Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 varieties of flowering plants local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Undoubtedly the greatest types diversity is eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters extra tall, but some are small trees and shrubs, yet others lianas achieving 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 widely.Having been introduced to the Azores, H. macrophylla is currently very common, on Faial particularly, which is recognized as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea bouquets are created from early spring to late fall months; they expand in flowerheads (corymbs or panicles) most often at the ends of the stems.
Typically the flowerheads contain two types of blossoms: small non-showy blooms in the center or interior of the flowerhead, and large, showy plants with large multi-colored sepals (tepals). These showy bouquets are often expanded in a ring, or to the surface of the small flowers. Plants in untamed populations typically have few to none of the showy plants, while cultivated hydrangeas have been chosen and bred to have significantly more of the larger type bouquets.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead flowers are large rounded flowerheads resembling pom-poms or, as the name implies, the relative mind of your mop. On the other hand, 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 bouquets of some viburnums and rhododendrons can appear, initially, very much like those of some hydrangeas.Colors and land acidityIn most varieties the blooms are white, but in some types (notably H. macrophylla), can be blue, red, red, light purple, or dark purple. In these types the colour is damaged by the existence of aluminium ions which are available or tangled up depending upon 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 typically produce flowers that are blue to purple, whereas an alkaline soil (pH above 7) will tie up aluminum ions and result in 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 flower 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 damaged by aluminum and can't be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
