I do weddings and many of the brides want their wedding party to have a nice remembrance of their wedding, so they select artificial flowers. Of course artificial flowers have no smell. I buy spray bottles of rose body spray and right before the ceremony, I spray all the flowers (including the pew bows) with a touch of the rose scent. The smell is so fresh and sweet, your family and friends would never know they were artificial flowers.
