The effect of Aspirin® and Aspirin® Plus C and their active ingredients acetyl salicylic acid and ascorbic acid as household remedies for prolonging cut flower life was analysed in comparison to a commercial cut flower food (Chrysal) and a untreated control in several experiments with six cut rose cultivars in a growth chamber. Therefore practical consumer units (one or two tablets) were observed. All Aspirin® and active agents treatments reduced the shelf life of the roses highly significant. Generally increasing concentration led to a decreased flower longevity. Aspirin® and active agent treated roses showed already at the second day of the tests a lot of dried and later necrotic leaves what reduced their optical value and led to an early end of vase life after 4.5 days in average. Furthermore the rose flower buds demonstrated almost no development with these treatments. In contrast the use of the cut flower food resulted in a highly significant longer shelf life (9.6 days) compared to untreated tap water (7.4 days). So instead the use of pharmaceutical Aspirin® products as a household remedy for extending vase life of cut roses, the use of an effective cut flower food or only water is recommended.
