Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 varieties of flowering vegetation local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Undoubtedly the greatest kinds diversity is eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters high, however, many are small trees, and more lianas achieving up to 30 m (98 foot) by climbing up trees and shrubs. They could be either evergreen or deciduous, although cultivated temperate varieties are deciduous extensively.Having been introduced to the Azores, H. macrophylla is very common now, particularly on Faial, which is known as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea bouquets are produced from early spring 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 plants: small non-showy flowers in the center or interior of the flowerhead, and large, showy bouquets with large multi-colored sepals (tepals). These showy blossoms are prolonged in a ring often, or to the surface of the tiny flowers. Plant life in crazy populations have few to nothing of the showy blooms typically, while cultivated hydrangeas have been bred and preferred to have more of the bigger type bouquets.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead bouquets are large spherical flowerheads resembling pom-poms or, as the name indicates, the mind of a 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 bouquets of some rhododendrons and viburnums can show up, initially, just like those of some hydrangeas.Colors and earth acidityIn most varieties the bouquets are white, however in some kinds (notably H. macrophylla), can be blue, red, pink, light crimson, or dark crimson. In these kinds the colour is damaged by the occurrence of light weight aluminum ions which are available or tangled up depending after the ground pH. For H. h and macrophylla. 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 produce flowers that are blue to purple typically, whereas an alkaline soil (pH above 7) will tie up aluminum ions and result in pink or red flowers.

This is caused by a color change of the bloom pigments in the presence of aluminium ions which may be adopted into hyperaccumulating plants.[6] Decreasing 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 pink a hydrangea is also inspired by the cultivar. Some plants are selected for his or her ability to be blued, while others are bred and selected to be red, pink or white. The flower color of most other Hydrangea species is not damaged by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.

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 countless horticultural varieties and cultivars. The name "chrysanthemum" comes from the Ancient Greek:?????? chrysos (gold) and Old Greek:??????? anthemon (flower).

Taxonomy

The genus once included more species, but was divided several decades ago into several genera, putting the economically important florist's chrysanthemums in the genus Dendranthema. The naming of the genera has been good, 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 previously included in the narrow view of the genus Chrysanthemum are now utilized in the genus Glebionis. The other overal 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 booklets with toothed or occasionally smooth edges. The chemical substance inflorescence is an array of several flower heads, or sometimes an one 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 bred to bear many series of ray florets in a great variety of colors. The disc florets of wild taxa are yellow. The fruit is a ribbed achene. Chrysanthemums, also known as 'mums', are one of the lovliest varieties of perennials that start blooming early in the fall. This is also known as favorite flower for the month of November.

Modern developed chrysanthemums are showier than their wild relatives. The flower heads occur in various forms, and is daisy-like or decorative, like pompons or buttons. This genus contains many hybrids and thousands of cultivars developed for horticultural purposes. As well as 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 mainly from C. indicum, but also involving other varieties.Over 140 varieties of chrysanthemum have gained the Royal Horticultural Society's Honor of Garden Merit.

Chrysanthemums are divided 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 capability to produce an abundance of small blooms with little if any mechanical assistance, such as staking, and withstanding wind and rain. Exhibition varieties, though, require staking, overwintering in a relatively dry, cool environment, and sometimes the addition of night lights.

The exhibition varieties 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, dangling baskets, topiary, bonsai, and cascades.

Chrysanthemum blooms are divided into 10 different bloom forms by the US National Chrysanthemum Society, Inc., which is in keeping with the international category system. The bloom forms are defined by the way in which the ray and disk florets are arranged. Chrysanthemum flowers are composed of many specific flowers (florets), each one capable of producing a seedling. The disk florets are in the center of the bloom head, and the ray florets are on the perimeter. The ray florets are believed imperfect flowers, as they only possess the female effective organs, while the disk florets are considered perfect flowers, as they possess both male and feminine reproductive organs.
