Chrysanthemum
Chrysanthemums (/krɪˈsænθəməmz/ kriss-AN-thə-məmz), sometimes abbreviated to 'mums' or 'chrysanths', are perennial herbaceous flowering plants in the family Asteraceae that bloom in the autumn. They are native to East Asia and northeastern Europe. Most species originate from East Asia, and the center of diversity is in China. Many thousands of horticultural varieties and cultivars exist.
The genus Chrysanthemum consists of perennial herbaceous flowering plants, sometimes subshrubs. The leaves are alternate, divided into leaflets and may be pinnatisect, lobed, or serrate (toothed) but rarely entire; they are connected to stalks with hairy bases.
The compound inflorescence is an array of several flower heads, or sometimes a solitary head. The head has a base covered in layers of phyllaries. The simple row of ray florets is white, yellow, or red. The disc florets are yellow. Pollen grains are approximately 34 microns.[citation needed]
The fruit is a ribbed achene.
The name "chrysanthemum" is derived from the Ancient Greek: χρυσός chrysos (gold) and ἄνθεμον anthemon (flower).
The genus Chrysanthemum was first formally described by Linnaeus in 1753, with 14 species, and hence bears his name (L.) as the botanical authority. The genus once included more species, but was split several decades ago[when?] into several genera, putting the economically important florist's chrysanthemums in the genus Dendranthema. The naming of these genera has been contentious, but a ruling of the International Botanical Congress in 1999 changed the defining species of the genus to Chrysanthemum indicum, restoring the florist's chrysanthemums to the genus Chrysanthemum.[citation needed]
Genera now separated from Chrysanthemum include Argyranthemum, Glebionis, Leucanthemopsis, Leucanthemum, Rhodanthemum, and Tanacetum.
As of September 2025[update], Plants of the World Online accepted the following species:
