Chrysanthemums,
sometimes called mums or chrysanths, are flowering plants of
the genus Chrysanthemum
in the family Asteraceae. They are native to Asia and northeastern Europe. Most
species originate from East Asia and the center of diversity is in China. There are about 40 valid species. There are
countless horticultural varieties and cultivars. The genus once included more
species, but was split several decades ago into several genera, putting the
economically important florist's chrysanthemum in the genus Dendranthema. The naming of the
genera has been contentious, but a ruling of the International Code of
Botanical Nomenclature in 1999 changed the defining species of the genus to Chrysanthemum indicum, restoring the
florist's chrysanthemum to the genus Chrysanthemum. Source
