Described herein is a module for covering a surface with vegetation. The module comprises a drainage board having an upper surface for supporting a growth medium. The drainage board has a plurality of moisture receptacles extending downwardly from the upper surface for collecting moisture. The module also comprises a plurality of sidewalls having a multiplicity of apertures therethrough. Each sidewall is coupled to the drainage board and extends upwardly therefrom. The sidewalls cooperate with each other so as to provide a perimeter for surrounding the growth medium. The module may also include other features. For example, the sidewalls may be pivotally coupled to the drainage board (e.g. along a living hinge), the module may include couplers for securing adjacent modules together, the sidewalls may include a reinforcing rib, the drainage board may include an opening for receiving an irrigation nozzle therein, and there may be edging for covering the sidewalls.
