This seems to have evolved in us in response to one of the evolved functions of flowers which is to provide information about the plant. Our appreciation of the beauty of flowers may well be innate or instinctive and be an adaptive response to colourful cues in the environment which originally helped primitive hominid species to find sources of food. With experience flowers tell us a lot about the ripeness of a plant's fruit. Plants use flowers, the reproductive part of the plant, to attract animals and insects to assist in their reproduction through pollination and the spread of seeds.
