Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 species of flowering crops native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Undoubtedly the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters high, however, many are small trees and shrubs, among others lianas attaining up to 30 m (98 foot) by climbing up trees and shrubs. They could be either deciduous or evergreen, though the greatly cultivated temperate kinds are all deciduous.Having been introduced to the Azores, H. macrophylla is quite typical now, particularly on Faial, which is known as the "blue island" due to the vast number of hydrangeas present on the island.Life cycleHydrangea blossoms are produced from planting season to late fall months; they increase in flowerheads (corymbs or panicles) most often at the ends of the stems.
Typically the flowerheads contain two types of flowers: small non-showy bouquets in the guts or interior of the flowerhead, and large, showy blossoms with large colourful sepals (tepals). These showy plants are prolonged in a wedding ring often, or to the exterior of the tiny flowers. Crops in outdoors populations routinely have few to nothing of the showy plants, while cultivated hydrangeas have been bred and chosen to have significantly more of the bigger type bouquets.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead blooms are large circular flowerheads resembling pom-poms or, as the name implies, the comparative head of the mop. In contrast, lacecap flowers bear round, flat flowerheads with a center core of subdued, small blossoms bounded by outer rings of larger blooms having showy tepals or sepals.
The blossoms of some viburnums and rhododendrons can look, initially, much like those of some hydrangeas.Soil and colors acidityIn most varieties the flowers are white, but in some kinds (notably H. macrophylla), can be blue, red, pink, light purple, or dark crimson. In these varieties the color is influenced by the occurrence of lightweight aluminum ions which are available or tangled up depending after the soil 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 bring about pink or red flowers.
This is caused by a color change of the flower pigments in the presence of aluminium ions which may be adopted into hyperaccumulating vegetation.[6] Bringing down the pH of potting soils or mixes usually does not change the blossom color to blue, because these soils haven't any aluminum ions. The ability to blue or green 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 all other Hydrangea species is not influenced by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
