PROBLEM TO BE SOLVED: To provide a cut flower exhibition device, capable of cleanly keeping water in a water vessel and extending the life of a cut flower so as not to reduce the quality of the cut flower. SOLUTION: This cut flower exhibition device constituted by arranging water vessels 1 in plural stages from a high place to a low place and supplying cool clean water as circulating to each of the water vessel 1, is provided by supplying water intermittently for overflowing water from each of the water vessels 1 for removing floating materials, installing a drainage port 14 connected with a drainage pipe pathway 8 at the bottom part of each of the water vessel 1 and electromagnetic valves V1, V2, V3 at the drainage ports 14, and operating the electromagnetic valves SV intermittently so as to discharge the precipitated materials in the water vessels. The electromagnetic valves SV are actuated alternately by a timer or a controller equipped with a clock circuit.
