Abstract
A method of preserving cut flowers such as roses, tulips, carnations and mums, by the insertion of the freshly cut stems of cut flowers in a solution of a water-soluble polyamino organic acid, preferably polyaspartic acid. The life of a flower, as it appears healthy and viable without stem bending or senescence of the flower itself, is substantially prolonged, in many cases two to three times longer than untreated flowers.
