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.
HYDRANGEA - Thank You for Understanding.
Have a wonderful day and thank you for your comments with all my heart, M, (*_*)

Well, long time no see.
I know my personality well enough to know that there are times when I don't post any pictures at all.
These past days the only thing in my mind was an exhibition held by the Czech Origami Society in a small town named Vítkov(about 6,000 inhabitants) which is pretty unimportant but since this is the first time my works are publicly displayed.... moreover I am one of three people who prepared this exhibition and it is more likely an exhibition of the three of us then of the Czech Origami Society. I was almost literally folding day and night and in the end I didn't take photos of the models I had folded which is now driving me crazy that the next time I will see my work again is in another two weeks.
Anyway, my walls and shelves got empty so I started folding the next day.
I used a bit more transparent paper which came in handy because the observer is delighted by the backlight effect. This way no one sees how poorly folded it is :D
Finally, of course I am not so clever to come up with such a beautiful pattern by myself so I got my inspiration here at flickr of Dáša Ševerová.
Hydrangea Colors Are Determined By The Acidity Of The Soil
Hydrangea flower color changes based on the pH in soil. As the graph depicts, soil with a pH of 5.5 or lower will produce blue flowers, a pH of 6.5 or higher will produce pink hydrangeas, and soil in between 5.5 and 6.5 will have purple hydrangeas.

The flowers on a hydrangea shrub can change from blue to pink or from pink to blue from one season to the next depending on the acidity level of the soil.[33] Adding organic materials such as coffee grounds and citrus peel will increase acidity and turn hydrangea flowers blue.[34]
White hydrangeas cannot be color-manipulated by soil pH because they do not produce pigment for color. In other words, while the hue of the inflorescence is variable dependent upon cultural factors, the color saturation is genetically predetermined.
In most species, the flowers are white. In some, however, (notably H. macrophylla), they can be blue, red, or purple, with color saturation levels ranging from the palest of pinks, lavenders & powder blues, to deep, rich purples, reds, and royal blues. In these species, floral color change occurs due to the availability of aluminium ions, a variable which itself depends upon the soil pH.[16][17] For H. macrophylla and H. serrata cultivars, the flower color can be determined by the relative acidity of the soil: an acidic soil (pH below 7), will have available aluminium ions and typically produce flowers that are blue to purple,[18] whereas an alkaline soil (pH above 7) will tie up aluminium ions and result in pink or red flowers. 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.[19]
Hydrangeas are A a genus of flowering plants.
Several terms redirect here. For other uses, see Hydrangea (disambiguation) and Hortensia (disambiguation).
Hydrangea (/haɪˈdreɪndʒə/[3][4] or /haɪˈdreɪndʒiə/[5]) is a genus of more than 70 species of flowering plants native to Asia and the Americas. Hydrangea is also used as the common name for the genus; some (particularly H. macrophylla) are also often called hortensia.[6] The genus was first described from Virginia in North America,[7] but by far the greatest species diversity is in eastern Asia, notably China, Korea, and Japan. Most are shrubs 1–3 m (3 ft 3 in – 9 ft 10 in) tall, but some are small trees, and others lianas reaching up to 30 m (100 ft) by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.[8]
Quick Facts Scientific classification, Type species ...
The flowers of many hydrangeas act as natural pH indicators, producing blue flowers when the soil is acidic and pink ones when the soil is alkaline.[9]
Etymology
Hydrangea is derived from Greek and means 'water vessel' (from ὕδωρ húdōr "water" + ἄγγος ángos or ἀγγεῖον angeîon "vessel"),[10][11][12] in reference to the shape of its seed capsules.[13] The earlier name, Hortensia, is a Latinised version of the French given name Hortense, honoring the French astronomer and mathematician Nicole-Reine Hortense Lepaute.[14] Philibert Commerson attempted to name the flower Lepautia or Peautia after Lepaute. However, the flower's accepted name later became Hortensia. This led to people believing Lepaute's name was Hortense, but the Larousse remarks that this is erroneous, and that the name probably came from hortus, garden.[15]
Life cycle
Hydrangea flowers are produced from early spring to late autumn; they grow in flowerheads (corymbs or panicles) most often at the ends of the stems. Typically the flowerheads contain two types of flowers: small non-showy fertile flowers in the center or interior of the flowerhead, and large, sterile showy flowers with large colorful sepals (tepals). These showy flowers are often extended in a ring, or to the exterior of the small flowers. Plants in wild populations typically have few to none of the showy flowers, while cultivated hydrangeas have been bred and selected to have more of the larger type flowers.
There are two flower arrangements in hydrangeas with corymb style inflorescences, which includes the commonly grown "bigleaf hydrangea"—Hydrangea macrophylla. 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, small flowers surrounded by outer rings of larger flowers having showy sepals or tepals. The flowers of some rhododendrons and viburnums can appear, at first glance, similar to those of some hydrangeas.
Colors and soil acidity
Hydrangea flower color changes based on the pH in soil. As the graph depicts, soil with a pH of 5.5 or lower will produce blue flowers, a pH of 6.5 or higher will produce pink hydrangeas, and soil in between 5.5 and 6.5 will have purple hydrangeas.

Fossil record
Hydrangea knowltoni
†Hydrangea alaskana is a fossil species recovered from Paleogene strata at Jaw Mountain Alaska.[21] †Hydrangea knowltoni has been described from leaves and flowers recovered from the Miocene Langhian Latah Formation of the inland Pacific Northwest United states. The related Miocene species †Hydrangea bendirei is known to from the Mascall Formation in Oregon, and †Hydrangea reticulata is documented from the Weaverville Formation in California.[22][23]
Four fossil seeds of †Hydrangea polonica have been extracted from borehole samples of the Middle Miocene fresh water deposits in Nowy Sacz Basin, West Carpathians, Poland.[24]
Cultivation and uses
Hydrangeas are popular ornamental plants, grown for their large flowerheads, with Hydrangea macrophylla being by far the most widely grown. It has over 600 named cultivars, many selected to have only large sterile flowers in the flowerheads. Hydrangea macrophylla, also known as bigleaf hydrangea, can be broken up into two main categories; mophead hydrangea and lacecap hydrangea. 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.
The following cultivars and species have gained the Royal Horticultural Society's Award of Garden Merit under the synonym Schizophragma:[25]
S. hydrangeoides var. concolor 'Moonlight'[26]
S. hydrangeoides var. hydrangeoides 'Roseum'[27]
S. integrifolium[28]
Hydrangea root and rhizome are indicated for the treatment of conditions of the urinary tract in the Physicians' Desk Reference for Herbal Medicine and may have diuretic properties.[29] Hydrangeas are moderately toxic if eaten, with all parts of the plant containing cyanogenic glycosides.[30] Hydrangea paniculata is reportedly sometimes smoked as an intoxicant, despite the danger of illness and/or death due to the cyanide.[31][32]
The flowers on a hydrangea shrub can change from blue to pink or from pink to blue from one season to the next depending on the acidity level of the soil.[33] Adding organic materials such as coffee grounds and citrus peel will increase acidity and turn hydrangea flowers blue.[34]
A popular pink hydrangea called Vanilla Strawberry has been named "Top Plant" by the American Nursery and Landscape Association.
A hybrid "Runaway Bride Snow White", from Japan, won Plant of the Year at the 2018 RHS Chelsea Flower Show.[35]
In culture
In Japan, ama-cha (甘茶), 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. During the ceremony, ama-cha is poured over a statue of Buddha 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 an herbal tea called sugukcha (수국차) or isulcha (이슬차).
The pink hydrangea has risen in popularity all over the world, especially in Asia. The given meaning of pink hydrangeas is popularly tied to the phrase "you are the beat of my heart," as described by the celebrated Korean florist Tan Jun Yong, who 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!"[36]
Hydrangea quercifolia was declared the official state wildflower of the U.S. state of Alabama in 1999.[37]
Hydrangeas were used by the Cherokee people of what is now the Southern U.S. as a mild diuretic and cathartic; it was considered a valuable remedy for stone and gravel in the bladder.[38]
Extrafloral nectaries were reported on hydrangea species by Zimmerman 1932, but Elias 1983 regards this as "doubtful".[39]
To our surprise our hydrangea has been going wild with abundant and huge blooms even if the calendar says it's getting to be time to rest.

Dried hydrangea blossoms left over from last summer. Not exactly a sign of spring, but it's what I found when I went out looking for some flowers to photograph. :-)
The Challenge Factory Winner - Category: Brown - February 27, 2014.
The hydrangea in our front yard seems to show at its prettiest in the low-angle early morning light. I stepped out five minutes later to see if I could improve on this shot but it was already in complete shade.
The hydrangeas in our front garden, Lj's favorite, are producing a ton of blooms.
Applied raw linen, apple blush and necropolis textures from Flypaper, lightly masked from flower and jar- although new to textures and their application, it's really a lot of fun playing around with them and I very much like the painterly effect you can achieve for certain images.
