Hydrangea (/ha?'dre?nd?i?/;common brands 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 types diversity is eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees and shrubs, and more lianas achieving up to 30 m (98 foot) by climbing up trees. They could be either deciduous or evergreen, though the cultivated temperate kinds are all deciduous widely.Having been introduced to the Azores, H. macrophylla is quite typical now, particularly on Faial, which is recognized as the "blue island" because of the multitude of hydrangeas present on the island.Life cycleHydrangea flowers are produced from planting season to late autumn; they increase in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Typically the flowerheads contain two types of bouquets: small non-showy bouquets in the guts or interior of the flowerhead, and large, showy blossoms with large bright colored sepals (tepals). These showy blooms are often expanded in a band, or to the exterior of the small flowers. Crops in untamed populations typically have few to none of them of the showy bouquets, while cultivated hydrangeas have been picked and bred to have significantly more of the larger type bouquets.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 means, the brain 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 flowers of some rhododendrons and viburnums can look, at first glance, a lot like those of some hydrangeas.Colors and garden soil acidityIn most species the blooms are white, but in some varieties (notably H. macrophylla), can be blue, red, red, light purple, or dark purple. In these varieties the colour is damaged by the presence of aluminium ions which are available or tangled up depending after the dirt 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 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 is often adopted into hyperaccumulating crops.[6] Reducing the pH of potting soils or mixes usually does not change the rose color to blue, because these soils haven't any aluminum ions. The capability to blue or green a hydrangea is also affected 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 most other Hydrangea species is not affected by aluminum and can't be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
