Hydrangea (/ha?'dre?nd?i?/;common labels hydrangea or hortensia) is a genus of 70-75 varieties of flowering plant life native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. Certainly the greatest kinds diversity is at eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters extra tall, but some are small trees and shrubs, yet others lianas reaching up to 30 m (98 feet) by climbing up trees. They can be either deciduous or evergreen, though the broadly cultivated temperate varieties are deciduous.Having been introduced to the Azores, H. macrophylla is very common now, on Faial particularly, which is recognized as the "blue island" because of the multitude of hydrangeas present on the island.Life cycleHydrangea blossoms are produced from early spring to late autumn; they expand in flowerheads (corymbs or panicles) most often at the ends of the stems.

Usually the flowerheads contain two types of plants: small non-showy blooms in the guts or interior of the flowerhead, and large, showy plants with large vibrant sepals (tepals). These showy bouquets are prolonged in a ring often, or to the exterior of the small flowers. Vegetation in outrageous populations have few to none of the showy blossoms typically, while cultivated hydrangeas have been bred and chosen to have significantly more of the larger type plants.There are two flower arrangements in hydrangeas with Corymb style inflorescens, which includes the commonly grown "bigleaf hydrangea"--Hydrangea macrophylla. Mophead flowers are large rounded flowerheads resembling pom-poms or, as the name suggests, the mind of your 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 bouquets of some viburnums and rhododendrons can show up, initially, just like those of some hydrangeas.Colors and land acidityIn most types the flowers are white, but in some species (notably H. macrophylla), can be blue, red, green, light purple, or dark purple. In these kinds the colour is affected by the existence of aluminium ions which can be found or tangled up depending upon the earth 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 result in pink or red flowers.

This is caused by a color change of the blossom pigments in the presence of aluminium ions which is often adopted into hyperaccumulating crops.[6] Bringing down 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 green a hydrangea is also affected 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 most other Hydrangea species is not damaged by aluminum and can't be changed or shifted. Hydrangeas also have a nickname called 'Change Rose'.
