Hydrangea (/ha?'dre?nd?i?/;common brands hydrangea or hortensia) is a genus of 70-75 kinds of flowering crops indigenous to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest kinds diversity is eastern Asia, china notably, Japan, and Korea. Most are shrubs 1 to 3 meters high, but some are small trees and shrubs, among others lianas reaching up to 30 m (98 feet) by climbing up trees and shrubs. They can be either deciduous or evergreen, although generally cultivated temperate species are deciduous.Having been introduced to the Azores, H. macrophylla is quite typical now, on Faial particularly, which is recognized as the "blue island" because of the vast number of hydrangeas present on the island.Life cycleHydrangea bouquets are produced from early spring to late autumn; they increase in flowerheads (corymbs or panicles) most often at the ends of the stems.

Usually the flowerheads contain two types of blossoms: small non-showy flowers in the guts or interior of the flowerhead, and large, showy blossoms with large colorful sepals (tepals). These showy blooms are often extended in a diamond ring, or to the surface of the small flowers. Vegetation in outdoors populations have few to none of them of the showy flowers typically, while cultivated hydrangeas have been bred and selected to have more of the larger type plants.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead bouquets are large circular flowerheads resembling pom-poms or, as the name means, the brain of any 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 seem, at first glance, just like those of some hydrangeas.Soil and colors acidityIn most varieties the plants are white, but in some types (notably H. macrophylla), can be blue, red, green, light crimson, or dark purple. In these species the color is affected by the existence of light weight 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 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 lead to pink or red flowers.

This is the effect of a color change of the flower pigments in the occurrence of aluminium ions which may be adopted into hyperaccumulating plants.[6] Bringing down the pH of potting soils or mixes usually does not change the rose color to blue, because these soils have no aluminum ions. The capability to blue or pink a hydrangea is also inspired by the cultivar. Some plants are selected for his or her 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 influenced by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
