Hydrangea L. è un genere di piante della famiglia delle Hydrangeaceae, originarie della Cina e del Giappone, comunemente note come ortensie.
Il genere comprende diverse specie di piante legnose arbustive originarie e molto diffuse nelle regioni orientali dell'Asia e dell'Himalaya.
La particolarità di questa pianta sono i fiori, riuniti in infiorescenze più o meno sferiche, dette corimbi o pannocchie, che portano fiori per lo più sterili, soprattutto quelli esterni, per cui sono sostituiti dai sepali, grandi e petaliformi, mentre le altre parti fiorali sono abortite.
La specie Hydrangea macrophilla comprende numerose varietà con grosse infiorescenze globose bianche, rosa, rosse o azzurre, utilizzate per la produzione in vaso o nei giardini.
Altre specie del genere Hydrangea sono l'H. paniculata, arbusto con ramificazioni sottili e decombenti sotto il peso delle piccole infiorescenze bianche, che viene coltivata a forma di alberetto o cespuglio e si moltiplica per talea e l'H. arborescens, arbusto con foglie decidue e fiori profumati.
Fu introdotta in Europa nel XVIII secolo dal naturalista Philibert Commerson.
La coltivazione in piena terra richiede clima fresco durante l'estate, esige terreno di brughiera con aggiunta di terriccio di foglie e sabbia, neutro o acido. L'acidità del terreno influenza il colore dei fiori: il blu indica un terreno più acido ( pH < 6 ). L'ortensia può essere coltivata in vaso, forzandola in serra per la fioritura primaverile.
L'esposizione da preferire è a mezz'ombra con irrigazioni generose e frequenti concimazioni liquide nella stagione calda.
La potatura viene effettuata prima della ripresa vegetativa accorciando drasticamente i rami vecchi e lasciando solo due gemme per ramo.
La moltiplicazione avviene per talea erbacea o legnosa nel periodo di ottobre.
Hydrangea (common names Hydrangea and Hortensia) is a genus of about 70 to 75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and North and South America. By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 metres by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.
Having been introduced to the Azores Islands of Portugal, they are now very common there, particularly on Faial Island, which is known as the "blue island" due to the vast number of hydrangeas present on the island, and on Flores Island. and Sao Miguel.
Species in the related genus Schizophragma, also in Hydrangeaceae, are also often known as hydrangeas. Schizophragma hydrangeoides and Hydrangea petiolaris are both commonly known as climbing hydrangeas.
There are two flower arrangements in hydrangeas. Mophead flowers are large round flowerheads resembling pom-poms or, as the name implies, the head of a mop. In contrast, lacecap flowers bear round, flat flowerheads with a center core of subdued, fertile flowers surrounded by outer rings of showy, sterile flowers.
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 sterile and of the same size.
Colors and acidityIn most species the flowers are white, but in some species (notably H. macrophylla), can be blue, red, pink, light purple, or dark purple. In these species the color is affected by 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. This is caused by a color change of the flower pigments in the presence of aluminium ions which can be taken up into hyperaccumulating plants.
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.
Hydrangeas are moderately toxic if eaten, with all parts of the plant containing cyanogenic glycosides.Hydrangea paniculata is reportedly sometimes smoked as an intoxicant, despite the danger of illness and/or death due to the cyanide.
In Japan, ama-cha, meaning sweet tea, is another herbal tea made from Hydrangea serrata, whose leaves contain a substance that develops a sweet taste (phyllodulcin). For the fullest taste, fresh leaves are crumpled, steamed, and dried, yielding dark brown tea leaves. Ama-cha is mainly used for kan-butsu-e (the Buddha bathing ceremony) on April 8 every year—the day thought to be Buddha's birthday in Japan. Ama-cha is poured over a statue of Buddha in the ceremony and served to people in attendance. A legend has it that on the day Buddha was born, nine dragons poured Amrita over him; ama-cha is substituted for Amrita in Japan.
In Korean tea, Hydrangea serrata is used for a herbal tea called sugukcha or ilsulcha .
The pink hydrangea has risen in popularity all over the world, namely Asia. Pink hydrangeas have many different meanings, but generally means, "You are the beat of my heart", as described by the celebrated Asian florist Tan Jun Yong, where he was quoted saying, "The light delicate blush of the petals reminds me of a beating heart, while the size could only match the heart of the sender!"
The Hydrangeas did very well this year, although in general the heads are smaller probably due to the hot summer.
Now some have been dried and form a lovely dash of colour in the room.
Hydrangea, the name, comes from the Greek words "hydro" or water, and "angeion," or vase = water vase, they prefer a lot of water.
A very ancient plant, found in fossils going back thousands of years.
Flower lovers will know that there is a flower language.
Every sentiment is expressed in one form or another by delicate blooms.
Of course, even the experts disagree on the "true meaning" of many flowers and most have different meanings to different people.
So, while all flowers convey thoughtfulness and love, a gift of flowers for a special someone will always create its own personal meaning, too.

I was teaching the Hydrangea to my girlfriend, and she took this photo while I was folding. This design have always been one of my favourite, is a pleasure to fold and even more to teach.
As you can know the hydrangea is one of my favorit flowers. Around our home we have them in pots and in the ground. From both you see some examples.
See the whole serie from today.
Have a very nice weekend.
