During the victorian period it was very common to send messages with floweres, a custom that is no longer followed but some meanings remaning, for example the color of the flowers.

Why not say what you feel with flowers?

Red: Love

Pink: Grace

White: Innocence, purity, humility

Yellow: Friendship, dying love, agonizing love, platonic love. In some countries it means jealousy or infidelity.

Lavender: Love at first sight.
