Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 kinds of flowering plants local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Certainly the greatest species diversity is within eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters extra tall, however, many are small trees and shrubs, yet others lianas getting up to 30 m (98 foot) by climbing up trees and shrubs. They could be either deciduous or evergreen, though the extensively cultivated temperate varieties are all deciduous.Having been introduced to the Azores, H. macrophylla is quite typical now, on Faial particularly, which is recognized as the "blue island" because of the vast number of hydrangeas present on the island.Life cycleHydrangea blossoms are created from early spring to late fall; they develop in flowerheads (corymbs or panicles) most often at the ends of the stems.
Usually the flowerheads contain two types of blossoms: small non-showy blooms in the guts or interior of the flowerhead, and large, showy blossoms with large brilliant sepals (tepals). These showy bouquets are expanded in a engagement ring often, or to the exterior of the tiny flowers. Plant life in crazy populations routinely have few to nothing of the showy blooms, while cultivated hydrangeas have been chosen and bred to have more of the bigger type blossoms.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead flowers are large circular flowerheads resembling pom-poms or, as the name signifies, the relative head of any mop. On the other hand, 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 blooms of some viburnums and rhododendrons can look, initially, similar to those of some hydrangeas.Soil and colors acidityIn most kinds the plants are white, however in some varieties (notably H. macrophylla), can be blue, red, red, light purple, or dark crimson. In these species the color is damaged by the existence of aluminum ions which can be found or tied up depending upon the earth 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 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 caused by a color change of the bloom pigments in the occurrence of aluminium ions which can be adopted into hyperaccumulating vegetation.[6] Bringing down 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 pink a hydrangea is also influenced by the cultivar. 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 afflicted by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
