Flowers are used to express feelings and emotions to one another. Flowers are also used to mark occasions. Our lives are touched with flowers.
Different flowers have different meanings, and the meanings behind them can be just as touching. Beyond love, they symbolize many other things, such as reconciliation (hazel), overcoming obstacles (mistletoe), hope (iris). The meanings also differ from culture to culture, which is why a flower can have more than one meaning.
The symbolism of flowers is seen in stories, in artwork, in poems, going back through time. Shakespeare himself included symbolism in Hamlet, in the scene where Ophelia gives out flowers during her madness.
