In Japan, there's even a "Festival of Happiness" to celebrate this flower each year. A symbol of the sun, the Japanese consider the orderly unfolding of the chrysanthemum's petals to represent perfection, and Confucius once suggested they be used as an object of meditation. It's said that a single petal of this celebrated flower placed at the bottom of a wine glass will encourage a long and healthy life.
