The carnation, in general, is a symbolic flower that has to do with the bonds of affection. It is a symbol, also, of health and energy, along with fascination and love.
The name "carnation" comes from "coronation" or "corone," meaning flower garlands. This is because carnations were often used in Greek ceremonial crowns. Some scholars disagree with this and say that the name comes from the Latin word 'carnis' meaning 'flesh' because of its pink colour.
Every flower has a specific message. The carnations floral message dates back to ancient Rome. At that time, the carnation was known as "Jove's Flower." The Romans used this flower in their tribute to a beloved god.
In Korea, the carnation takes on very serious symbolism. There, a young girl may put three carnations in her hair to tell her fortune. If the top flower dies first, the girl knows that her last years of life will be difficult. If the middle flower dies first, her youth will be difficult. But, if the bottom flower should die first, the girl is told that her whole life will be miserable.
