Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 kinds of flowering vegetation local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Certainly the greatest varieties diversity is at eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters extra tall, however, many are small trees and shrubs, while others lianas getting up to 30 m (98 ft) by climbing up trees. They could be either deciduous or evergreen, though the cultivated temperate types 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 bouquets are produced from early spring to late fall; they develop 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 colorful sepals (tepals). These showy flowers are expanded in a wedding ring often, or to the exterior of the tiny flowers. Plants in wild populations routinely have few to none of them of the showy flowers, while cultivated hydrangeas have been preferred and bred to have significantly more of the larger type blossoms.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead plants are large spherical flowerheads resembling pom-poms or, as the name means, the comparative brain of a 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 flowers of some rhododendrons and viburnums can show up, initially, a lot like those of some hydrangeas.Colors and ground acidityIn most types the blossoms are white, however in some types (notably H. macrophylla), can be blue, red, green, light crimson, or dark crimson. In these varieties the colour is influenced by the presence of lightweight aluminum ions which are available or tangled up depending after the dirt 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 supply 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 the effect of a color change of the rose pigments in the existence of aluminium ions that can be adopted into hyperaccumulating crops.[6] Minimizing the pH of potting soils or mixes usually will not change the bloom color to blue, because these soils have no aluminum ions. The ability to blue or green a hydrangea is influenced by the cultivar also. Some plants are selected for their 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 damaged by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
