Chrysanthemums are native to Asia and northeastern Europe. Most species originate from East Asia and the center of diversity is in China.
Chrysanthemums were first cultivated in China as a flowering herb as far back as the 15th century BC.
Modern cultivated chrysanthemums are showier than their wild relatives. The flower heads occur in various forms, and can be daisy-like or decorative, like pompons or buttons. From Wikipedia
