PROBLEM TO BE SOLVED: To provide a method for enabling live flowers to be preservable for a long period and change in color with temperature/quantity of light. SOLUTION: A method for producing live flowers preservable for a long period and changing in color with temperature/quantity of light includes a dehydrating/bleaching process of precipitating live flowers in a solution obtained by mixing an alcohol, acetone and glycerine with distilled water, a preservation treating process of precipitating the live flowers passing the dehydrating/bleaching process in a solution obtained by mixing ethyl alcohol, methyl alcohol, isopropyl alcohol, acetone and an amino acid with distilled water, a first drying process of drying the preservation treated live flowers, and a process of adding colors to the live flowers passing the drying process.
