A rose is a flowering shrub of the genus Rosa and the flower of this shrub. There are more than a hundred species of wild roses, all from the northern hemisphere and mostly from temperate regions. The species form a group of generally thorny shrubs or climbers, and sometimes trailing plants, reaching 2–5 m tall, rarely reaching as high as 20 m by climbing over other plants.
The leaves of most species are 5–15 cm long, pinnate, with (3–) 5–9 (–13) leaflets and basal stipules; the leaflets usually have a serrated margin, and often a few small thorns on the underside of the stem. The vast majority of roses are deciduous, but a few (particularly in southeast Asia) are evergreen or nearly so.
The flowers have five petals (with the exception of Rosa sericea which often has only four), usually white or pink, in a few species yellow or red. The ovary is inferior, developing below the petals and sepals.
Rosa canina hipsThe fruit of the rose is a berry-like structure called a rose hip. Rose species that produce open-faced flowers are attractive to pollinating bees and other insects, thus more apt to produce hips. Many of the domestic cultivars are so tightly petalled that they do not provide access for pollination. The hips of most species are red, but a few (e.g. Rosa pimpinellifolia) have dark purple to black hips. Each hip comprises an outer fleshy layer, and inside containing 5–25 seeds (technically achenes) embedded in a matrix of fine, but stiff, hairs. Rose hips of some species, especially the Dog Rose (Rosa canina) and Rugosa Rose (Rosa rugosa), are very rich in vitamin C, among the richest sources of any plant. The hips are eaten by fruit-eating birds such as thrushes and waxwings, which then disperse the seeds in their droppings. Some birds, particularly finches, also eat the seeds.
Most roses have thorns or prickles. The thorns are typically sickle-shaped hooks, which aid the rose in hanging onto other vegetation when growing over it. Some species such as Rosa rugosa and R. pimpinellifolia instead have densely packed straight spines, probably an adaptation to reduce browsing by animals, but also possibly an adaptation to trap wind-blown sand and so reduce erosion and protect their roots (both of these two species grow naturally on coastal sand dunes). Despite the presence of the thorns, roses are frequently browsed by deer. A few species of roses only have vestigial thorns that have no points.
Roses are subject to several diseases. The most serious is rose rust (Phragmidium mucronatum), a species of Rust fungus, which can defoliate the plant. More common, though less debilitating, are rose black spot, caused by the fungus Diplocarpon rosae, which makes circular black spots on the leaves in summer, and rose mildew, caused by Sphaerotheca pannosa. Roses are also used as food plants by the larvae of some Lepidoptera species; see list of Lepidoptera which feed on Roses.
The name originates from Persian *vrda, via Greek rhodon "rose" (Aeolic wrodon).

Some representative rose species
Roses are one of the most popular garden shrubs and are also among the most common flowers sold by florists. Roses are of great economic importance both as a crop for florists' use and for use in perfume.
Many thousands of rose hybrids and cultivars have been bred and selected for garden use, mostly double-flowered with many or all of the stamens mutated into additional petals. Twentieth-century rose breeders generally emphasized size and color, producing large, attractive blooms with little or no scent. Many wild and "old-fashioned" roses, by contrast, have a strong sweet scent. A few cultivars, such as the Lady Banks rose have been selected for having no thorns.
Roses thrive in in temperate climates, though certain species and cultivars can flourish in sub-tropical and even tropical climates, especially when grafted onto appropriate root-stock.
The fruit of the rose, called hips, are sometimes eaten, mainly for their vitamin C content. They are usually pressed and filtered to make rose-hip syrup, as the fine hairs surrounding the seeds are unpleasant to eat (resembling itching powder). They can also be used to make herbal tea, jam, jelly and marmalade.
There is no single system of classification for garden roses. In general, however, roses are placed in one of three main groups:
Roses are ancient symbols of love and beauty. The rose was sacred to a number of goddesses, and is often used as a symbol of the Virgin Mary. Roses are so important that the word means pink or red in a variety of languages (such as Romance languages, Greek, and Polish).
The rose is the national flower of England, as well as being the symbol of England's national rugby union team, and of the Rugby Football Union. It is also the provincial flower of Alberta (the wild rose), and the state flower of four US states: Iowa and North Dakota (R. arkansana), Georgia (R. laevigata), and New York (Rosa generally). Portland, Oregon counts "City of Roses" among its nicknames, and holds an annual Rose Festival.
A red rose (often held in a hand) is also a symbol of socialism or social democracy; it is also used as a symbol by the United Kingdom Labour Party, as well as by the French, Spanish (Spanish Socialist Workers' Party), Portuguese, Norwegian, Danish, Swedish, Finnish, Brazilian, Dutch (Partij van de Arbeid) and European socialist parties. This originates from the red rose used as a badge by the marchers in the May 1968 street protests in Paris.
The rose came to symbolize the Republic of Georgia's non-violent bid for freedom during its Rose Revolution.
Roses come in a variety of hues, each with a different symbolic meaning:
The Rose has various supernatural/literary attributes that are not discussed in this article.
The symbol of a rose can also refer to the red rose of Lancaster, and the white rose of York, from the Wars of the Roses period.
Roses are commonly portrayed by artists. The French artist Pierre-Joseph Redouté produced some of the most detailed paintings of roses.
Rose perfumes are made from attar of roses or rose oil, which is a mixture of volatile essential oils obtained by steam-distilling the crushed petals of roses. The technique originated in Persia (the word Rose itself is from Persian) then spread through Arabia and India, but nowadays about 70% to 80% of production is in the Rose Valley near Kazanluk in Bulgaria, with some production in Qamsar in Iran and Germany. The Kaaba in Mecca is annually washed by the Iranian rose water from Qamsar. In Bulgaria, Iran and Germany, damask roses (Rosa damascena 'Trigintipetala') are used. In the French rose oil industry Rosa centifolia is used. The oil, pale yellow or yellow-grey in color, is sometimes called 'Rose Absolute' oil to distinguish it from diluted versions. The weight of oil extracted is about one three-thousandth to one six-thousandth of the weight of the flowers - for example, about 2,000 flowers are required to produce one gramme of oil.
The main constituents of attar of roses are the fragrant alcohols geraniol, which has the empirical formula C10H18O and the structural formula CH3.C[CH3]:CH.CH2.CH2.C[CH3]:CH.CH2OH and l-citronellol; and rose camphor, an odourless paraffin.

The main constituents of attar of roses are the fragrant alcohols geraniol, which has the empirical formula C10H18O and the structural formula CH3.C[CH3]:CH.CH2.CH2.C[CH3]:CH.CH2OH and l-citronellol; and rose camphor, an odourless paraffin. Nokia is sometimes called aikon (Nokia backwards) by non-Nokia mobile phone users and by mobile software developers, because "aikon" is used in various SDK software packages, including Nokia's own Symbian Series 60 SDK. The weight of oil extracted is about one three-thousandth to one six-thousandth of the weight of the flowers - for example, about 2,000 flowers are required to produce one gramme of oil. The Nokia Tune was originally named "Gran Vals" on Nokia phones but was changed to "Nokia Tune" around 1998 when it became so well known that people referred to it as the Nokia Tune. The oil, pale yellow or yellow-grey in color, is sometimes called 'Rose Absolute' oil to distinguish it from diluted versions. The ringtone "Nokia Tune" (probably the world's most well-known ringtone) is actually based on a 19th-century guitar work named "Gran Vals" by Spanish musician Francisco Tárrega. In the French rose oil industry Rosa centifolia is used. Similarly, the "Ascending" SMS tone is Morse code for "Connecting People," Nokia's slogan. In Bulgaria, Iran and Germany, damask roses (Rosa damascena 'Trigintipetala') are used. The "Special" tone available to users of Nokia phones when receiving SMS (text messages) is actually Morse code for "SMS". The Kaaba in Mecca is annually washed by the Iranian rose water from Qamsar. Nokia Values are listed as: Customer Satisfaction, Respect, Achievement, and Renewal. The technique originated in Persia (the word Rose itself is from Persian) then spread through Arabia and India, but nowadays about 70% to 80% of production is in the Rose Valley near Kazanluk in Bulgaria, with some production in Qamsar in Iran and Germany. English is the official language spoken and written among Nokians regardless of location. Rose perfumes are made from attar of roses or rose oil, which is a mixture of volatile essential oils obtained by steam-distilling the crushed petals of roses. Nokia is a progressive and forward-thinking mobile technology group spending millions on research and development and priding itself on being "first to market" with new applications. The French artist Pierre-Joseph Redouté produced some of the most detailed paintings of roses. Equal opportunities and openness are also stressed, along with management leadership and employee participation. Roses are commonly portrayed by artists. Nokia's official corporate culture manifesto, The Nokia Way, emphasises speed and flexibility of decision making in a flat, networked organisation. The symbol of a rose can also refer to the red rose of Lancaster, and the white rose of York, from the Wars of the Roses period. Often, mispronunciation will lead to other words and meaning such as in a Nokia television commercial in which the name is mispronounced /nak:ia/ (double k), which means "(a bit of) wiener" in Finnish. The Rose has various supernatural/literary attributes that are not discussed in this article. In Spanish or French the spelling would be the same as in Finnish, while taking the correct stress pattern into account. Roses come in a variety of hues, each with a different symbolic meaning:. English approximation spelling cannot be used accurately, because the closest English vowels are not interchangeable with the Finnish ones. The rose came to symbolize the Republic of Georgia's non-violent bid for freedom during its Rose Revolution. Some English mispronunciations include [nəυ'ki:ə] "no-KEY-uh" and [nɒ'ki:ə] "knock-E-uh". This originates from the red rose used as a badge by the marchers in the May 1968 street protests in Paris. This creates problems for some, especially English speakers, who replace the vowels with schwas, as there are no direct equivalents to the Finnish short [o] or [a] sounds in English. A red rose (often held in a hand) is also a symbol of socialism or social democracy; it is also used as a symbol by the United Kingdom Labour Party, as well as by the French, Spanish (Spanish Socialist Workers' Party), Portuguese, Norwegian, Danish, Swedish, Finnish, Brazilian, Dutch (Partij van de Arbeid) and European socialist parties. The proper pronunciation of "Nokia" according to Finnish phonology is ['nokia], with stress on the first syllable, and all vowels in the name being short and unreduced — there are no schwas ("a" [ə] or "uh" [ɒ]). Portland, Oregon counts "City of Roses" among its nicknames, and holds an annual Rose Festival. Nokia has been engaged in a series of legal actions dealing with intellectual property issues. laevigata), and New York (Rosa generally). Nokia signed a contract with BenQ, a Taiwanese Original Design Manufacturer, to develop three high-end mobile phones, which are scheduled to retail by the end of 2005. arkansana), Georgia (R. Recently, Nokia joined other mobile phone manufacturers to embrace Taiwanese Original Design Manufacturers. It is also the provincial flower of Alberta (the wild rose), and the state flower of four US states: Iowa and North Dakota (R. This, however, diminished Nokia's public image in Finland, and produced a number of court cases along with, at least, one television show critical of Nokia [2]. The rose is the national flower of England, as well as being the symbol of England's national rugby union team, and of the Rugby Football Union. In 2004, Nokia resorted to similar streamlining practices with layoffs and organizational restructuring, although on a significantly smaller scale. Roses are so important that the word means pink or red in a variety of languages (such as Romance languages, Greek, and Polish). Nokia also began developing mobile phones for the NMT network; unfortunately, the company ran into serious financial problems in the 1990s and streamlined its manufacturing of mobile phones, mobile phone infrastructure, and other telecommunications areas, divesting itself of other items, such as televisions and personal computers. The rose was sacred to a number of goddesses, and is often used as a symbol of the Virgin Mary. (ICL), which later became part of Fujitsu; the personal computer operation was handed over to Fujitsu-Siemens AG. Roses are ancient symbols of love and beauty. In the 1980s, Nokia offered a series of personal computers called MikroMikko [1], however, these operations were sold to International Computers, Ltd. In general, however, roses are placed in one of three main groups:. In the 1970s Nokia became more involved in the telecommunications industry by developing the Nokia DX 200, a digital switch for telephone exchanges. There is no single system of classification for garden roses. The town and river are named after a small black marten found in the region. They can also be used to make herbal tea, jam, jelly and marmalade. The name Nokia originated from the river which flowed through the town of the same name (Nokia). They are usually pressed and filtered to make rose-hip syrup, as the fine hairs surrounding the seeds are unpleasant to eat (resembling itching powder). All three companies were merged as Nokia Corporation in 1967. The fruit of the rose, called hips, are sometimes eaten, mainly for their vitamin C content. At one time in history Nokia was a major manufacturer of boots for the military. Roses thrive in in temperate climates, though certain species and cultivars can flourish in sub-tropical and even tropical climates, especially when grafted onto appropriate root-stock. Shortly after World War I Finnish Rubber Works acquired Nokia wood mills as well as Finnish Cable Works, a producer of telephone and telegraph cables. A few cultivars, such as the Lady Banks rose have been selected for having no thorns. Finnish Rubber Works established its factories in the beginning of 20th century nearby and began using Nokia as its brand. Many wild and "old-fashioned" roses, by contrast, have a strong sweet scent. Nokia was established in 1865 as a wood-pulp mill by Finland-Swede Knut Fredrik Idestam on the banks of Nokia rapids. Twentieth-century rose breeders generally emphasized size and color, producing large, attractive blooms with little or no scent. . Many thousands of rose hybrids and cultivars have been bred and selected for garden use, mostly double-flowered with many or all of the stamens mutated into additional petals. Nokia provides mobile communication equipment for every major market and protocol, including GSM, CDMA, and WCDMA (UMTS). Roses are of great economic importance both as a crop for florists' use and for use in perfume. Nokia also produces mobile phone infrastructure and other telecommunications equipment for applications such as traditional voice telephony, ISDN, broadband access, professional mobile radio, voice over IP, wireless LAN, a line of digital terrestrial television receivers and satellite receivers. Roses are one of the most popular garden shrubs and are also among the most common flowers sold by florists. With headquarters in Keilaniemi of Espoo, Finland, Nokia is best known today for its leading range of mobile phones. Some representative rose species.

Light Pink: admiration, sympathy. Dark Pink: gratitude. Pink: grace. Red: love. These tend to give a more prominent display from a distance, so are more often used in large bedding schemes in public parks and similar spaces. Floribunda - Flowers often smaller, in large clusters of ten or more (often many more) on each stem. They are favoured in small gardens in formal situations, and for buttonhole roses. Hybrid Tea - The favourite florist's rose, with typically one to at most five or six large flowers per stem, the flower with numerous tightly arranged petals with reflexed tips (see photo, right). Many of the most popular modern cultivars can however be assigned to one of these two groups:
Those classes with both climbing and shrub forms are often grouped together. Miscellaneous - There are also a few smaller classes (such as Scots, Sweet Brier) and some climbing classes of old roses (including Ayrshire, Climbing China, Laevigata, Sempervirens, Noisette, Boursault, Climbing Tea, and Climbing Bourbon). Tradition dictates that they are named after the owner of the garden where they were rediscovered. They are "mystery roses" because their "proper" historical names have been lost. Most of these roses are likely Old Garden Rose cultivars that have otherwise dropped out of cultivation, or sports thereof. The roses have significant value and interest for those growing roses in tropical and semi-tropical regions, since they are highly resistant to both nematode damage and the fungal diseases that plague rose culture in hot, humid areas, and capable of blooming in hot and humid weather. Bermuda "Mystery" Roses - A group of several dozen "found" roses that have been grown in Bermuda for at least a century. Example: 'Lady Hillingdon'. gigantea in the ancestry of the Parks rose), teas are repeat-flowering roses although their fragrance is not always a tea scent. Somewhat more tender than other old garden roses (most likely because of R.

Four china roses ('Slater's Crimson China', 1792; 'Parsons' Pink China', 1793; 'Hume's Blush China', 1809; and 'Parks' Yellow Tea Scented China', 1824) were brought to Europe in the late eighteenth and nineteenth centuries which brought about the creation of the repeat flowering old garden roses and later the modern garden roses. China - The China roses brought with them an amazing ability to bloom repeatedly throughout the summer and into late autumn. Example: 'Comtesse de Murinais', 'Old Pink Moss'. Once-flowering. Moss - Closely related to the centifolias, these have a mossy excrescence on the stems and sepals. Examples: 'Centifolia', 'Paul Ricault'. Once-flowering. Centifolia (or Provence) - These roses, raised in the seventeenth century in the Netherlands, are named for their "one hundred" petals. Examples: 'Ispahan', 'Madame Hardy'. moschata) bloom later, in the autumn. Autumn Damasks (Gallicas crossed with R. phoenicea) bloom once in summer.
