I am sorry to learn that your original bouquet and the first replacement did not last as long as expected. Generally the vase life of Daffodil flowers varies slightly. It varies from 6-8 days under standard conditions at 15.5 degrees c, but this will change if the environment is warmer or cooler. Daffodil flowers are sensitive to ethylene, which shortens their vase life. I am glad to hear that the second repalcement lasted longer than thepervious two items, and we apologise for any inconvnenience caused.
