Abstract: A landscape-edging device is disclosed which may be used to segregate dissimilar landscaping schemes by positioning the device into the soil. The landscape edging is made of flexible strips, designed for continuous end-to-end attachment. The edging is attached to the soil by stakes. The edging system is designed so that stakes are removably attached to the device. The individual sections are joined together by a connector that is nested within open channels on one face of the lawn edging device and secured in place to the adjacent lawn edging sections by one or more buttons that releasably seat within holes in the lawn edging section. Each section can be cut to size, if needed, to tailor the joined sections to a particular landscape scheme. The lawn edging device is generally symmetric in cross section about a horizontal equator of the device.  The lawn edging device is easily adapted and configured to a particular landscape scheme because it is severable to meet size requirements. Moreover, the connection system is easily and securely applied to the adjacent sections and the sections are symmetric allowing for easy orientation and installation.
