Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 species of flowering plant life local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest varieties diversity is in eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters extra tall, but some are small trees and shrubs, while others lianas reaching up to 30 m (98 feet) by climbing up trees. They could be either evergreen or deciduous, although extensively cultivated temperate species are all deciduous.Having been introduced to the Azores, H. macrophylla is now very common, particularly on Faial, which is recognized as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea flowers are produced from early spring to late autumn; they increase in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Usually the flowerheads contain two types of flowers: small non-showy flowers in the guts or interior of the flowerhead, and large, showy blooms with large multi-colored sepals (tepals). These showy bouquets are prolonged in a wedding ring often, or to the surface of the small flowers. Plants in untamed populations have few to nothing of the showy plants typically, while cultivated hydrangeas have been selected and bred to have more of the bigger type blooms.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead plants are large rounded flowerheads resembling pom-poms or, as the name signifies, the mind of any mop. In contrast, 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 viburnums and rhododendrons can appear, initially, a lot like those of some hydrangeas.Colors and dirt acidityIn most varieties the flowers are white, but in some types (notably H. macrophylla), can be blue, red, pink, light crimson, or dark crimson. In these varieties the color is damaged by the existence of aluminum ions which are available or tied up depending after the soil 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 lead to pink or red flowers.
This is the effect of a color change of the blossom pigments in the occurrence of aluminium ions which may be adopted into hyperaccumulating plant life.[6] Lowering 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 affected by the cultivar also. Some plants are selected for their 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 influenced by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
