The yellow chrysanthemum is associated with November.
Chrysanthemum is derived from the Greek words chrysos, meaning gold and anthemon meaning flower.
Cultivated over 3,000 years ago in China, the Chrysanthemum is known as the “Flower of the East” and the “Flower of Life”. Tao Yanming was the first historical breeder (around in 400 A.D). After his death, his hometown was named Juxian meaning “City of Chrysanthemums”.
According to Chinese Feng Shui chrysanthemums bring happiness into your home.
“The Japanese tell the legend of twelve young maidens and twelve young men who set out from China to find the “herb of youth,” which they believed kept people eternally young. In order to trade for this herb, they carried with them baskets of chrysanthemums. When their ship wrecked near an uninhabited island, they swam ashore and planted the chrysanthemums. It was the first introduction of chrysanthemums to Japan, and to this day the imperial coat of arms of Japan shows a golden chrysanthemum with sixteen petals.”   http://www.nhs.usethis.com/
