The giving of flowers drifts back into the haze of centuries gone by. There's very few of us that haven't at some point given flowers as a gift to someone. Archaeologists have found traces of flower petals in prehistoric graves. There are records of flowers been given in Egyptian hieroglyphics. Have you heard of the Language of Flowers? This was a Persian tradition of using flowers as a message , which the enemy would not perceive or understand. The Victorians took this on & developed floriography, continuing to use flowers as messengers, but more to discreetly express feelings. The red rose implied passionate romantic love. So this Valentine's Day you can really say it with flowers!
