Chrysanthemums, sometimes called mums or chrysanths, are flowering plants of the genus Chrysanthemum in the family Asteraceae. They are native to Asia and northeastern European countries. 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 language:?????? chrysos (gold) and Ancient Greek:??????? anthemon (flower).

Taxonomy

The genus once included more species, unfortunately he break up 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 utilized in the genus Glebionis. The other genera separate from Chrysanthemum include Argyranthemum, Leucanthemopsis, Leucanthemum, Rhodanthemum, and Tanacetum.

Description

Crazy Chrysanthemum taxa are herbaceous perennial plants or subshrubs. They have alternately arranged leaves divided into leaflets with toothed or sometimes smooth edges. The chemical substance inflorescence is an mixture of several flower minds, or sometimes a solitary head. The head has a base covered in layers of phyllaries. The simple row of beam florets are white, orange or red; many horticultural specimens have been carefully bred to bear many lanes 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 prettiest varieties of perennials that start blooming early in the fall. This is also known as favorite flower for the month of November.

Modern grown 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. In addition to the traditional yellow, other colors are available, such as white, purple, and red. The main 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 broken into two basic groups, garden hardy and exhibition. Garden hardy mothers are new perennials in a position of wintering in most northern latitudes. Exhibition types are not usually as sturdy. Garden hardies are defined by their ability to generate an abundance of small blooms with little if any mechanical assistance, such as staking, and withstanding wind and rainwater. Exhibition varieties, though, require staking, overwintering in a relatively dry, cool environment, and sometimes the addition of night time lights.

The exhibition varieties can be used to create many amazing flower forms, such as large disbudded blooms, spray forms, and many artistically trained forms, such as thousand-bloom, standard (trees), fans, dangling baskets, topiary, bonsai, and cascades.

Chrysanthemum blooms are divided into 10 different bloom forms by the US National Chrysanthemum World, Inc., which is in keeping with the international distinction system. The bloom varieties are defined by the way in which the ray and disk florets are arranged. Chrysanthemum blooms are composed of many individual 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 considered not perfect flowers, as they only possess the female successful organs, while the disk florets are considered perfect flowers, as they have both male and female reproductive organs.

Hydrangea (/ha?'dre?nd?i?/;common brands hydrangea or hortensia) is a genus of 70-75 species of flowering plants local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Undoubtedly the greatest varieties diversity is within eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters large, however, many are small trees, and more lianas attaining up to 30 m (98 foot) by climbing up trees and shrubs. They could be either deciduous or evergreen, although cultivated temperate types are all deciduous extensively.Having been introduced to the Azores, H. macrophylla is quite typical now, particularly on Faial, which is known as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea plants are created from planting season to late fall months; they increase in flowerheads (corymbs or panicles) most often at the ends of the stems.

Typically the flowerheads contain two types of blooms: small non-showy blossoms in the guts or interior of the flowerhead, and large, showy blossoms with large multi-colored sepals (tepals). These showy blooms are often expanded in a ring, or to the exterior of the small flowers. Vegetation in untamed populations have few to none of them of the showy plants typically, while cultivated hydrangeas have been bred and selected to have significantly more of the larger type plants.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead flowers are large round flowerheads resembling pom-poms or, as the name indicates, the mind of an mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small flowers surrounded by outer rings of larger flowers having showy sepals or tepals.

The plants of some rhododendrons and viburnums can show up, initially, a lot like those of some hydrangeas.Ground and colors acidityIn most species the blooms are white, but in some species (notably H. macrophylla), can be blue, red, green, light purple, or dark crimson. In these varieties the color is damaged by the existence of aluminium ions which can be found or tangled up depending after the ground pH. For H. macrophylla and H. serrata cultivars, the flower color can be dependant on the relative acidity of the soil: an acidic soil (pH below 7), will have available aluminum ions and typically produce flowers that are blue to purple, whereas an alkaline soil (pH above 7) will tie up aluminum ions and lead to pink or red flowers.

This is caused by a color change of the flower pigments in the existence of aluminium ions which is often adopted into hyperaccumulating plants.[6] Minimizing the pH of potting soils or mixes usually will not change the flower color to blue, because these soils have no aluminum ions. The capability to blue or green a hydrangea is inspired by the cultivar also. Some plants are selected for his or her ability to be blued, while others are bred and selected to be red, white or pink. The flower color of all other Hydrangea species is not afflicted by aluminum and can't be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
