To provide a special processing method for a preserved flower enabling inexpensive light-accumulation processing of a preserved flower and also long retention of the aroma of the flower for a half through one year or more, and simultaneously performing both of light accumulation and aroma retention, through eliminating defects in expensiveness and lack of long-term retention of aroma in a conventional method of spreading light accumulation spray or applying an aromatic agent well known as a method of light accumulation and aroma processing for the preserved flower.

The special processing method for a preserved flower comprises dissolving or dispersing a light accumulation material or an aromatic agent into relatively inexpensive and highly permeable alcohol comprising at least one kind of methanol, ethanol, butanol, isopropanol, cellosolve and the like, and soaking the preserved flower in the alcohol so as to perform light accumulation processing or aroma retention processing. In the method, two of materials comprising the light accumulation material and the aromatic agent may be dissolved or dispersed in the alcohol at the same time so as to soak the preserved flower in the alcohol mixture.
