Hydrangea (common names also Hydrangea, in English pronounced IPA [haɪˈdɹeɪnʤ(i)ə], and Hortensia) is a genus of about 70-75 species of flowering plants native to southern and eastern Asia (from Japan to China, the Himalaya and Indonesia) and North and South America. The flowers are extremely common in the Azores Islands of Portugal, particularly on Faial Island, which is known as the "blue island" due to the vast number of hydrangeas present on the island. By far the greatest species diversity is in eastern Asia, notably China and Japan (See: Japanese Ajisai flower). Most are shrubs 1-3 m tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous. Articles with similar titles include the NATO phonetic alphabet, which has also informally been called the “International Phonetic Alphabet”.

Hydrangea flowers are produced from early spring to late autumn; they grow in flowerheads (corymbs or panicles) at the ends of the stems. In many species, the flowerheads contain two types of flowers, small fertile flowers in the middle of the flowerhead, and large, sterile bract-like flowers in a ring around the edge of each flowerhead. Other species have all the flowers fertile and of the same size. Look up flower in Wiktionary, the free dictionary. ... This article does not cite any references or sources. ...

In most species the flowers are white, but in some species (notably H. macrophylla), can be blue, red, pink, or purple. In these species the exact colour often depends on the pH of the soil; acidic soils produce blue flowers, neutral soils produce very pale cream petals, and alkaline soils results in pink or purple. Hydrangeas are one of very few plants that accumulate aluminium. Aluminium is released from acidic soils, and in some species, forms complexes in the hydrangea flower giving them their blue colour.

Cultivation and uses

Hydrangeas are popular ornamental plants, grown for their large flowerheads, with Hydrangea macrophylla being by far the most widely grown with over 600 named cultivars, many selected to have only large sterile flowers in the flowerheads. Some are best pruned on an annual basis when the new leaf buds begin to appear. If not pruned regularly, the bush will become very 'leggy', growing upwards until the weight of the stems is greater than their strength, at which point the stems will sag down to the ground and possibly break. Other species only flower on 'old wood'. Thus new wood resulting from pruning will not produce flowers until the following season. Petunia This article does not cite any references or sources. ... Binomial name Hydrangea macrophylla (Thunb. ... This Osteospermum Pink Whirls is a successful cultivar. ...

Hydrangeas are moderately toxic if eaten, with all parts of the plant containing cyanogenic glycosides. However, poisoning is rare, as the plant does not look like an enticing food source. In chemistry, glycosides are certain molecules in which a sugar part is bound to some other part. ...

In Korea, Hydrangea serrata is used for a herbal tea called Sansugug (산수국). Herbal tea An herbal tea, tisane, or ptisan is an herbal infusion not made from the leaves of the tea bush (Camellia sinensis). ...
