     Chrysanthemums (菊花) are to the fall what tulips are to the spring.

     In ancient China, chrysanthemums (or 'mums' for short) were first planted thousands of

years ago. People chose the chrysanthemum as their Flower for October, a symbol of the rest and ease

that followed the season's final harvest. Then they symbolized a scholar in retirement (隐居) and were

one of the four noble plants, along with bamboo, the plum flower, and orchid.

     The Japanese hold the chrysanthemum as a symbol of the sun. They consider the orderly unfolding of

its petals to be a symbol of perfection. They also think that a single chrysanthemum petal placed in the

bottom of a wine glass encourages a long and healthy life. The Japanese even have a National

Chrysanthemum Day on September 9, known as the Festival of Happiness.

      In the United States during colonial times, its popularity grew such that mums now reign as "Queen of

the Fall Flowers." Mums remain the most widely grown pot plant in the country and the largest

commercially produced flowers. Chrysanthemums generally represent cheerfulness and rest. So they are

welcomed throughout the British Isles and North America for any occasion, such as football games and

parties. In other countries such as Italy, Belgium and Austria, however, their association with the dead

makes chrysanthemums acceptable only for funerals and graves.
