Hydrangea (/ha?'dre?nd?i?/;common titles hydrangea or hortensia) is a genus of 70-75 types of flowering vegetation indigenous to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Probably the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters high, but some are small trees and shrubs, among others lianas reaching up to 30 m (98 ft) by climbing up trees and shrubs. They can be either evergreen or deciduous, although cultivated temperate kinds are deciduous greatly.Having been introduced to the Azores, H. macrophylla is very common now, particularly on Faial, which is known as the "blue island" due to the multitude of hydrangeas present on the island.Life cycleHydrangea plants are created from planting season to late fall months; they expand in flowerheads (corymbs or panicles) most often at the ends of the stems.
Typically the flowerheads contain two types of bouquets: small non-showy flowers in the center or interior of the flowerhead, and large, showy blooms with large vibrant sepals (tepals). These showy blooms are lengthened in a engagement ring often, or to the exterior of the small flowers. Crops in wild populations have few to nothing of the showy blossoms typically, while cultivated hydrangeas have been selected and bred to have significantly more of the larger type bouquets.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead blooms are large rounded flowerheads resembling pom-poms or, as the name signifies, the relative mind of the 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 blooms of some rhododendrons and viburnums can seem, initially, very much like those of some hydrangeas.Colors and earth acidityIn most kinds the blooms are white, however in some species (notably H. macrophylla), can be blue, red, red, light crimson, or dark purple. In these kinds the color is damaged by the existence of light weight aluminum ions which can be found or tangled up depending after the soil 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 caused by a color change of the flower pigments in the occurrence of aluminium ions which is often taken up into hyperaccumulating crops.[6] Reducing the pH of potting soils or mixes usually does not change the rose color to blue, because these soils haven't any aluminum ions. The ability to blue or green a hydrangea is also affected 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 most other Hydrangea species is not affected by aluminum and cannot be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
