  • Publication number: 20170034999
    Abstract: A landscape edging piece which forms a boundary between a landscaped bed and a mowed lawn area. The edging piece has a top face that is inclined downwardly from the endwall that abuts the landscaped bed, so that the endwall that abuts the mowed area is at approximately lawn level. The edging piece is formed by molding and has integrally formed anchoring spikes that secure the piece in the desired location. The edging piece used in a landscaped area appears the same as a conventional paver, but is far less expensive to install since it does not require digging to place it in the proper position.
