Chrysanthemums, sometimes called mums or chrysanths, are flowering vegetation 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 many horticultural varieties and cultivars. The name "chrysanthemum" comes from the Ancient Ancient greek:?????? chrysos (gold) and Ancient Greek:??????? anthemon (flower).
Taxonomy
The genus once included more species, unfortunately he split several decades ago into several genera, putting the economically important florist's chrysanthemums in the genus Dendranthema. The naming of the 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.The other species recently contained in the narrow view of the genus Chrysanthemum are now used in the genus Glebionis. The other overal separate from Chrysanthemum include Argyranthemum, Leucanthemopsis, Leucanthemum, Rhodanthemum, and Tanacetum.
Description
Outdoors Chrysanthemum taxa are herbaceous perennial plants or subshrubs. They have alternately set up leaves divided into booklets with toothed or from time to time smooth edges. The chemical substance inflorescence is an array of several flower minds, or sometimes a solo head. The head has a base covered in layers of phyllaries. The simple row of ray florets are white, yellowish or red; many horticultural specimens have been bred to bear many rows of ray florets in a great variety of colors. The disc florets of wild taxa are orange. The fruit is a ribbed achene. Chrysanthemums, also known as 'mums', are one of the nicest varieties of perennials that start blooming early in the fall. This is also known as favorite flower for the month of November.
Modern cultivated chrysanthemums are showier than their wild relatives. The flower heads occur in various forms, and is daisy-like or decorative, like aigrette or buttons. This genus contains many hybrids and thousands of cultivars developed for horticultural purposes. Besides the traditional yellow, other colors are available, such as white, purple, and red. The most crucial hybrid is Chrysanthemum x morifolium (syn. C. x grandiflorum), derived primarily from C. indicum, but also involving other types.Over 140 varieties of chrysanthemum have gained the Royal Horticultural Society's Honor of Garden Merit.
Chrysanthemums are split up into two basic groups, garden hardy and exhibition. Garden hardy mums are new perennials capable of wintering in most northern latitudes. Exhibition types are not usually as sturdy. Garden hardies are defined by their capacity to produce an abundance of small blooms with little if any mechanical assistance, such as staking, and withstanding wind and rainfall. Exhibition varieties, though, require staking, overwintering in a relatively dry, cool environment, and sometimes digging in night lights.
The exhibition kinds can be used to create many amazing herb forms, such as large disbudded blooms, spray varieties, and many artistically trained forms, such as thousand-bloom, standard (trees), fans, hanging baskets, topiary, bonsai, and cascades.
Chrysanthemum blooms are divided into 10 different bloom forms by the US National Chrysanthemum Society, Inc., which is in preserving the international distinction system. The bloom forms are defined by the way in which the ray and disk florets are arranged. Chrysanthemum blossoms consist of many specific flowers (florets), each one capable of producing a seeds. The disk florets are in the center of the bloom head, and the ray florets are on the perimeter. The ray florets are viewed as imperfect flowers, as they only possess the female effective organs, while the storage florets are considered perfect flowers, as they own both male and feminine reproductive organs.
