Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 varieties of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Probably the greatest types diversity is within eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters large, but some are small trees, while others lianas reaching up to 30 m (98 feet) by climbing up trees and shrubs. They could be either evergreen or deciduous, though the cultivated temperate species are all deciduous widely.Having been introduced to the Azores, H. macrophylla is very common now, particularly on Faial, which is recognized as the "blue island" because of the vast number of hydrangeas present on the island.Life cycleHydrangea blooms are produced from early spring to late fall months; they expand in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Usually the flowerheads contain two types of bouquets: small non-showy plants in the guts or interior of the flowerhead, and large, showy blooms with large vibrant sepals (tepals). These showy bouquets are often long in a ring, or to the exterior of the tiny flowers. Plants in crazy populations have few to none of them of the showy plants typically, while cultivated hydrangeas have been picked and bred 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 flowers are large rounded flowerheads resembling pom-poms or, as the name indicates, the relative brain of a 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 rhododendrons and viburnums can show up, at first glance, a lot like those of some hydrangeas.Colors and dirt acidityIn most types the blossoms are white, but in some varieties (notably H. macrophylla), can be blue, red, green, light crimson, or dark crimson. In these kinds the color is damaged 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 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 rose pigments in the occurrence of aluminium ions which can be taken up into hyperaccumulating vegetation.[6] Cutting 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 capability to blue or green a hydrangea is also influenced by the cultivar. Some plants are selected for their 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 likewise have a nickname called 'Change Rose'.
