ribs on one surface of the ear.
