Hydrangea (/ha?'dre?nd?i?/;common names hydrangea or hortensia) is a genus of 70-75 types of flowering vegetation native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Definitely the greatest kinds diversity is within eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters extra tall, however, many are small trees and shrubs, and more lianas reaching up to 30 m (98 feet) by climbing up trees and shrubs. They can be either deciduous or evergreen, though the cultivated temperate species are deciduous generally.Having been introduced to the Azores, H. macrophylla is currently very common, on Faial particularly, which is known as the "blue island" due to the vast number of hydrangeas present on the island.Life cycleHydrangea flowers are produced from early spring to late fall months; they develop in flowerheads (corymbs or panicles) most often at the ends of the stems.
Typically the flowerheads contain two types of blossoms: small non-showy bouquets in the center or interior of the flowerhead, and large, showy blossoms with large vibrant sepals (tepals). These showy bouquets are long in a band often, or to the exterior of the tiny flowers. Crops in wild populations typically have few to nothing of the showy flowers, while cultivated hydrangeas have been bred and picked to have 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 blossoms are large rounded flowerheads resembling pom-poms or, as the name means, the head of an 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 blooms of some rhododendrons and viburnums can seem, at first glance, just like those of some hydrangeas.Colors and soil acidityIn most kinds the blooms are white, however in some kinds (notably H. macrophylla), can be blue, red, green, light crimson, or dark purple. In these kinds the color is affected by the presence of light weight aluminum ions which are available or tied up depending after the dirt pH. For H. macrophylla and H. serrata cultivars, the flower color can be dependant on the relative acidity of the soil: an acidic soil (pH below 7), will have available 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 the effect of a color change of the bloom pigments in the presence of aluminium ions which can be taken up into hyperaccumulating vegetation.[6] Reducing the pH of potting soils or mixes usually will not change the bloom 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 others 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'.
