Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest kinds diversity is at eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters tall, but some are small trees and shrubs, among others lianas attaining up to 30 m (98 ft) by climbing up trees and shrubs. They could be either evergreen or deciduous, though the cultivated temperate species are deciduous broadly.Having been introduced to the Azores, H. macrophylla is quite typical now, particularly on Faial, which is known as the "blue island" because of the multitude of hydrangeas present on the island.Life cycleHydrangea blossoms are produced from early spring to late fall months; they expand in flowerheads (corymbs or panicles) frequently at the ends of the stems.

Usually the flowerheads contain two types of flowers: small non-showy flowers in the guts or interior of the flowerhead, and large, showy bouquets with large multi-colored sepals (tepals). These showy bouquets are often expanded in a wedding ring, or to the surface of the tiny flowers. Crops in outrageous populations have few to nothing of the showy flowers typically, while cultivated hydrangeas have been decided on and bred to have significantly 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 plants are large spherical flowerheads resembling pom-poms or, as the name suggests, the relative mind of a mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small blooms encircled by outer bands of bigger blossoms having showy tepals or sepals.

The bouquets of some rhododendrons and viburnums can appear, initially, a lot like those of some hydrangeas.Colors and ground acidityIn most kinds the blooms are white, but in some types (notably H. macrophylla), can be blue, red, red, light purple, or dark purple. In these varieties the color is damaged by the existence of metal ions which can be found or tied up depending upon the ground 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 occurrence of aluminium ions which may be taken up into hyperaccumulating plant life.[6] Decreasing the pH of potting soils or mixes usually will not change the flower color to blue, because these soils have no aluminum ions. The capability to blue or green a hydrangea is also inspired by the cultivar. Some plants are selected for their ability to be blued, while some are bred and selected to be red, white or pink. The flower color of all other Hydrangea species is not affected by aluminum and can't be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
