An agriculture professor in Texas recommends about two ounces of Listerine mouthwash per gallon of vase water to extend the life of cut roses and other cut flowers. Listerine contains, among other things, sucrose (food for flowers) and a bactericide. Its acidity promotes quicker uptake of water by the stems.

Reply:silica-gel crystals! when the rose is open to the point you want to keep it, put it in silica-gel crystals (available at any craft store and some hobby shops). follow directions on container (basically, pour some crystals in container, add rose, and slowly add crystals to gently cover rose, shaking gently to get the crystals inside the petals, and cover about i/2 to 1" over rose. put lid on container and wait about a week.) pour of crystals and take a small artist paintbrush and very gently brush off crystals and dust. spray with a clear acrylic sealer or paint and you will have your "fresh" rose forever, and it will look very alive and real...its really cool...it will look like you just picked it...forever....
