Hydrangea (/ha?'dre?nd?i?/;common labels hydrangea or hortensia) is a genus of 70-75 kinds of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest types diversity is at eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters extra tall, however, many are small trees, and others lianas attaining up to 30 m (98 foot) by climbing up trees. They could be either evergreen or deciduous, although greatly cultivated temperate kinds are all deciduous.Having been introduced to the Azores, H. macrophylla is very common now, on Faial particularly, which is known as the "blue island" because of the vast number of hydrangeas present on the island.Life cycleHydrangea bouquets are produced from planting season to late autumn; they develop in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Usually the flowerheads contain two types of plants: small non-showy plants in the center or interior of the flowerhead, and large, showy flowers with large colourful sepals (tepals). These showy blossoms tend to be lengthened in a engagement ring, or to the exterior of the tiny flowers. Plant life in outdoors populations have few to none of them of the showy flowers typically, while cultivated hydrangeas have been preferred and bred to have more of the bigger type blossoms.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead blossoms are large circular flowerheads resembling pom-poms or, as the name implies, the head of any mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small bouquets surrounded by outer rings of larger plants having showy tepals or sepals.
The blooms of some viburnums and rhododendrons can appear, initially, much like those of some hydrangeas.Dirt and colors acidityIn most varieties the blossoms are white, however in some species (notably H. macrophylla), can be blue, red, pink, light crimson, or dark crimson. In these types the colour is influenced by the presence of aluminium ions which are available or tied up depending upon the ground 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 produce flowers that are blue to purple typically, whereas an alkaline soil (pH above 7) will tie up aluminum ions and result in pink or red flowers.
This is the effect of a color change of the rose pigments in the presence of aluminium ions which is often taken up into hyperaccumulating plants.[6] Reducing the pH of potting soils or mixes usually will not change the blossom color to blue, because these soils have no aluminum ions. The ability to blue or pink a hydrangea is influenced by the cultivar also. Some plants are selected because of their ability to be blued, while some are bred and selected to be red, pink or white. The flower color of all other Hydrangea species is not affected by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
