Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 types of flowering plant life indigenous to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Undoubtedly the greatest types diversity is within eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters high, however, many are small trees and shrubs, as well as others lianas reaching up to 30 m (98 feet) by climbing up trees. They can 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" due to the vast number of hydrangeas present on the island.Life cycleHydrangea flowers are produced from early spring to late fall months; they develop in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Usually the flowerheads contain two types of blossoms: small non-showy flowers in the center or interior of the flowerhead, and large, showy blooms with large brilliant sepals (tepals). These showy plants are often expanded in a ring, or to the surface of the tiny flowers. Plant life in outrageous populations have few to none of the showy plants typically, while cultivated hydrangeas have been bred and decided on to have more of the larger type flowers.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead flowers are large round flowerheads resembling pom-poms or, as the name indicates, the head of your 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 bouquets of some viburnums and rhododendrons can appear, at first glance, just like those of some hydrangeas.Ground and colors acidityIn most varieties the plants are white, but in some species (notably H. macrophylla), can be blue, red, pink, light crimson, or dark crimson. In these species the colour is damaged by the presence of aluminium ions which are available or tied up depending after the ground 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 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 the effect of a color change of the blossom pigments in the occurrence of aluminium ions which can be taken up into hyperaccumulating plants.[6] Cutting down the pH of potting soils or mixes usually will not change the rose color to blue, because these soils haven't any aluminum ions. The ability to blue or green a hydrangea is also influenced by the cultivar. 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 likewise have a nickname called 'Change Rose'.
