Birthdays are actually a pagan tradition that began with the ancient Greeks. They thought that each person was given a spirit that watched over them from the day of their birth. Birthdays were a way of celebrating this spirit.
As with many Greek traditions, the Romans continued it after they came to world dominance. Eventually, birthday celebrations became part of the Christian tradition and subsequently moved all over the globe.
But, what does all of this information have to do with birthday flowers?
Giving the gift of flowers is just one way to celebrate a birthday. Gifts have been part of the birthday celebration forever. The gifts were originally offered to the person’s protective spirit in the Greek tradition. Today, gifts are given to the birthday person as a way of celebrating them.
