At some point in our lives, we would experience the joy appreciating the beauty of flowers, the happiness in giving flowers or and the excitement of receiving them. A flower itself does not have any meaning, just like a cat or a fish. But it's the human emotion that gives a certain value to it and our interpretation gives it a consistent meaning over time. For example, you will see a man giving a bunch of red roses to express his admiration and love to a woman. But you will hardly see anyone with the same bunch of red roses at a funeral. The meanings of the same flower would evoke different emotions with different implications on a different context.
