A framing unit used with a plurality of replaceable panels that form a vertical retaining wall or a rigid enclosure used to make raised planting beds. The framing unit includes two vertical end connectors, two horizontal top rails, at least one bottom rail, and a plurality of vertical panels. Each end connector includes two side flanges joined to form a vertical channel Formed on the outside surface of each connector is at least one hinge sleeve offset from the hinge sleeve on the opposite end connector. The sleeves on opposite end connectors are offset enabling adjacent framing units to be joined with a single anchor pin. The bottom and the two top rails are parallel and extend between the two end connectors. The top rails are separated by an upper gap that allow a plurality of vertical panels to be inserted into and supported by a channel formed on the bottom rail. The top edges of the panels are captured by the two top rails.
