Flowers

Scientists say there are over 270,000 species of flowers that have been documented and are living in the 21st Century. But scientists have yet to answer basic questions about these marvels of beauty... What led to their amazing diversity? Are there flowers that have not changed much during the evolution of this planet?
The first plant fossils found were woody magnolia-like plants dating back 93 million years. Paleobotanists have more recently uncovered tiny herb-like flower fossils dating back 120 million years. Flowering plants, called angiosperms by scientists, were believed to be already diverse and found in most locations by the middle of the Cretaceous period… 146 million years ago.
A myriad of images of preserved flowers and flower parts [in very fine detail] have been found in fossils located in Sweden, Portugal, England, and along the Eastern and Gulf coasts of the United States.

The language of flowers, sometimes called floriography, was a Victorian-era means of communication in which various flowers and floral arrangements were used to send coded messages, allowing individuals to express feelings which otherwise could not be spoken. This language was most commonly communicated through Tussie-Mussies, an art which has a following today.
The nuances of the language are now mostly forgotten, but red roses still imply passionate, romantic love and pink roses a lesser affection; white roses suggest virtue and chastity and yellow roses still stand for friendship or devotion. Also commonly known meanings are sunflowers, which can indicate either haughtiness or respect – they were the favorite flower of St. Julie Billiart for this reason. Gerbera (daisy) means 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 signifies thought, a daffodil regard, and a strand of ivy fidelity.
