In this, various flowers and floral arrangements were used to send coded messages, allowing individuals to express feelings which otherwise could not be spoken. The language was most commonly communicated through Tussie-Mussies, an art which has a following to this day.
Also some of the other commonly known meanings for flowers are sunflowers, which can indicate either haughtiness or respect and Gerbera (Daisy) can mean innocence or purity. The iris, being named for the messenger of the gods in Greek mythology, still represents the sending of a message. A pansy can signify thought, daffodil signifies regard, and a strand of ivy signifies fidelity.
Now, do keep in mind that Florigraphy is a special interpretation of what messages a particular flower should communicate. These do not necessarily have a direct co-relation with how flowers can be used to communicate natural-energy messages. Flower Divination is an entirely different approach to understanding and interpreting Nature-Wisdom (i.e. messages from the natural world).
How flowers are used in oracle wisdom... their divination-interpretation is completely different from Victorian Florigraphy and is something that has been practiced by many ancient cultures since time immemorial!!
