PURPOSE: To provide a tiered flower contribution stand capable of efficiently supplying water to all of water tanks, preventing the contamination of water tanks and the leakage of water to the outside and reducing the sound of falling water during the supply of water.

CONSTITUTION: A flower contribution stand is constituted by arranging stepwise a plurality of water tanks A internally fitted with flower clampers holding flowers in an erected state. A weir plate 13 having damming-up height lower than the full water level of each of the water tanks is formed in each of the water tanks to form an overflow duct 14 and the lower end parts of the overflow ducts 14 of the respective water tanks A excepting the lowermost water tank are connected to the water tanks adjacent on the front lower stage side and a water supply part is connected to the uppermost water tank A-1 while the lower end part of the overflow duct 14 of the lowermost water tank A-5 is connected to a drain part. By supplying water to the uppermost water tank A-1, water can be successively supplied to the lowermost water tank through the overflow ducts 14 between the respective water tanks.
