A vegetation support system (10) comprises a support frame (11) for mounting to wall (12). The support frame (11) includes upright beams (14) having an inner end (16) and an outer end (18). Growth medium containers (20), having a cavity (26) for receiving a growth medium (28) and an outer panel (24), are mounted to the upright beams (14) such that the cavity (26) is arranged inwardly of the outer end (18) of the upright beams (14) and the outer panel (24) is adjacent to the outer end (18) of the upright beams (14). Apertures (34) are formed in the outer panel (24) of the growth medium container (20) allowing vegetation to be planted through the apertures (34) into the growth medium (28).
