Abstract: A landscaping timber system includes a molded plastic landscaping timber having ends configured to link with ends of other such timbers via elongate spikes inserted through aligned apertures in the ends of the timbers and driven into the ground. The timber includes an integral storage compartment for storing a spike therein during storage or shipping of the timber. The timber can also include one or more weep vents in the bottom surface of the timber to allow water to flow under the timber. The system also includes a flush-mount adapter for attachment to a stepped end of a timber to give an appearance of a non-stepped end so that the timber can be mounted flush against a wall. The system further includes a ramp assembly for providing access to an area bounded by the timbers, and an end adapter enabling a timber to be cut to a desired length and attached to the adapter so as to provide a custom-length timber.
