The iris symbolizes good news and luck. It is also said the its three upright petals symbolize faith, valor, and wisdom.
The iris got its name from the Greek goddess of the rainbow, Iris. She was the messenger of the gods, and would ride on the rainbow to and from Earth in her beautiful, multicolored robes. She acted as the link between heaven and earth. It is told that irises were planted at the graves of women. People believed that this would summon the goddess to guide the souls in their journey to heaven.
During the Middle Ages, irises became linked to the French monarchy. Eventually, this flower became the French national symbol, the fleur-de-lis.
The iris is also recognized as the February birth flower, the 25th wedding anniversary flower, and the state flower of Tennessee.
