A Rose for a Rose
Rose
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 prickly 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 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 flowers of most species roses have five petals with the exception of Rosa sericea which often has only four. Each petal is divided into two distinct lobes and are 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 aggregate 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, the hypanthium, which contains 5–160 "seeds" (technically dry single-seeded fruits called 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.
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 roots (both of these species grow naturally on coastal 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.
Roses are one of the most popular garden shrubs, as well as the most popular and commonly-sold 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 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. 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 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 climates, though certain species and cultivars can flourish in sub-tropical and even tropical climates, especially when grafted onto appropriate root-stock.

Roses thrive in temperate climates, though certain species and cultivars can flourish in sub-tropical and even tropical climates, especially when grafted onto appropriate root-stock.
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 European 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 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: 'Semi-plena', 'White Rose of York'.
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).
Damask - Robert de Brie is given credit for bringing them from 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', 'Madame Hardy'.
Centifolia (or Provence) - These roses, raised in the 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 stems and sepals 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).
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 counterpants. This made they 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 eighteenth and early 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 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, Phillipe Noisette, who in turn sent plants to his brother Louis in 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).
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 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'.
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 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', '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'.
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 parks 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 [1]. 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'.
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 conceptualized and created in the 1960s by David Austin of Shropshire, England, who wanted to rekindle interest in Old Garden Roses by hybridizing OGRs 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 winter-hardiness 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.
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 European 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.

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', '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'.
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 parks 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 [1]. 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'.
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 conceptualized and created in the 1960s by David Austin of Shropshire, England, who wanted to rekindle interest in Old Garden Roses by hybridizing OGRs 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 winter-hardiness 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.
According to the Victorian "language of flowers", different colored roses each have their own symbolic meaning:
Red: love
Pink: grace, gentle feelings of love
Dark Pink: gratitude
Light Pink: admiration, sympathy
White: innocence, purity, secrecy, friendship, reverence and humility.
Yellow: Yellow roses generally mean dying love or platonic love. In German-speaking countries, however, they can mean jealousy and infidelity.
Yellow with red tips: Friendship, falling in love
Orange: passion
Burgundy: beauty
Blue: mystery
Red: love
Pink: grace, gentle feelings of love
Dark Pink: gratitude
Light Pink: admiration, sympathy
White: innocence, purity, secrecy, friendship, reverence and humility.
Yellow: Yellow roses generally mean dying love or platonic love. In German-speaking countries, however, they can mean jealousy and infidelity.
Yellow with red tips: Friendship, falling in love
Orange: passion
Burgundy: beauty
Blue: mystery
Green: calm
Black: slavish devotion (as a true black rose is impossible to produce)
Purple: protection (paternal/maternal love)
Black: slavish devotion (as a true black rose is impossible to produce)
Purple: protection (paternal/maternal love)
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 gram 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.
No wonder then why material Roses prefer a Rose.
The "true sparrows", the Old World sparrows in the family Passeridae, are small passerine birds. The differences between sparrow species can be subtle. In general, sparrows tend to be small plump brownish or greyish birds with short tails and stubby powerful beaks. They are primarily seed-eaters, though they also consume small insects. A few species scavenge for food around cities and, like gulls or pigeons, will happily eat virtually anything in small quantities.
The Old World true sparrows are found indigenously in Europe, Africa and Asia. In Australia and the Americas, early settlers imported some species which quickly naturalised, particularly in urban and degraded areas. House Sparrows, for example, are now found throughout North America, in every state of Australia except Western Australia, and over much of heavily populated parts of South America.

The House Sparrow (Passer domesticus) is a member of the Old World sparrow family Passeridae. It occurs naturally in most of Europe and much of Asia. It has also followed humans all over the world and has been intentionally or accidentally introduced to most of the Americas, sub-Saharan Africa and Australia as well as urban areas in other parts of the world.
In the United States it is also known as the English Sparrow, to distinguish it from native species, as the large North American population is descended from birds deliberately imported from Britain in the late 19th century. They were introduced independently in a number of American cities in the years between 1850 and 1875 as a means of pest control.
Wherever people build, House Sparrows sooner or later come to share their abodes. Though described as tame and semi-domestic, neither is strictly true; humans provide food and home, not companionship. The House Sparrow remains wary of man.
This 14 to 16 centimetre long bird is abundant in temperate climates, but not universally common; in many hilly districts it is scarce. In cities, towns and villages, even around isolated farms, it can be the most abundant bird.
The male House Sparrow has a grey crown, cheeks and underparts, black on the throat, upper breast and between the bill and eyes. The bill in summer is blue-black, and the legs are brown. In winter the plumage is dulled by pale edgings, and the bill is yellowish brown. The female has no black on head or throat, nor a grey crown; her upperparts are streaked with brown. The juveniles are deeper brown, and the white is replaced by buff; the beak is dull yellow. The House Sparrow is often confused with the smaller and slimmer Tree Sparrow, which, however, has a chestnut and not grey crown, two distinct wing bars, and a black patch on each cheek.
The House Sparrow is gregarious at all seasons in its nesting colonies, when feeding and in communal roosts.
Although the Sparrows' young are fed on the larvae of insects, often destructive species, this species eats seeds, including grain where it is available.
In spring, flowers — especially those with yellow colours — are often eaten; crocuses, primroses and aconites seem to attract the house sparrow most. The bird will also hunt butterflies.
The Sparrow's most common call is a short and incessant chirp. It also has a double call note phillip which originated the now obsolete name of "phillip sparrow". While the young are in their nests, the older birds utter a long churr. At least three broods are reared in the season.
