Hydrangea (/ha?'dre?nd?i?/;common labels hydrangea or hortensia) is a genus of 70-75 types of flowering vegetation indigenous 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, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters large, however, many are small trees and shrubs, and others lianas reaching up to 30 m (98 feet) by climbing up trees and shrubs. They could be either evergreen or deciduous, though the cultivated temperate species are all deciduous generally.Having been introduced to the Azores, H. macrophylla is currently very common, on Faial particularly, which is recognized as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea blossoms are produced from early spring to late fall; they grow in flowerheads (corymbs or panicles) most often at the ends of the stems.
Usually the flowerheads contain two types of blooms: small non-showy blooms in the guts or interior of the flowerhead, and large, showy blooms with large colorful sepals (tepals). These showy flowers tend to be expanded in a diamond ring, or to the surface of the small flowers. Vegetation in outdoors populations have few to nothing of the showy flowers typically, while cultivated hydrangeas have been preferred and bred to have significantly more of the larger type plants.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead plants are large round flowerheads resembling pom-poms or, as the name indicates, the comparative brain 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 blossoms of some viburnums and rhododendrons can seem, initially, comparable to those of some hydrangeas.Ground and colors acidityIn most types the bouquets are white, but in some species (notably H. macrophylla), can be blue, red, pink, light purple, or dark crimson. In these kinds the color is affected by the occurrence of metal ions which are available or tangled up depending after the earth pH. For H. macrophylla and H. serrata cultivars, the flower color can be determined by 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 bring about pink or red flowers.
This is the effect of a color change of the rose pigments in the occurrence of aluminium ions which can be taken up into hyperaccumulating plants.[6] Lowering the pH of potting soils or mixes usually does not change the bloom color to blue, because these soils haven't any aluminum ions. The capability 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, pink or white. The flower color of most other Hydrangea species is not affected by aluminum and cannot be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
