Hydrangea Pics: Hydrangea Pinky Winky.

Hydrangea (/ha?'dre?nd?i?/;common labels hydrangea or hortensia) is a genus of 70-75 types of flowering plant life local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest types diversity is at eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters large, however, many are small trees and shrubs, among others lianas getting up to 30 m (98 foot) by climbing up trees and shrubs. They could be either evergreen or deciduous, although cultivated temperate species are all deciduous widely.Having been introduced to the Azores, H. macrophylla is currently very common, particularly on Faial, which is known as the "blue island" because of 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) frequently at the ends of the stems.

Typically the flowerheads contain two types of plants: small non-showy plants in the guts or interior of the flowerhead, and large, showy plants with large vibrant sepals (tepals). These showy bouquets are extended in a ring often, or to the surface of the tiny flowers. Plants in untamed populations routinely have few to none of them of the showy blooms, while cultivated hydrangeas have been preferred and bred to have significantly more of the larger type bouquets.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead blooms are large circular flowerheads resembling pom-poms or, as the name suggests, the brain of any 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 viburnums and rhododendrons can seem, at first glance, comparable to those of some hydrangeas.Colors and dirt acidityIn most species the plants are white, however in some varieties (notably H. macrophylla), can be blue, red, pink, light purple, or dark crimson. In these types the colour is afflicted by the presence of light weight aluminum ions which can be found or tangled up depending after the earth 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 bring about pink or red flowers.

This is caused by a color change of the flower pigments in the existence of aluminium ions which may be taken up into hyperaccumulating crops.[6] Cutting down the pH of potting soils or mixes usually does not change the blossom color to blue, because these soils haven't any aluminum ions. The ability to blue or pink a hydrangea is also influenced by the cultivar. Some plants are selected for his or her ability to be blued, while some are bred and selected to be red, white or pink. The flower color of all other Hydrangea species is not afflicted by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
