Hydrangea (/ha?'dre?nd?i?/;common brands hydrangea or hortensia) is a genus of 70-75 species of flowering plant life indigenous to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest species diversity is within eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters tall, but some are small trees and shrubs, and more lianas getting up to 30 m (98 ft) by climbing up trees and shrubs. They can be either evergreen or deciduous, although cultivated temperate kinds are all deciduous broadly.Having been introduced to the Azores, H. macrophylla is currently very common, on Faial particularly, which is known as the "blue island" because of the vast number of hydrangeas present on the island.Life cycleHydrangea blossoms are created from early spring to late fall; they grow in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Typically the flowerheads contain two types of blossoms: small non-showy blossoms in the guts or interior of the flowerhead, and large, showy blossoms with large colorful sepals (tepals). These showy bouquets tend to be prolonged in a engagement ring, or to the surface of the small flowers. Plant life in crazy populations routinely have few to nothing of the showy blossoms, while cultivated hydrangeas have been bred and chosen to have 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 spherical flowerheads resembling pom-poms or, as the name implies, the comparative mind of your 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 plants of some viburnums and rhododendrons can appear, initially, similar to those of some hydrangeas.Land and colors acidityIn most varieties the flowers are white, but in some species (notably H. macrophylla), can be blue, red, pink, light purple, or dark purple. In these varieties the colour is influenced by the presence of aluminum ions which can be found or tangled up depending after the dirt 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 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 caused by a color change of the blossom pigments in the existence of aluminium ions which is often adopted into hyperaccumulating vegetation.[6] Cutting down the pH of potting soils or mixes usually will not change the flower 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 others are bred and selected to be red, pink or white. The flower color of all other Hydrangea species is not influenced by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
