DO NOT PUT THEM IN PLASTIC. We don't need your roses fresh, however, we can't use roses that have molded. So, once you bring them home, if they have been removed from the stems by your funeral director, keep them in a paper bag in a cool place until you can make arrangements to ship them or make an appt. to deliver them to our workshop. We don't advise keeping them in your refrigerator for more than 2 weeks. If they are still in the original arrangement, you may enjoy them as long as you like. All that will happen is they will begin to droop and wilt, which is fine. Once they get to that point, you may ship them or make an appt. to deliver them to us.
