Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 types of flowering vegetation indigenous to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Probably the greatest kinds diversity is within eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters high, however, many are small trees, among others lianas attaining up to 30 m (98 ft) by climbing up trees and shrubs. They could be either deciduous or evergreen, though the cultivated temperate kinds are deciduous broadly.Having been introduced to the Azores, H. macrophylla is now very common, on Faial particularly, which is known as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea flowers are produced from early spring to late fall; they expand in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Typically the flowerheads contain two types of blossoms: small non-showy plants in the guts or interior of the flowerhead, and large, showy bouquets with large multi-colored sepals (tepals). These showy flowers are often prolonged in a wedding ring, or to the surface of the small flowers. Plants in crazy populations typically have few to none of the showy blossoms, while cultivated hydrangeas have been bred and determined to have more of the larger type blossoms.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead plants are large rounded flowerheads resembling pom-poms or, as the name suggests, the relative mind of the mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small bouquets surrounded by outer rings of bigger flowers having showy tepals or sepals.
The blooms of some rhododendrons and viburnums can show up, at first glance, very much like those of some hydrangeas.Earth and colors acidityIn most species the plants are white, but in some kinds (notably H. macrophylla), can be blue, red, green, light purple, or dark purple. In these species the colour is influenced by the presence of metal ions which are available or tangled up depending upon 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 lead to 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 adopted into hyperaccumulating crops.[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 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 others are bred and selected to be red, pink or white. 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'.
