Hydrangea (/ha?'dre?nd?i?/;common labels hydrangea or hortensia) is a genus of 70-75 varieties of flowering crops indigenous to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Certainly the greatest species diversity is eastern Asia, notably China, Japan, and Korea. The majority are shrubs 1 to 3 meters high, but some are small trees and shrubs, and others lianas getting up to 30 m (98 foot) by climbing up trees. They can be either deciduous or evergreen, though the generally cultivated temperate varieties are all deciduous.Having been introduced to the Azores, H. macrophylla is currently very common, particularly on Faial, which is recognized as the "blue island" due to the vast number of hydrangeas present on the island.Life cycleHydrangea bouquets 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 multi-colored sepals (tepals). These showy blossoms are long in a wedding ring often, or to the surface of the small flowers. Crops in outrageous populations typically have few to none of the showy flowers, while cultivated hydrangeas have been selected and bred to have more of the larger type blooms.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which include the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead blooms are large rounded flowerheads resembling pom-poms or, as the name suggests, the relative mind of any mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small bouquets surrounded by outer wedding rings of bigger blossoms having showy tepals or sepals.
The flowers of some viburnums and rhododendrons can look, at first glance, much like those of some hydrangeas.Dirt and colors acidityIn most varieties the blossoms are white, but in some species (notably H. macrophylla), can be blue, red, red, light crimson, or dark purple. In these types the color is afflicted by the presence of aluminium ions which can be found or tied up depending after the garden soil pH. For H. h and macrophylla. serrata cultivars, the flower color can be dependant on 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 caused by a color change of the bloom pigments in the presence of aluminium ions that can be adopted into hyperaccumulating plants.[6] Cutting down 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 inspired by the cultivar also. Some plants are selected for their 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 affected by aluminum and cannot be changed or shifted. Hydrangeas likewise have a nickname called 'Change Rose'.
