Hydrangea (/ha?'dre?nd?i?/;common labels 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. Definitely the greatest species diversity is at eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters large, but some are small trees, as well as others lianas reaching up to 30 m (98 feet) by climbing up trees and shrubs. They can be either evergreen or deciduous, though the cultivated temperate species are all deciduous widely.Having been introduced to the Azores, H. macrophylla is quite typical now, particularly on Faial, which is recognized as the "blue island" due to the vast number of hydrangeas present on the island.Life cycleHydrangea blooms are created from planting season to late fall months; they expand in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Typically the flowerheads contain two types of blooms: small non-showy blossoms in the guts or interior of the flowerhead, and large, showy flowers with large colourful sepals (tepals). These showy bouquets are often expanded in a diamond ring, or to the surface of the small flowers. Crops in outrageous populations have few to none of the showy blooms typically, while cultivated hydrangeas have been bred and selected to have significantly more of the bigger 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 rounded flowerheads resembling pom-poms or, as the name suggests, the mind of an 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 plants of some rhododendrons and viburnums can look, at first glance, very much like those of some hydrangeas.Colors and dirt acidityIn most species the plants are white, but in some varieties (notably H. macrophylla), can be blue, red, green, light purple, or dark purple. In these varieties the colour is affected by the existence of light weight aluminum ions which are available or tangled up depending after the soil pH. For H. h and macrophylla. serrata cultivars, the flower color can be dependant on 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 cause 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 taken up into hyperaccumulating plants.[6] Bringing down the pH of potting soils or mixes usually does not change the blossom 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, white or pink. The flower color of most other Hydrangea species is not damaged by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
