Abstract
A lawn edging device, for defining borders of lawns and gardens, that is adapted to hold plant seeds, so that when the plants mature their roots will extend through the device and help anchor the device in position in the ground. The device is an elongated article formed of a resilient, extruded, molded plastic material, and it includes a pair of thin vertical wall members that are joined at their lower ends to form a trough-like opening for holding seeds. At least one of the walls have openings at its lower end that allow roots of the plants to pass out of the device as the seeds germinate.
