It is an enchanting idea to me that flowers express themselves so clearly that they have become recognised symbols of their own energy. They are, to me, a hopeful representation of the notion that if we could be truly ourselves, without the shroud of our doubts and fears and unobscured by our 'shoulds', that self expression would be effortless and that we would be completely understood.
There is a language, little known, Lovers claim it as their own. Its symbols smile upon the land, Wrought by nature's wondrous hand; And in their silent beauty speak, Of life and joy, to those who seek For Love Divine and sunny hours In the language of the flowers. –The Language of Flowers, London, 1875
We have been attributing meaning to flowers for so very many years that the 'language of flowers' now even has its own name - floriography. Victorians sent coded messages using flower arrangements. For example;
roses symbolise love
daffodils symbolise chivalry
lilies symbolise beauty
daisies symbolise purity and innocence
gerberas symbolise cheerfulness
The colour of the flower conveys meaning too.
red - passion and love
orange - expansion, growth, and warmth
yellow - clarity, truth and intellect
green - renewal, growth, hope, health and youth
blue - dreams, inspiration, tranquility
indigo - emotions, depth, intuition and expressive moods
violet - royalty, nobility and spirituality
