Flowers were chosen as symbols for many reasons. The great variety of flora made it possible to find some plant or flower which would be a suitable figure for nearly any abstract quality or condition. A plant might be chosen because of some myth connected with its origin, as the stories of Daphne and Narcissus; because of the peculiar environment in which it thrived, as the orchid and the fungus; because of its significant shape, as the passion flower and the Easter lily; because of its brilliance or fragrance, as the verbena and the sweet lavender; because it preserved its form indefinitely, as the everlasting flower; because of unusual characteristics as the sunflower and heliotrope, which have long been sacred because of their affinity for the sun.
