Hydrangea (/ha?'dre?nd?i?/;common brands hydrangea or hortensia) is a genus of 70-75 kinds of flowering crops local to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Probably the greatest kinds diversity is at eastern Asia, china notably, Japan, and Korea. Most are shrubs 1 to 3 meters large, however, many are small trees and shrubs, while others lianas getting up to 30 m (98 ft) by climbing up trees and shrubs. They can be either evergreen or deciduous, though the cultivated temperate types are deciduous broadly.Having been introduced to the Azores, H. macrophylla is now very common, on Faial particularly, which is recognized as the "blue island" because of the vast number of hydrangeas present on the island.Life cycleHydrangea blooms are produced from planting season to late fall; they develop in flowerheads (corymbs or panicles) most often at the ends of the stems.
Usually the flowerheads contain two types of blossoms: small non-showy plants in the center or interior of the flowerhead, and large, showy blossoms with large bright colored sepals (tepals). These showy bouquets are often expanded in a band, or to the exterior of the tiny flowers. Crops in crazy populations have few to none of them of the showy bouquets typically, while cultivated hydrangeas have been picked and bred to have significantly more of the bigger 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 round flowerheads resembling pom-poms or, as the name implies, the relative head of the mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small flowers ornamented by outer bands of greater flowers having showy tepals or sepals.
The blossoms of some rhododendrons and viburnums can appear, initially, just like those of some hydrangeas.Garden soil and colors acidityIn most varieties the flowers are white, however in some varieties (notably H. macrophylla), can be blue, red, green, light crimson, or dark purple. In these types the colour is influenced by the presence of metal ions which can be found or tied up depending upon the earth pH. For H. macrophylla and H. serrata cultivars, the flower color can be determined by 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 lead to pink or red flowers.
This is the effect of a color change of the bloom pigments in the existence of aluminium ions that can be taken up into hyperaccumulating plants.[6] Decreasing 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 influenced by the cultivar. Some plants are selected for his or her ability to be blued, while some are bred and selected to be red, pink or white. The flower color of most other Hydrangea species is not affected by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
