Hydrangea (/ha?'dre?nd?i?/;common brands 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. Certainly the greatest types diversity is at eastern Asia, china notably, Japan, and Korea. Most are shrubs 1 to 3 meters high, however, many are small trees and shrubs, among others lianas achieving up to 30 m (98 foot) by climbing up trees. They can be either evergreen or deciduous, although cultivated temperate species are deciduous widely.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 multitude of hydrangeas present on the island.Life cycleHydrangea plants are produced from planting season to late fall; they increase in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Typically the flowerheads contain two types of plants: small non-showy blossoms in the center or interior of the flowerhead, and large, showy plants with large multi-colored sepals (tepals). These showy flowers tend to be prolonged in a ring, or to the surface of the small flowers. Plant life in wild populations routinely have few to nothing of the showy bouquets, while cultivated hydrangeas have been determined and bred to have more of the larger type plants.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 suggests, the head of any mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small plants surrounded by outer bands of bigger plants having showy tepals or sepals.
The blossoms of some rhododendrons and viburnums can seem, initially, a lot like those of some hydrangeas.Colors and earth acidityIn most types the bouquets are white, but in some species (notably H. macrophylla), can be blue, red, red, light purple, or dark purple. In these species the colour is damaged by the occurrence of aluminum ions which are available or tied up depending upon the land pH. For H. macrophylla and H. serrata cultivars, the flower color can be determined by 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 lead to pink or red flowers.
This is caused by a color change of the bloom pigments in the occurrence of aluminium ions that can be adopted into hyperaccumulating plant life.[6] Cutting 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 ability to blue or green a hydrangea is also inspired by the cultivar. Some plants are selected for his or her ability to be blued, while some are bred and selected to be red, pink or white. The flower color of most other Hydrangea species is not influenced by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
