Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 types of flowering crops indigenous to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Probably the greatest types diversity is eastern Asia, china notably, Japan, and Korea. The majority are shrubs 1 to 3 meters high, however, many are small trees and shrubs, yet others lianas achieving up to 30 m (98 feet) by climbing up trees. They could be either deciduous or evergreen, although cultivated temperate kinds are deciduous widely.Having been introduced to the Azores, H. macrophylla is quite typical now, particularly on Faial, which is recognized as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea bouquets are produced from planting season to late autumn; they grow in flowerheads (corymbs or panicles) most often at the ends of the stems.
Typically the flowerheads contain two types of flowers: small non-showy plants in the guts or interior of the flowerhead, and large, showy plants with large vibrant sepals (tepals). These showy plants tend to be long in a engagement ring, or to the exterior of the small flowers. Plant life in outdoors populations have few to nothing of the showy flowers typically, while cultivated hydrangeas have been bred and determined to have more of the bigger 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 round flowerheads resembling pom-poms or, as the name means, the brain of the mop. In contrast, lacecap flowers bear round, flat flowerheads with a center core of subdued, small blossoms bounded by outer bands of greater plants having showy tepals or sepals.
The blooms of some rhododendrons and viburnums can seem, at first glance, just like those of some hydrangeas.Colors and ground acidityIn most types the bouquets are white, however in some types (notably H. macrophylla), can be blue, red, red, light crimson, or dark crimson. In these types the colour is influenced by the presence of metal ions which are available or tangled up depending upon the soil 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 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 lead to pink or red flowers.
This is caused by a color change of the flower pigments in the presence of aluminium ions which can be taken up into hyperaccumulating plant life.[6] Decreasing the pH of potting soils or mixes usually will not change the rose color to blue, because these soils have no aluminum ions. The ability to blue or pink a hydrangea is affected by the cultivar also. Some plants are selected for his or her ability to be blued, while others are bred and selected to be red, white or pink. The flower color of most other Hydrangea species is not affected by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
