Hydrangea (/ha?'dre?nd?i?/;common labels 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. Undoubtedly the greatest varieties diversity is at eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters high, however, many are small trees and shrubs, among others lianas attaining up to 30 m (98 feet) by climbing up trees and shrubs. They can be either deciduous or evergreen, although extensively cultivated temperate types are all deciduous.Having been introduced to the Azores, H. macrophylla is now very common, on Faial particularly, which is recognized as the "blue island" because of the multitude of hydrangeas present on the island.Life cycleHydrangea plants 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 blossoms in the center or interior of the flowerhead, and large, showy bouquets with large brilliant sepals (tepals). These showy flowers are lengthened in a engagement ring often, or to the surface of the tiny flowers. Plants in outdoors populations typically have few to none of them of the showy blooms, while cultivated hydrangeas have been bred and selected to have 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 signifies, the mind of a mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small flowers surrounded by outer bands of larger blossoms having showy tepals or sepals.
The blossoms of some rhododendrons and viburnums can appear, at first glance, just like those of some hydrangeas.Colors and ground 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 kinds the color is damaged by the presence of light weight aluminum ions which are available or tangled up depending upon the ground pH. For H. h and macrophylla. 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 typically produce flowers that are blue to purple, whereas an alkaline soil (pH above 7) will tie up aluminum ions and lead to pink or red flowers.
This is caused by a color change of the flower pigments in the existence of aluminium ions which is often adopted into hyperaccumulating plant life.[6] Bringing down the pH of potting soils or mixes usually will not change the flower color to blue, because these soils haven't any aluminum ions. The ability to blue or green a hydrangea is also inspired by the cultivar. Some plants are selected for his or her 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 can't be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
