Rose in refrigerator

General

Florists keep their roses (and just about everything else) in the refrigerator. My cut roses seem to keep a little while in my refrigerator as well.

If refrigerated overnight, they also seem to last a while longer once taken out and put in the vase.

Is that my imagination?

I meant they seem to last a little longer than the roses that have been cut and immediately put in the vase.
