Chrysanthemums are valuable ornamental flowers cultivated through long-term artificial selection. Around the eighth century, chrysanthemum as an ornamental was introduced from China to Japan. In the late 17th century, Dutch merchants introduced them into Europe, France in the 18th century and North America in the mid-19th century. Since then, Chrysanthemums have spread all over the world.

Chrysanthemums are plants with short sunshine, which can blossom early under short sunshine. They like sunshine but shade and are drought resistant but afraid of waterlogging. They like warm and humid climate, but they can also be cold resistant. Their roots can survive through winter underground and flowers can still bloom during slight frost. However, higher temperature is required for their seeds to grow and branch bud to bloom. The suitable temperature for them is about 20 ℃.

Chrysanthemums grow vigorously and have strong sprouting power. A chrysanthemum can produce thousands of flower buds after picking for many times. Some varieties of branches are soft and many, which are convenient for making them into various shapes, such as chrysanthemum tower, chrysanthemum bridge, chrysanthemum fence, chrysanthemum Pavilion, chrysanthemum door, chrysanthemum ball and so on, adding countless ornamental works of art to the annual Chrysanthemum Exhibition.

There are many kinds of chrysanthemums, and different colors have different symbolic meanings. In China, white chrysanthemums symbolize sadness and mourning. They are usually used in funerals to express condolences, respect, and remembrance for dead relatives. In Japan, white chrysanthemums represent chastity and honesty.

Yellow chrysanthemums are common in life. They symbolize prosperity. When the yellow chrysanthemums bloom, they are like gold on the ground, which is very dazzling. Yellow chrysanthemums can be given to friends or leaders to wish them a great future and a prosper career. In addition, yellow chrysanthemums can also be given to teachers and elders, which means respect and nobility.
