12. The tray of claim 8 , further comprising a means for securing the drain hole cover over the drain hole.

13. The tray of claim 12 , wherein the means for securing is an adhesive.

14. The tray of claim 5 , wherein at least one of the plurality of vertical side panels includes a connecting hole.

15. The tray of claim 5 , further comprising an absorbent medium and vegetation disposed on the bottom panel.

16. The tray of claim 15 , wherein the absorbent medium includes a soil mixture and an absorbent material.

17. The tray of claim 5 , wherein the tray is approximately square.

18. The tray of claim 5 , wherein the two vertical side panels including the U-shaped upper edges are adjacent to each other.

19. The tray of claim 18 , further comprising a notch disposed in the corner between the two vertical side panels including the U-shaped upper edges.

20. A vegetation roofing system, comprising:

a first tray; and

a second tray adjacent to the first tray;

each of the first tray and the second tray including:

a bottom panel;

a plurality of vertical side panels; and

wherein the plurality of vertical side panels are integrally formed with the bottom panel; and

at least one drain hole disposed in the bottom panel to release liquid from each of the first tray and the second tray;

wherein an interconnecting lip couples adjacent vertical side panels of the first and second trays, the interconnecting lip being formed by a U-shaped upper edge integrally formed along an entire length of one of the adjacent vertical side panels between corners thereof and overlapping a straight upper edge of the other of the adjacent vertical side panels so as to cover a gap between the first tray the second tray.

21. The system of claim 20 , wherein the U-shaped upper edge of a substantially entire length of one of the vertical side panels of the first tray overhangs the straight upper edge of one of the vertical side panels of the second tray such that the interconnecting lip extends inside the second tray.

22. The system of claim 20 , further comprising a securing device penetrating adjacent connecting holes of the first and second trays.

23. The tray of claim 22 , wherein the securing device is a quick-lock fastener.

24. The system of claim 20 , wherein each of the first tray and the second tray further includes a protruded portion, the system further comprising a clip engaging the protruded portions on the first and second trays.

25. The system of claim 24 , wherein the protruded portions are disposed on the vertical side panels of the first and second trays and protrude toward an interior of the first and second trays from the vertical side panels.

26. The system of claim 20 , further comprising a wall anchor flashing overhanging one of the vertical side panels of the first tray.

27. The system of claim 26 , further comprising a fastener securing the wall anchor flashing to a wall.

28. The system of claim 26 , wherein the wall anchor flashing comprises a connecting hole and a securing device penetrates a connecting hole of the first tray and the connecting hole of the wall anchor flashing, thereby securing the first tray to the wall anchor flashing.

29. A vegetation roofing tray, comprising:
