A '''rose''' is a perennial flowering [[shrub]] or vine of the [[genus]] '''''Rosa''''', within the family [[rosaceae]], that contains over 100 species. The species form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp [[thorns]]. Most are native to Asia, with smaller numbers of species native to Europe, North America, and northwest Africa. Natives, [[cultivar]]s and [[hybrid]]s are all widely grown for their beauty and fragrance. [http://www.britannica.com/EBchecked/topic/509710/rose]
The leaves are alternate and [[pinnate|pinnately compound]], with sharply toothed oval shaped leaflets. The plants fleshy edible fruit is called a [[rose hip]]. Plants range in size from tiny miniature roses to climbers that can reach 20 metres. Species from different parts of the world easily hybridize, giving rise to the many types of garden roses.
The name originates from [[Latin]] ''rosa'', borrowed through [[Oscan language|Oscan]] from [[Magna Graecia|colonial Greek]] in southern [[Italy]]: ''rhodon'' ([[Aeolic]] form: ''wrodon''), from [[Aramaic]] ''wurrdā'', from [[Assyrian language|Assyrian]] ''wurtinnu'', from Old Iranian *''warda'' (cf. [[Armenian language|Armenian]] ''vard'', [[Avestan]] ''warda'', [[Sogdian language|Sogdian]] ''ward'', [[Parthian language|Parthian]] ''wâr'').[http://www.rose-bushes.com/about/][http://www.iranica.com/articles/v11f1/v11f1033.html]
[[Attar of rose]] is the steam-extracted essential oil from rose flowers that has been used in perfumes for centuries. [[Rose water]], made from the rose oil, is widely used in Asian and Middle Eastern cuisine. Rose hips are sometimes made into [[jam]], [[Jelly (fruit preserves)|jelly]] and [[marmalade]] or brewed for tea, mainly for their vitamin C content. They are also pressed and filtered to make rose hip syrup. Rose hips are also used to produce an [[Rose hip seed oil|oil]] used in skin products.
==Botany==
[[Image:Rosa canina hips.jpg|thumb|upright|''[[Rosa canina]]'' hips]]
The [[leaf|leaves]] of most species are 5–15 centimetres long, [[pinnate]], with (3–) 5–9 (–13) leaflets and basal stipules; the leaflets usually have a serrated margin, and often a few small prickles 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 [[flower]]s of most species roses have five petals, with the exception of ''[[Rosa sericea]]'', which usually has only four. Each petal is divided into two distinct lobes and is usually white or pink, though in a few species yellow or red. Beneath the petals are five sepals (or in the case of some [[Rosa sericea]], four). These may be long enough to be visible when viewed from above and appear as green points alternating with the rounded petals. The ovary is inferior, developing below the petals and sepals.
The [[Fruit#Aggregate fruit|aggregate fruit]] of the rose is a berry-like structure called a [[rose hip]]. Rose species that produce open-faced flowers are attractive to [[pollination|pollinating]] [[bee]]s and other [[insect]]s, 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, the [[hypanthium]], which contains 5–160 "seeds" (technically dry single-seeded fruits called [[achene]]s) 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 [[bird]]s such as [[Thrush (bird)|thrushes]] and [[waxwing]]s, which then disperse the seeds in their droppings. Some birds, particularly [[finch]]es, also eat the seeds.
While the sharp objects along a rose stem are commonly called "thorns", they are actually prickles — outgrowths of the epidermis (the outer layer of tissue of the stem). True thorns, as produced by e.g. ''[[Citrus]]'' or ''[[Pyracantha]]'', are modified stems, which always originate at a node and which have nodes and internodes along the length of the thorn itself. Rose prickles 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'' 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 [[root]]s (both of these species grow naturally on [[coast]]al [[dune|sand dunes]]). Despite the presence of prickles, roses are frequently browsed by [[deer]]. A few species of roses only have vestigial prickles that have no points.

==Pests and diseases==
{{Main|Pests and diseases of roses|List of rose diseases}}
Roses are subject to several [[disease]]s. The most '''serious''' is [[rose rust]] (''Phragmidium mucronatum''), a species of [[rust (fungus)|rust fungus]], which can defoliate the plant. More common, though less debilitating, are [[Black Spot (disease)|rose black spot]], caused by the fungus ''Diplocarpon rosae'', which makes circular black spots on the leaves in summer, and [[powdery mildew]], caused by ''Sphaerotheca pannosa''. Fungal diseases are best solved by a preventative [[Fungicide|fungicidal]] spray program rather than by trying to cure an infection after it is visible. After the disease is visible, its spread can be minimized through pruning and use of fungicides although actual infection cannot be reversed. Some rose varieties are considerably less susceptible than others to fungal disease.
The main insect pest affecting roses is the [[aphid]] (greenfly), which sucks the sap and weakens the plant. [[Coccinellidae|Ladybird]]s are a predator of aphids and should be encouraged in the rose garden. Spraying with insecticide is often recommended but should be done with care to minimize loss of beneficial insects. Roses are also used as food plants by the [[larva]]e of some [[Lepidoptera]] ([[butterfly]] and [[moth]]) species; see [[list of Lepidoptera that feed on roses]].

{{seealso|Rose cultivars named after celebrities}}
Roses are one of the most popular [[garden]] shrubs, as well as the most popular and commonly sold [[florist|florists']] flowers. In addition to their great economic importance as a florists crop, roses are also of great value to the [[perfume]] industry.
Many thousands of rose [[Hybrid (biology)|hybrids]] and [[cultivar]]s have been bred and selected for garden use, mostly [[double-flowered]] with many or all of the [[stamen]]s mutated into additional [[petal]]s. As long ago as 1840 a collection numbering over one thousand different cultivars, varieties and species was possible when a rosarium was planted by [[Loddiges|Loddiges nursery]] for [[Abney Park Cemetery]], an early Victorian garden cemetery and arboretum in England. 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.
Roses thrive in [[temperate climate]]s, though certain species and cultivars can flourish in [[sub-tropical]] and even [[tropical]] climates, especially when [[grafting|grafted]] onto appropriate [[rootstock]].
There is no single system of classification for garden roses. In general, however, roses are placed in one of three main groups:
*'''Wild Roses''' — The wild roses includes the species listed above and some of their hybrids.
*'''Old Garden Roses''' — Most Old Garden Roses are classified into one of the following groups. In general, Old Garden Roses of [[Europe]]an or [[Mediterranean]] origin are once-blooming shrubs, with notably fragrant, double-flowered blooms primarily in shades of white, pink and red. The shrubs' foliage tends to be highly disease-resistant, and they generally bloom only on two-year-old canes.
**'''Alba''' — Literally "white roses", derived from ''R. arvensis'' and the closely allied ''R. alba''. These are some of the oldest garden roses, probably brought to [[Great Britain]] by the [[Ancient Rome|Romans]]. The shrubs flower once yearly in the spring with blossoms of white or pale pink. The shrubs frequently feature gray-green foliage and a climbing habit of growth . Examples: 'Alba Semiplena', '[[White Rose of York]]'.
**'''[[Gallic Rose|Gallica]]''' — The gallica roses have been developed from ''R. gallica'', which is a native of central and southern [[Europe]]. They flower once in the summer over low shrubs rarely over 4' tall. Unlike most other once-blooming Old Garden Roses, the gallica class includes shades of red, maroon and deep purplish crimson. Examples: 'Cardinal de Richelieu', 'Charles de Mills', 'Rosa Mundi' (''R. gallica versicolor'').
**'''[[Rosa damascena|Damask]]''' — Robert de Brie is given credit for bringing them from [[Iran|Persia]] to Europe sometime between 1254 and 1276, although there is evidence from ancient Roman frescoes that at least one damask rose, the Autumn Damask, existed in Europe for hundreds of years prior. Summer damasks (crosses between gallica roses and ''R. phoenicea'') bloom once in summer. Autumn damasks (Gallicas crossed with ''R. moschata'') bloom again later, in the autumn. Shrubs tend to have rangy to sprawly growth habits and vicious thorns. The flowers typically have a more loose petal formation than gallicas, as well as a stronger, tangy fragrance. Examples: '[[Ispahan (rose)|Ispahan]]', 'Madame Hardy'.
**'''[[Rosa centifolia|Centifolia]] (or Provence)''' — These roses, raised in the [[17th Century|seventeenth century]] in the [[Netherlands]], are named for their "one hundred" petals; they are often called "cabbage" roses due to the globular shape of the flowers. The result of damask roses crossed with albas, the centifolias are all once-flowering. As a class, they are notable for their inclination to produce mutations of various sizes and forms, including moss roses and some of the first miniature roses (see below) . Examples: 'Centifolia', 'Paul Ricault'.
**'''Moss''' — Mutations of primarily centifolia roses (or sometimes damasks), these have a mossy excrescence on the [[Plant stem|stems]] and [[sepal]]s that often emits a pleasant woodsy or balsam scent when rubbed. Moss roses are cherised for this unique trait, but as a group they have contributed nothing to the development of new rose classifications. Moss roses with centifolia background are once-flowering; some moss roses exhibit repeat-blooming, indicative of Autumn Damask parentage. Example: 'Common Moss' (centifolia-moss), 'Alfred de Dalmas' (Autumn Damask moss).
**'''[[Rosa chinensis|China]]''' — The China roses were grown in East Asia for thousands of years and finally reached Western Europe in the late 1700s. Compared to the aforementioned European rose classes, the China roses had smaller, less fragrant, more poorly formed blooms carried over twiggier, more cold-sensitive shrubs. Yet they possessed the amazing ability to bloom repeatedly throughout the summer and into late autumn, unlike their European counterparts. This made them highly desirable for hybridization purposes in the early 1800s. The flowers of China roses were also notable for their tendency to "suntan," or darken over time — unlike the blooms of European roses, which tended to fade after opening. 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 [[18th Century|eighteenth]] and early [[19th Century|nineteenth centuries]]. This brought about the creation of the first classes of repeat-flowering Old Garden Roses, and later the Modern Garden Roses. Examples: 'Old Blush China', 'Mutabilis'.
**'''Portland''' — The Portland roses represent the first group of crosses between China roses and European roses, specifically gallicas and damasks. They were named after the [[Duke of Portland|Duchess of Portland]] who received (from [[Italy]] in 1800) a rose then known as ''R. paestana'' or 'Scarlet Four Seasons' Rose' (now known simply as 'The Portland Rose'). The whole class of Portland roses was thence developed from that one rose. The first repeat-flowering class of rose with fancy European-style blossoms, they are mostly descended from hybrids between damask and China roses. The plants tend to be fairly short and shrubby, with proportionately short flower stalks. Example: 'James Veitch', 'Rose de Rescht', 'Comte de Chambourd'.
**'''Bourbon''' — Bourbons originated on l'Île de Bourbon (now called [[Réunion]]) off the coast of Madagascar in the Indian Ocean. They are most likely the result of a cross between the Autumn Damask and the 'Old Blush' China rose, both of which were frequently used as hedging materials on the island. They flower repeatedly over vigorous, frequently semi-climbing shrubs with glossy foliage and purple-tinted canes. They were first Introduced in [[France]] in 1823. Examples: 'Louise Odier', 'Mme. Pierre Oger', 'Zéphirine Drouhin'.
**'''Noisette''' — The first Noisette rose was raised as a hybrid seedling by a South Carolina rice planter named John Champneys. Its parents were the China Rose 'Parson's Pink' and the autumn-flowering musk rose (''Rosa moschata''), resulting in a vigorous climbing rose producing huge clusters of small pink flowers from spring to fall. Champneys sent seedlings of his rose (called 'Champneys' Pink Cluster') to his gardening friend, Philippe Noisette, who in turn sent plants to his brother Louis in [[Paris, France|Paris]], who then introduced 'Blush Noisette' in 1817. The first Noisettes were small-blossomed, fairly winter-hardy climbers, but later infusions of Tea rose genes created a Tea-Noisette subclass with larger flowers, smaller clusters, and considerably reduced winter hardiness. Examples: 'Blush Noisette', 'Mme. Alfred Carriere' (Noisette), 'Marechal Niel' (Tea-Noisette). (See [[:fr:Rosier de Noisette|French]] and [[:de:Noisette-Rose|German]] articles on Noisette roses)
**'''Tea''' — The result of crossing two of the original China roses ('Hume's Blush China' and 'Parks' Yellow Tea Scented China') with various Bourbons and Noisette roses, tea roses are considerably more tender than other Old Garden Roses (due to cold-tender ''Rosa gigantea'' in the ancestry of the 'Parks' Yellow' rose). The teas are repeat-flowering roses, named for their fragrance being reminiscent of Chinese black tea (although this is not always the case). The color range includes pastel shades of white, pink and yellow, and the petals tend to roll back at the edges, producing a petal with a pointed tip. The individual flowers of many cultivars are semi-pendent and nodding, due to weak flower stalks. Examples: 'Lady Hillingdon', 'Maman Cochet'.
**'''Hybrid Perpetual''' — The dominant class of roses in [[Victorian Era|Victorian]] England, they first emerged in 1838 and were derived to a great extent from the Bourbons. They became the most popular garden and florist roses of northern Europe at the time, as the tender tea roses would not thrive in cold climates. The "perpetual" in the name hints at repeat-flowering, but many varieties of this class had poor reflowering habits; the tendency was for a massive spring bloom, followed by either scattered summer flowering, a smaller autumn burst, or sometimes nothing at all until next spring. Due to a limited color palette (white, pink, red) and lack of reliable repeat-bloom, the hybrid perpetuals were ultimately overshadowed by their own descendants, the Hybrid Teas. Examples: 'Ferdinand Pichard', 'Reine Des Violettes', 'Paul Neyron'.
**'''Hybrid Musk''' - This group was primarily developed by Rev. [[Joseph Pemberton]], a British rosarian, in the first decades of the 20th century, based upon 'Aglaia', a 1896 cross by Peter Lambert. A seedling of this rose, 'Trier', is considered to the be foundation of the class. The genetics of the class are somewhat obscure, as some of the parents are unknown. ''Rose multiflora'', however, is known to be one parent, and ''R. moschata'' (the musk rose) also figures in its heritage, though it is considered to be less important than the name would suggest. Hybrid musks are disease-resistant, remontant and generally cluster-flowered, with a strong, characteristic "musk" scent.<ref>{{cite web|url=http://www.rosegathering.com/hybridmusks.html|title=Hybrid Musks|author=Filiberti, Daphne}}</ref><ref>{{cite web|url=http://rdrop.com/~paul/musks/index.html|title=Hybrid Musks|author=Bardon, Paul}}</ref> Examples include 'Buff Beauty' and 'Penelope'.
**'''Bermuda "Mystery" Roses''' — A group of several dozen "found" roses that have been grown in [[Bermuda]] for at least a century. 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 [[black spot|fungal diseases]] that plague rose culture in hot, humid areas, and capable of blooming in hot and humid weather. Most of these roses are likely Old Garden Rose cultivars that have otherwise dropped out of cultivation, or sports thereof. They are "mystery roses" because their "proper" historical names have been lost. Tradition dictates that they are named after the owner of the garden where they were rediscovered.
**'''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, Boursault, Climbing Tea, and Climbing Bourbon). Those classes with both climbing and shrub forms are often grouped together.
*'''Modern Garden Roses''' — Classification of modern roses can be quite confusing because many modern roses have old garden roses in their ancestry and their form varies so much. The classifications tend to be by growth and flowering characteristics, such as "large-flowered shrub", "recurrent, large-flowered shrub", "cluster-flowered", "rambler recurrent", or "ground-cover non-recurrent". The following includes the most notable and popular classifications of Modern Garden Roses:
**'''[[Hybrid Tea]]''' — The favourite rose for much of the history of modern roses, hybrid teas were initially created by hybridizing Hybrid Perpetuals with Tea roses in the late 1800s. 'La France,' created in 1867, is universally acknowledged as the first indication of a new class of roses. Hybrid teas exhibit traits midway between both parents: hardier than the teas but less hardy than the hybrid perpetuals, and more everblooming than the hybrid perpetuals but less so than the teas. The flowers are well-formed with large, high-centered buds, and each flowering stem typically terminates in a single shapely bloom. The shrubs tend to be stiffly upright and sparsely foliaged, which today is often seen as a liability in the landscape. The hybrid tea class is important in being the first class of roses to include genes from the old Austrian brier rose (''Rosa foetida''). This resulted in an entirely new color range for roses: shades of deep yellow, apricot, copper, orange, true scarlet, yellow bicolors, lavender, gray, and even brown were now possible. The new color range did much to skyrocket hybrid tea popularity in the 20th century, but these colors came at a price: ''Rosa foetida'' also passed on a tendency toward disease-susceptibility, scentless blooms, and an intolerance of pruning, to its descendants. Hybrid teas became the single most popular class of garden rose of the 20th century; today, their reputation as being more high maintenance than many other rose classes has led to a decline in hybrid tea popularity among gardeners and landscapers in favor of lower-maintenance "landscape" roses. The hybrid tea remains the standard rose of the floral industry, however, and is still favoured in small gardens in formal situations. Examples: '[[Peace (rose)|Peace]]', 'Mr. Lincoln,' 'Double Delight.'
**'''[[Polyantha]]''' — Literally "many-flowered" roses, from the Greek "poly" (many) and "anthos" (flower). Originally derived from crosses between two East Asian species (''Rosa chinensis'' and ''R. multiflora''), polyanthas first appeared in France in the late 1800s alongside the hybrid teas. They featured short plants — some compact, others spreading in habit — with tiny blooms (1" in diameter on average) carried in large sprays, in the typical rose colors of white, pink and red. Their main claim to fame was their prolific bloom: From spring to fall, a healthy polyantha shrub might be literally covered in flowers, creating a strong color impact in the landscape. Polyantha roses are still regarded as low-maintenance, disease-resistant garden roses today, and remain popular for that reason. Examples: 'Cecile Brunner', 'The Fairy', 'Red Fairy'.
**'''[[Rosa Floribunda|Floribunda]]''' — Rose breeders quickly saw the value in crossing polyanthas with hybrid teas, to create roses with that bloomed with the polyantha profusion, but with hybrid tea floral beauty and color range. In 1909, the first polyantha/hybrid tea cross, 'Gruss an Aachen,' was created, with characteristics midway between both parent classes. As the larger, more shapely flowers and hybrid-tea-like growth habit separated these new roses from polyanthas and hybrid teas alike, a new class was created and named Floribunda, Latin for "many-flowering." Typical floribundas feature stiff shrubs, smaller and bushier than the average hybrid tea but less dense and sprawling than the average polyantha. The flowers are often smaller than hybrid teas but are carried in large sprays, giving a better floral effect in the garden. Floribundas are found in all hybrid tea colors and with the classic hybrid tea-shaped blossom, sometimes differing from hybrid teas only in their cluster-flowering habit. Today they are still used in large bedding schemes in public [[park]]s and similar spaces. Examples: 'Dainty Maid', 'Iceberg', 'Tuscan Sun'.
**'''[[Grandiflora]]''' — Grandifloras (Latin for "large-flowered") were the class of roses created in the mid 1900s to designate back-crosses between hybrid teas and floribundas that fit neither category — specifically, the 'Queen Elizabeth' rose, which was introduced in 1954<ref>[http://www.gardenmob.com/blog1/2006/07/13/the-great-roses-queen-elizabeth/ The Great Roses: Queen Elizabeth]</ref>. Grandiflora shrubs are typically larger than either hybrid teas or floribundas, and feature hybrid tea-style flowers borne in small clusters of three to five, similar to a floribunda. Grandifloras maintained some popularity from about the 1950s to the 1980s but today they are much less popular than either the hybrid teas or the floribundas. Examples: 'Queen Elizabeth', 'Comanche,' 'Montezuma'.
[[Image:"Meillandine" Rose in clay pot.jpg|thumb|upright|''Meillandine'' (a miniature rose) in a [[terra cotta]] flowerpot]]
**'''[[Miniature]]''' — All of the classes of Old Garden Roses — gallicas, centifolias, etc. — had corresponding miniature forms, although these were once-flowering just as their larger forms were. As with the standard-sized varieties, miniature Old Garden roses were crossed with repeat-blooming Asian species to produce everblooming miniature roses. Today, miniature roses are represented by twiggy, repeat-flowering shrubs ranging from 6" to 36" in height, with most falling in the 12"–24" height range. Blooms come in all the hybrid tea colors; many varieties also emulate the classic high-centered hybrid tea flower shape. Miniature roses are often marketed and sold by the floral industry as houseplants, but it is important to remember that these plants are largely descended from outdoor shrubs native to temperate regions; thus, most miniature rose varieties require an annual period of cold dormancy to survive. Examples: 'Petite de Hollande' (Miniature Centifolia, once-blooming), 'Cupcake' (Modern Miniature, repeat-blooming).
**'''[[Climbing/Rambling]]''' — As is the case with Miniature roses, all aforementioned classes of roses, both Old and Modern, have "climbing" forms, whereby the canes of the shrubs grow much longer and more flexible than the normal ("bush") forms. In the Old Garden Roses, this is often simply the natural growth habit of many cultivars and varieties; in many Modern roses, however, climbing roses are the results of spontaneous mutations. For example, 'Climbing Peace' is designated as a "Climbing Hybrid Tea," for it is genetically identical to the normal "shrub" form of the 'Peace' hybrid tea rose, except that its canes are long and flexible, i.e. "climbing." Most Climbing roses grow anywhere from 8'–20' in height and exhibit repeat-bloom. Rambler roses, although technically a separate class, are often lumped together with climbing roses. They also exhibit long, flexible canes, but are distinguished from true climbers in two ways: A larger overall size (20'–30' tall is common), and a once-blooming habit. It should be noted that both climbing roses and rambling roses are not true vines such as [[ivy]], [[clematis]] or [[wisteria]]; they lack the ability to cling to supports on their own, and must be manually trained and tied over structures such as arbors and pergolas. Examples: 'Blaze' (repeat-blooming climber), 'American Pillar' (once-blooming rambler).
**'''[[English/David Austin]]''' — Although not officially recognized as a separate class of roses by any established rose authority, English (aka David Austin) roses are often set aside as such by consumers and retailers alike. They were developed in the 1960s by [[David Austin]] of [[Shropshire]], [[England]], who wanted to rekindle interest in Old Garden Roses by hybridizing them with modern hybrid teas and floribundas. The idea was to create a new group of roses that featured blooms with old-fashioned shapes and fragrances, evocative of classic gallica, alba and damask roses, but with modern repeat-blooming characteristics and the larger modern color range as well. Austin mostly succeeded in his mission; his tribe of "English" roses, now numbering hundreds of varieties, has been warmly embraced by the gardening public and are widely available to consumers. It should be noted that the typical winterhardiness and disease-resistance of the classic Old Garden Roses has largely been compromised in the process; many English roses are susceptible to the same disease problems that plague modern hybrid teas and floribundas, and many are not hardy north of USDA Zone 5. Examples: 'Mary Rose,' 'Graham Thomas', 'Tamora'.
*'''Landscape Roses''' — These are a modern classifation of rose developed mainly for mass amenity planting. In the late 20th century, traditional hybrid tea and floribunda rose varieties fell out of favor amid gardeners and landscapers, as they are often labor- and chemical-intensive plants susceptible to myriad pest and disease problems. So-called "landscape" roses have thus been developed to fill the consumer desire for a garden rose that offers color, form and fragrance, but is also low maintenance and easy to care for. Most landscape roses having the following characteristics:
** Good disease resistance
** Lower growing habit, usually under 60cm
** Repeat flowering
** Disease and pest resistance
** Non suckering, growing on their own roots.
Principal parties involved in the breeding of new Landscape Roses varieties are Werner Noak (Germany) Meidiland Roses (France) Boot&Co. (Netherlands)
==Pruning==
Rose [[pruning]], sometimes regarded as a horticultural art form, is largely dependent on the type of rose to be pruned, the reason for pruning, and the time of year it is at the time of the desired pruning.
Most Old Garden Roses of strict European heritage (albas, damasks, gallicas, etc.) are shrubs that bloom once yearly, in late spring or early summer, on two-year-old (or older) canes. As such, their pruning requirements are quite minimal, and are overall similar to any other analogous shrub, such as [[lilac]] or [[forsythia]]. Generally, only old, spindly canes should be pruned away, to make room for new canes. One-year-old canes should never be pruned because doing so will remove next year's flower buds. The shrubs can also be pruned back lightly, immediately after the blooms fade, to reduce the overall height or width of the plant. In general, pruning requirements for OGRs are much less laborious and regimented than for Modern hybrids.
Modern hybrids, including the hybrid teas, floribundas, grandifloras, modern miniatures, and English roses, have a complex genetic background that almost always includes China roses (''R. chinensis''). China roses were evergrowing, everblooming roses from humid subtropical regions that bloomed constantly on any new vegetative growth produced during the growing season. Their modern hybrid descendants exhibit similar habits: Unlike Old Garden Roses, modern hybrids bloom continuously (until stopped by frost) on any new canes produced during the growing season. They therefore require pruning away of any spent flowering stem, in order to divert the plant's energy into producing new growth and thence new flowers.
Additionally, Modern Hybrids planted in cold-winter climates will almost universally require a "hard" annual pruning (reducing all canes to 8"–12" in height) in early spring. Again, because of their complex China rose background, Modern Hybrids are typically not as cold-hardy as European OGRs, and low winter temperatures often desiccate or kill exposed canes. In spring, if left unpruned, these damanged canes will often die back all the way to the shrub's root zone, resulting in a weakened, disfigured plant. The annual "hard" pruning of hybrid teas, floribundas, etc. should generally be done in early spring; most gardeners coincide this pruning with the blooming of forsythia shrubs. Canes should be cut about 1/2" above a vegetative bud (identifiable as a point on a cane where a leaf once grew).
For both Old Garden Roses and Modern Hybrids, any weak, damaged or diseased growth should be pruned away completely, regardless of the time of year. Any pruning of any rose should also be done so that the cut is made at a forty five degree angle above a vegetative bud. This helps the pruned stem callus over more quickly, and also mitigates moisture buildup over the cut, which can lead to disease problems.
For all general rose pruning (including cutting flowers for arrangements), sharp secateurs (hand-held, sickle-bladed pruners) should be used to cut any growth 1/2" or less in diameter. For canes of a thickness greater than 1/2", pole loppers or a small handsaw are generally more effective; secateurs may be damaged or broken in such instances.
===Deadheading===
[[Deadheading]] is the simple practice of manually removing any spent, faded, withered or discoloured flowers from rose shrubs over the course of the blooming season. The purpose of deadheading is to remove deteriorating parts of the plant so that the plant can focus its energy and resources on forming new offshoots and blooms. Roses are particularly responsive to deadheading.
Deadheading causes different effects on different varieties of roses. For continual blooming varieties, whether Old Garden roses or more modern hybrid varieties, deadheading allows the rose plant to continue forming new shoots, leaves, and blooms. For "once-blooming" varieties (that bloom only once each season), deadheading has the effect of causing the plant to form new green growth, even though new blooms will not form until the next blooming season.
For most rose gardeners, deadheading is used to refresh the growth of the rose plants to keep the rose plants strong, vibrant, and reproductive.
==History==
The rose has always been valued for its beauty and has a long history of symbolism. The ancient [[Greeks]] and [[Ancient Rome|Romans]] identified the rose with their goddesses of love referred to as Aphrodite and Venus. In [[Rome]] a wild rose would be placed on the door of a room where secret or confidential matters were discussed. The phrase ''[[sub rosa]]'', or "under the rose", means to keep a secret — derived from this ancient Roman practice.
Early [[Christian]]s identified the five petals of the rose with the five wounds of [[Christ]]. Despite this interpretation, their leaders were hesitant to adopt it because of its association with Roman excesses and pagan ritual. The red rose was eventually adopted as a symbol of the blood of the [[Christian]] martyrs. Roses also later came to be associated with the Virgin Mary.
Rose culture came into its own in [[Europe]] in the 1800s with the introduction of perpetual blooming roses from [[China]]. There are currently thousands of varieties of roses developed for bloom shape, size, fragrance and even for lack of prickles.

Roses are ancient symbols of [[love]] and [[beauty]]. The rose was sacred to a number of [[goddess]]es (including [[Isis]] and [[Aphrodite]]), and is often used as a symbol of [[the Virgin Mary]]. 'Rose' means pink or red in a variety of languages (such as [[Romance languages]], [[Greek language|Greek]], and [[Polish language|Polish]]).
The rose is the [[national flower]] of [[England]] and the United States<ref name="National Flower of the United States">{{Cite web|url=http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=browse_usc&docid=Cite:+36USC303|title=National Flower of the United States|accessdate=2008-02-04}}</ref>, as well as being the symbol of [[England Rugby]], and of the [[Rugby Football Union]]. It is also the provincial flower of [[Yorkshire]] and [[Lancashire]] in [[England]] (the white rose and red rose respectively) and of [[Alberta]] (the wild rose), and the state flower of four US states: [[Iowa]] and [[North Dakota]] ([[Rosa arkansana|''R. arkansana'']]), [[Georgia (U.S. state)|Georgia]] (''[[Rosa laevigata|R. laevigata]]''), and [[New York]]<ref name="State flower of New York">{{Cite web|url=http://www.netstate.com/states/symb/flowers/ny_rose.htm|title=New York State Flower|accessdate=2007-10-01}}</ref> (''[[Rosa]]'' generally). [[Portland, Oregon]] counts "City of Roses" among its nicknames, and holds an annual Rose Festival.
Roses are occasionally the basis of design for [[rose windows]], such windows comprising five or ten segments (the five petals and five sepals of a rose) or multiples thereof; however most Gothic rose windows are much more elaborate and were probably based originally on the wheel and other symbolism.
A red rose (often held in a hand) is a symbol of [[socialism]] or [[social democracy]]; it is also used as a symbol by the [[Labour Party (UK)|British]] and [[Irish Labour Party|Irish]] [[political party|Labour Parties]], as well as by the French, Spanish (Spanish Socialist Workers' Party), Portuguese, Norwegian, Danish, Swedish, Finnish, Brazilian, Dutch ([[Pvda|Partij van de Arbeid]]) and European socialist parties. This originated when the red rose was used as a badge by the marchers in the May 1968 street protests in [[Paris]]. [[White Rose]] was a World War II non violent resistance group in Germany.

Roses are often portrayed by [[artist]]s. The [[France|French]] artist [[Pierre-Joseph Redouté]] produced some of the most detailed paintings of roses.
[[Henri Fantin-Latour]] was also a prolific painter of still life, particularly flowers including roses. The Rose 'Fantin-Latour' was named after the artist.
Other impressionists including [[Claude Monet]] and [[Paul Cézanne]] have paintings of roses among their works.

==Perfume==
{{main|Rose oil}}
Rose perfumes are made from [[attar of roses]] or rose oil, which is a mixture of volatile [[essential oil]]s obtained by steam distilling the crushed petals of roses. The technique originated in [[Iran|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, Bulgaria|Rose Valley]] near [[Kazanluk]] in [[Bulgaria]], with some production in [[Qamsar]] in [[Iran]] and [[Germany]].{{Fact|date=July 2007}} 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 two thousand flowers are required to produce one gram of oil.
The main constituents of attar of roses are the fragrant [[alcohol]]s [[geraniol]] and l-[[citronellol]]; and rose camphor, an odourless [[paraffin]]. β-[[Damascenone]] is also a significant contributor to the scent.
