Rosa Gallica
''Rosa gallica'', the Gallic rose, French rose, or rose of Provins, is a species of flowering plant in the rose family, native to southern and central Europe eastwards to Turkey and the Caucasus. ''Rosa gallica'' was one of the first species of rose to be cultivated in central Europe. It is a parent of several important cultivars. Description ''Rosa gallica'' is a deciduous shrub forming large patches. The slender, straight prickles are various in size and frequency in this species. The leaves are pinnately-compound, with three to seven bluish-green leaflets. The flowers are clustered one to four together, on glandular pedicels. Each flower has five or more petals, sometimes producing double corollas. The flowers are fragrant and deep pink. The hips are globose to ovoid, 10–13 mm diameter, and orange to brownish. In the field of Food science, rose petal extract from ''Rosa gallica'' has been shown to have properties that reduce inflammation and wrinkling in human skin. ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflammation
Inflammation (from ) is part of the biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin ''calor'', ''dolor'', ''rubor'', ''tumor'', and ''functio laesa''). Inflammation is a generic response, and therefore is considered a mechanism of innate immunity, whereas adaptive immunity is specific to each pathogen. Inflammation is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and initiate tissue repair. Too little inflammation could lead to progressive tissue destruction by the harmful stimulus (e.g. bacteria) and compromise the survival of the organism. However inflammation can also have negative effects. Too much inflammation, in the form of chronic inflammation, is associated with variou ...

Flora Of Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles."

Roses
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through pinks, reds, oranges and yellows. Most species are native to Asia, with smaller numbers native to Europe, North America, and Northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' com ...

Blue Rose
A blue rose is a flower of the genus ''Rosa'' (family Rosaceae) that presents blue-to-violet pigmentation instead of the more common red, white, or yellow, through use of artificial means such as dyes. Blue roses are often used to symbolize mystery or the unattainable, since they do not exist in nature because of genetic limitations. In 2002, researchers used genetic modification to create roses that contain the naturally occurring (in other plants) blue pigment delphinidin. In 2004, this was then announced to the world. So-called "blue roses" have been bred by conventional hybridization methods, but the results, such as "Blue Moon", are more accurately described as lilac in color. Dyed roses Since blue roses do not exist in nature, as roses lack the specific gene that has the ability to produce a "true blue" color, blue roses are traditionally created by dyeing white roses. In a book entitled written by Andalusī agronomist Ibn al-'Awwām al-Ishbīlī in Arabic in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Engineering
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of Genetic engineering techniques, technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by Artificial gene synthesis, artificially synthesising the DNA. A Vector (molecular biology), construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the Lambda phage, lambda virus. As well as inserting genes, the process can be used to remove, or "Gene knockout, knock out", genes. The new DNA can either be inserted randomly or Gene targeting, targeted to a spe ...

Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Clare Matterson CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discov ...

Rosa × Damascena
''Rosa'' × ''damascena'' (Latin for damascene rose), more commonly known as the Damask rose, or sometimes as the Iranian Rose, Bulgarian rose, Taif rose & "Emirati rose", Ispahan rose, Castile rose, and Đulbešećerka (Bosnia and Herzegovina and the Balkans) is a rose hybrid, derived from '' Rosa gallica'' and '' Rosa moschata''. DNA analysis has shown that a third species, '' Rosa fedtschenkoana'', has made some genetic contributions to the Damask rose. The flowers are renowned for their fine fragrance, and are commercially harvested for rose oil (either "rose otto" or "rose absolute") used in perfumery and to make rose water and "rose concrete". The flower petals are also edible. They may be used to flavor food, as a garnish, as an herbal tea, and preserved in sugar as gulkand. It is the national flower of Iran. In 2019, Damascus rose was inscribed to the UNESCO Intangible Cultural Heritage Lists as an element of Syrian cultural heritage. Description The Damask rose is ...

County Flower
In 2002 Plantlife conducted a "County Flowers" public survey to assign flowers to each of the counties of the United Kingdom and the Isle of Man. The results of this campaign designated a single plant species to a "county or metropolitan area" in the UK and Isle of Man. Some English counties already had flowers traditionally associated with them before 2002, and which were different from those assigned to them by Plantlife, including the white rose for Yorkshire (assigned the harebell), the poppy for Norfolk (assigned the Alexanders), and the cowslip for Essex (assigned the poppy). Some flowers were assigned to multiple counties.

Red Rose Of Lancaster
The Red Rose of Lancaster (blazoned: ''a rose (heraldry), rose gules'') was the heraldic badge adopted by the royal House of Lancaster in the 14th century. In the modern era, it symbolises the county of Lancashire. The exact species or cultivar which it represents is thought to be ''Rosa gallica, Rosa gallica officinalis''. John of Gaunt's younger brother Edmund of Langley, 1st Duke of York (1341–1402), adopted the White rose of York as his heraldic badge. His descendants fought for control of the throne of England during several decades of civil warfare, which became known as the Wars of the Roses, after the heraldry of the House of York Adopted after the civil wars of the fifteenth century had ended, the red rose was the symbol of the English Monarchy. The opposition of the roses was a romantic invention created after the fact, and the Tudor arts under poets like Shakespeare gave the wars their popular conception: The Wars of the Roses, coined in the 19th century.
