Chrysanthemums, often called mums or chrysanths, are perennial flowering plants of the genus Chrysanthemum in the family Asteraceae which are native to Asia and north-eastern Europe. Chrysanthemum species are herbaceous perennial plants growing to 50–150 cm tall, with deeply lobed leaves with large flower heads that are generally white, yellow or pink in the wild. They are the preferred diet of larvae of certain lepidopterans.
Chrysanthemums were first cultivated in China as a flowering herb as far back as the 15th century BC. The flowers occur in various forms, and can be daisy-like, decorative, pompons or buttons. The "Festival of Happiness" in Japan celebrates the flower.
