Chrysanthemums (often called as mums or as chrysanths) are perennial flowering plants
of the genus Chrysanthemum, in the family Asteraceae, which are native to Asia and northeastern Europe. About 30 species have been described. Florists sometimes abbreviate the spelling to “xants”.

Yellow or white chrysanthemum flowers of the species C. morifolium are boiled to make a sweet drink in some parts of Asia. The resulting beverage is known simply as chrysanthemum tea. Rice wine flavored with chrysanthemum flowers is popular in Korea.

In Chinese cuisine steamed or boiled Chrysanthemum leaves are used as greens. The petals of chrysanthemum are mixed with a thick snake meat soup to enhance the aroma.

Small chrysanthemums are used in Japan as a sashimi garnish. Chrysanthemum plants have been shown to reduce indoor air pollution by the NASA Clean Air Study.
