What is the ideal refrigeration temperature for normal flowers?

The ideal refrigeration temperature for most cut flowers is between 38 and 40 degrees Fahrenheit. This temperature range is crucial because it helps to slow down the respiration rate of the flowers, which in turn prolongs their freshness and shelf life. At this cooler temperature, cellular processes are reduced, helping to prevent wilting and decay, while also minimizing the growth of bacteria or mold that can negatively affect the flowers' quality.

Storing flowers at temperatures significantly higher than this range (such as in options mentioning 50-55 degrees or higher) can lead to faster deterioration due to increased respiration and transpiration rates. Conversely, temperatures that are too low, while not stated in this question, can cause chilling damage to certain types of flowers if they are not acclimated properly, but the recommended range is ideal for most varieties. Thus, maintaining a refrigeration temperature between 38 and 40 degrees is essential for preserving the beauty and longevity of cut flowers.
