Abstract: A flowerbox support bracketing comprising a plurality of similar L-shaped members and a generally Z-shaped member. The L-shaped members each have a first arm and a second arm, each arm formed with elongated longitudinal slots. The generally Z-shaped member comprises a vertical arm and horizontal top and bottom arms, the horizontal arms being directed in opposite directions and the top arm defining an aperture to receive a bolt wherein a wing nut is threadedly engaged. By overlapping the first and second arms of the L-shaped member with the top arm of the Z-shaped member a flowerbox is clamped to a wall or the like by the descending of one L-shaped arm into the flowerbox's interior and the other L-shaped arm descending over the back of the wall for engagement thereto.
