Hydrangea (/ha?'dre?nd?i?/;common brands hydrangea or hortensia) is a genus of 70-75 species of flowering plant life native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Probably the greatest kinds diversity is eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters extra tall, but some are small trees and shrubs, while others lianas getting up to 30 m (98 feet) by climbing up trees and shrubs. They could be either evergreen or deciduous, although broadly cultivated temperate varieties are deciduous.Having been introduced to the Azores, H. macrophylla is currently very common, 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 autumn; they expand in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Usually the flowerheads contain two types of flowers: small non-showy plants in the center or interior of the flowerhead, and large, showy blossoms with large vibrant sepals (tepals). These showy flowers tend to be lengthened in a diamond ring, or to the exterior of the small flowers. Vegetation in wild populations typically have few to none of the showy plants, while cultivated hydrangeas have been bred and preferred to have significantly more of the larger type blooms.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 signifies, the comparative brain of any mop. In contrast, lacecap flowers bear round, flat flowerheads with a center core of subdued, small plants surrounded by outer jewelry of bigger blossoms having showy tepals or sepals.
The blooms of some rhododendrons and viburnums can look, initially, comparable to those of some hydrangeas.Colors and earth acidityIn most types the blooms are white, but in some types (notably H. macrophylla), can be blue, red, red, light purple, or dark purple. In these varieties the colour is influenced by the existence of aluminium ions which are available or tied up depending after the earth pH. For H. h and macrophylla. serrata cultivars, the flower color can be determined by 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 cause pink or red flowers.
This is caused by a color change of the flower pigments in the occurrence of aluminium ions which may be taken up into hyperaccumulating plant life.[6] Reducing the pH of potting soils or mixes usually will not change the bloom color to blue, because these soils haven't any aluminum ions. The capability to blue or pink a hydrangea is inspired by the cultivar also. 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 affected by aluminum and cannot be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
