Hydrangea (/ha?'dre?nd?i?/;common names 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 species diversity is in eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters large, but some are small trees and shrubs, while others lianas reaching up to 30 m (98 ft) by climbing up trees. They can be either deciduous or evergreen, although cultivated temperate species are deciduous greatly.Having been introduced to the Azores, H. macrophylla is now very common, particularly on Faial, which is recognized as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea plants are created from planting season to late fall; they develop in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Typically the flowerheads contain two types of bouquets: small non-showy blooms in the guts or interior of the flowerhead, and large, showy blooms with large vibrant sepals (tepals). These showy bouquets tend to be extended in a engagement ring, or to the surface of the tiny flowers. Plant life in outdoors populations have few to none of the showy plants typically, while cultivated hydrangeas have been bred and chosen to have more of the bigger type blossoms.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead flowers are large rounded flowerheads resembling pom-poms or, as the name indicates, the mind of any 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 blossoms of some viburnums and rhododendrons can look, initially, a lot like those of some hydrangeas.Soil and colors acidityIn most types the blooms are white, but in some varieties (notably H. macrophylla), can be blue, red, green, light crimson, or dark crimson. In these kinds the colour is influenced by the existence of aluminum ions which are available or tangled up depending after the dirt 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 supply 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 blossom pigments in the existence of aluminium ions which may be taken up into hyperaccumulating vegetation.[6] Lowering the pH of potting soils or mixes usually will not change the blossom color to blue, because these soils have no aluminum ions. The capability to blue or pink a hydrangea is also affected by the cultivar. Some plants are selected for their 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'.
