Hydrangea (/ha?'dre?nd?i?/;common brands hydrangea or hortensia) is a genus of 70-75 varieties of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Undoubtedly 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, among others lianas attaining up to 30 m (98 foot) by climbing up trees and shrubs. They could be either deciduous or evergreen, though the generally cultivated temperate varieties are all deciduous.Having been introduced to the Azores, H. macrophylla is quite typical now, on Faial particularly, which is known as the "blue island" because of the vast number of hydrangeas present on the island.Life cycleHydrangea plants are produced from planting season to late fall months; they grow in flowerheads (corymbs or panicles) frequently at the ends of the stems.
Usually the flowerheads contain two types of bouquets: small non-showy plants in the center or interior of the flowerhead, and large, showy flowers with large vibrant sepals (tepals). These showy blooms are long in a band often, or to the surface of the tiny flowers. Vegetation in outrageous populations typically have few to none of the showy bouquets, while cultivated hydrangeas have been bred and chosen to have 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 blossoms are large round flowerheads resembling pom-poms or, as the name signifies, the mind of your mop. On the other hand, lacecap flowers bear round, flat flowerheads with a center core of subdued, small blooms surrounded by outer rings of bigger blossoms having showy tepals or sepals.
The blossoms of some rhododendrons and viburnums can seem, initially, comparable to those of some hydrangeas.Colors and soil acidityIn most types the plants are white, but in some types (notably H. macrophylla), can be blue, red, pink, light crimson, or dark purple. In these kinds the color is damaged by the occurrence of lightweight aluminum ions which are available or tied up depending after the land 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 typically produce flowers that are blue to purple, whereas an alkaline soil (pH above 7) will tie up aluminum ions and bring about pink or red flowers.
This is caused by a color change of the blossom pigments in the presence of aluminium ions which can be adopted into hyperaccumulating plant life.[6] Cutting down the pH of potting soils or mixes usually does 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 his or her ability to be blued, while some are bred and selected to be red, pink or white. The flower color of all other Hydrangea species is not affected by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
