Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 types of flowering vegetation native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Probably the greatest kinds diversity is eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters large, but some are small trees, and others lianas reaching up to 30 m (98 feet) by climbing up trees and shrubs. They could be either deciduous or evergreen, although extensively cultivated temperate varieties are deciduous.Having been introduced to the Azores, H. macrophylla is very common now, particularly on Faial, which is known as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea bouquets are created from early spring to late fall; they grow in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Typically the flowerheads contain two types of blossoms: small non-showy flowers in the guts or interior of the flowerhead, and large, showy blooms with large brilliant sepals (tepals). These showy blossoms are lengthened in a engagement ring often, or to the surface of the tiny flowers. Crops in outrageous populations routinely have few to nothing of the showy bouquets, while cultivated hydrangeas have been bred and preferred to have more of the larger type bouquets.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead blooms are large rounded flowerheads resembling pom-poms or, as the name implies, the head of your mop. In contrast, lacecap flowers bear round, flat flowerheads with a center core of subdued, small bouquets ornamented by outer jewelry of bigger bouquets having showy tepals or sepals.
The blooms of some viburnums and rhododendrons can seem, at first glance, just like those of some hydrangeas.Land and colors acidityIn most varieties the blooms are white, but in some varieties (notably H. macrophylla), can be blue, red, red, light purple, or dark crimson. In these varieties the colour is damaged by the occurrence of aluminium ions which can be found or tied up depending upon the land pH. For H. macrophylla and H. serrata cultivars, the flower color can be dependant on 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 bring about pink or red flowers.
This is caused by a color change of the bloom pigments in the existence of aluminium ions which can be taken up into hyperaccumulating plant life.[6] Decreasing the pH of potting soils or mixes usually does not change the blossom color to blue, because these soils haven't any aluminum ions. The ability to blue or green a hydrangea is influenced by the cultivar also. 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 most other Hydrangea species is not affected by aluminum and cannot be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
