Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 types of flowering plant life native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Undoubtedly the greatest varieties diversity is at eastern Asia, china notably, Japan, and Korea. Most are shrubs 1 to 3 meters high, but some are small trees and shrubs, yet others lianas achieving up to 30 m (98 ft) by climbing up trees and shrubs. They could be either evergreen or deciduous, although cultivated temperate types are deciduous broadly.Having been introduced to the Azores, H. macrophylla is currently very common, on Faial particularly, which is recognized as the "blue island" because of the multitude of hydrangeas present on the island.Life cycleHydrangea blooms are created 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 blooms: small non-showy blossoms in the center or interior of the flowerhead, and large, showy blooms with large colourful sepals (tepals). These showy plants are often prolonged in a diamond ring, or to the surface of the tiny flowers. Plants in untamed populations typically have few to none of the showy blooms, while cultivated hydrangeas have been determined and bred to have significantly more of the larger 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 circular flowerheads resembling pom-poms or, as the name implies, the relative mind of any mop. In contrast, lacecap flowers bear round, flat flowerheads with a center core of subdued, small bouquets encircled by outer bands of much larger plants having showy tepals or sepals.
The flowers of some rhododendrons and viburnums can appear, at first glance, comparable to those of some hydrangeas.Colors and land acidityIn most types the blossoms are white, but in some varieties (notably H. macrophylla), can be blue, red, red, light purple, or dark purple. In these species the color is influenced by the presence of aluminum ions which can be found 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 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 bloom pigments in the existence of aluminium ions which may be adopted into hyperaccumulating vegetation.[6] Cutting down the pH of potting soils or mixes usually does not change the flower color to blue, because these soils have no aluminum ions. The capability to blue or green a hydrangea is inspired by the cultivar also. 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 influenced by aluminum and can't be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
