The scientific name for a carnation is Dianthus caryophyllus. The carnation comes in many colors including pink, red, white and yellow. You can recognize a carnation by the ruffle-shaped flowers. Carnations are often given to friends or loved ones on Valentine's Day, or to mothers on Mother's Day. If you receive a carnation, you may want to know how to preserve it as a keepsake.
Sprinkle some Borax over the flower part of your carnation. You want to get the Borax into the ruffles.
Spread a layer of borax at the bottom of the shoe box, and then lay your carnation on top of it.
Cover the rest of the carnation carefully with the borax. You want it to be completely covered so that no air gets to the flower.
Place the lid on the shoebox, and tape it shut.
Set the shoebox in a dry location for a week to 10 days.
Take the tape off the box after the designated amount of time has passed. Use a small brush to remove enough borax so that you can get to the carnation. Make sure you wear a pair of plastic gloves when you pick up the carnation and take it out of the box.
Dust the carnation off with a soft brush. You now have a preserved carnation. You can display it anywhere you like.
