Rose in the context of "Rose species"

A cultivar is a kind of cultivated plant that people have selected for desired traits and which retains those traits when propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word cultivar was coined as a term meaning "cultivated variety".

Popular ornamental plants like roses, camellias, daffodils, rhododendrons, and azaleas are commonly cultivars produced by breeding and selection or as sports, for floral colour or size, plant form, or other desirable characteristics. Similarly, the world's agricultural food crops are almost exclusively cultivars that have been selected for characters such as improved yield, flavour, and resistance to disease. Since the advent of genetic engineering in the 1970s and the rise of its application in crop breeding in the 1980s, very few wild plants are used as commercial food sources. Trees used in forestry are also special selections grown for their enhanced quality and yield of timber, for example American timber company Weyerhaeuser is the leading grower of genetically modified Douglas-fir trees, one of the most commonly harvested trees.

Rosaceae (/roʊˈzeɪsiː.iː, -si.aɪ, -si.eɪ/), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera.

The name is derived from the type genus Rosa. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere.

Rose window is often used as a generic term applied to a circular window, but is especially used for those found in Gothic cathedrals and churches. The windows are divided into segments by stone mullions and tracery. The term rose window was not used before the 17th century and comes from the English flower name rose.

The name "wheel window" is often applied to a window divided by simple spokes radiating from a central boss or opening, while the term "rose window" is reserved for those windows, sometimes of a highly complex design, which can be seen to bear similarity to a multi-petalled rose. Rose windows are also called "Catherine windows" after Saint Catherine of Alexandria, who was sentenced to be executed on a spiked breaking wheel. A circular window without tracery such as are found in many Italian churches, is referred to as an ocular window or oculus.

Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the corolla. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the calyx and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term tepal is appropriate include genera such as Aloe and Tulipa. Conversely, genera such as Rosa and Phaseolus have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they include Liliales, an alternative name is lilioid monocots.

Although petals are usually the most conspicuous parts of animal-pollinated flowers, wind-pollinated species, such as the grasses, either have very small petals or lack them entirely (apetalous).

Cut flowers are flowers and flower buds (often with some stem and leaf) that have been cut from the plant bearing it. It is removed from the plant for decorative use. Cut greens are leaves with or without stems added to the cut flowers for contrast and design purposes.

Floral design professionals work at florist shops (floristry) and use their design skills and experience with many types of flowers and greens to create works of art with flowers.

Garden roses are predominantly hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars has been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging.

The cultivars are classified in a number of different and overlapping ways, generally without much reference to strict botanical principles. Taking overall size and shape, the most common type is the bush rose, a rounded plant from 2 foot up to about 7 foot tall, above which height roses generally fall into the "'climbing and rambling'" class, the latter spreading wider; support is needed for these. There are also miniature roses, generally small bushes, and low sprawling ground cover roses, both up to about 15 inches tall. Most modern roses are propagated by budding onto rootstocks much closer to wild species; in "standard" shapes there is a single bare stem, with the graft at the top of that. Shrub roses are a rather loose category that include some of the original species and cultivars closely related to them, plus cultivars that grow rather larger than most bush roses. Technically all roses are shrubs. In terms of ancestry, roses are often divided into three main groups: Wild, Old Garden, and Modern Garden roses, with many subdivisions of these.

Theodore Wirth (1863–1949) was instrumental in designing the Minneapolis system of parks. Swiss-born, he was widely regarded as the dean of the local parks movement in America. The various titles he was given included administrator of parks, horticulturalist, and park planner. Before emigrating to America in 1888, he worked as a florist and landscaper in Zurich, London, and Paris. He married Leonie Mense, the daughter of his employer in Glen Cove, Long Island, before taking a job as superintendent of parks in Hartford, Connecticut in 1896, where he developed the first municipal rose garden in the country.

In 1904 the city of Minneapolis offered him the position of Superintendent of Parks in that fast-growing Midwest city. Although he didn't act on it, his stated goal provided for a playground within a quarter-mile of every child and a complete recreation center within a half-mile of every family. During his 30-year tenure there, he managed the expansion the park system from 1,810 acres (7 km) to 5,241 acres (21 km), in a city of 37,387 acres (14%). Park land included parks, golf courses, flower gardens and boulevards. Unlike earlier park planners, he believed that parks ought to be used by the residents. His park development is enjoyed daily by residents and visitors on the Grand Rounds Scenic Byway, at Minnehaha Falls, along the 12-mile (19 km) path following Minnehaha Creek, at Lake Harriet, Bde Maka Ska, Lyndale Park, Winchell Trail, and scores of other public open spaces in Minneapolis. The lakes, parks, and outdoor recreation areas that Minneapolis features are often cited by users as some of the most important factors in their quality of life.

Keukenhof (Dutch pronunciation: [ˈkøːkə(n)ˌɦɔf]; lit. 'Kitchen garden'), also known as the Garden of Europe, is one of the world's largest flower gardens, situated in the municipality of Lisse, in the Netherlands. According to the official website, Keukenhof Park covers an area of 32 hectares (79 acres) and approximately 7 million flower bulbs are planted in the gardens annually. While it is widely known for its tulips, Keukenhof also features numerous other flowers, including hyacinths, daffodils, lilies, roses, carnations and irises.

Keukenhof is located in the province of South Holland, south of Haarlem and southwest of Amsterdam in the area called the "Dune and Bulb Region" (Duin- en Bollenstreek). It is accessible by bus from Haarlem and Leiden train stations as well as Schiphol. Though its grounds are open year-round for private affairs and festivals, Keukenhof is only open to the general public for a world-renowned eight week tulip display from mid-March to mid-May, with peak viewing arriving near mid-April, depending on growing season weather, which varies annually. In 2019, 1.5 million people visited Keukenhof, equivalent to 26,000 visitors per day. By comparison, the Rijksmuseum receives an average of 8,000 visitors per day; the Efteling amusement park receives 14,000.

Snuff is a type of smokeless tobacco product made from finely ground or pulverized tobacco leaves.It is snorted or "sniffed" (alternatively sometimes written as "snuffed") into the nasal cavity, delivering nicotine and a flavored scent to the user (especially if flavoring has been blended with the tobacco). Traditionally, it is sniffed or inhaled lightly after a pinch of snuff is either placed onto the back surface of the hand, held pinched between thumb and index finger, or held by a specially made "snuffing" device.

Snuff originated in the Americas, and was commonly used in Europe by the 17th century. Traditional snuff production consists of a lengthy, multi-step process, in tobacco snuff mills. The selected tobacco leaves are first subject to special tobacco curing or fermentation processes, where they will later provide the individual characteristics and flavor for each type of snuff blend. Snuff is usually scented or flavored, with many blends of snuff requiring months to years of special storage to reach the required maturity. Typical traditional flavors are varieties of blended tobacco leaves considered original "fine snuff" without any addition of scents or essences. Varieties of spice, piquant, fruit, floral, and mentholated (also called "medicated") soon followed, either pure or in blends. Each snuff manufacturer usually has a variety of unique recipes and blends, as well as special recipes for individual customers. Common flavors also include coffee, chocolate, bordeaux, honey, vanilla, cherry, orange, apricot, plum, camphor, cinnamon, rose and spearmint. Modern flavors include bourbon, cola and whisky. Traditional classic German snuff blends are the pungent and sharp Schmalzler and Brasil blends.

The ionones, from greek ἴον ion "violet", are a series of closely related chemical substances that are part of a group of compounds known as rose ketones, which also includes damascones and damascenones. Ionones are aroma compounds found in a variety of essential oils, including rose oil. β-Ionone is a significant contributor to the aroma of roses, despite its relatively low concentration, and is an important fragrance chemical used in perfumery. The ionones are derived from the degradation of carotenoids.

The combination of α-ionone and β-ionone is characteristic of the scent of violets and used with other components in perfumery and flavouring to recreate their scent.

The rose subfamily Rosoideae consists of more than 850 species, including many shrubs, perennial herbs, and fruit plants such as strawberries and brambles. Only a few are annual herbs.

The circumscription of the Rosoideae is still not wholly certain; recent genetic research has resulted in several changes at the genus level and the removal from Rosoideae of some genera (notably Cercocarpus, Cowania, Dryas and Purshia) previously included in the subfamily.

A rosette is a rose-like marking or formation found on the fur and skin of some animals, particularly cats. Rosettes are used to camouflage the animal, either as a defense mechanism or as a stalking tool. Predators use their rosettes to simulate the different shifting of shadows and shade, helping the animals to remain hidden from their prey. Rosettes can be grouped in clusters around other spots, or may appear as blotches on the fur.

Fragaria (/frəˈɡɛəri.ə/) is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as Fragaria × ananassa. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world.

Abbé Jean Michel Gandoger (10 May 1850 – 4 October 1926), was a French botanist and mycologist. He was born in Arnas, the son of a wealthy vineyard owner in the Beaujolais region. Although he took holy orders at the age of 26, he devoted his life to the study of botany, specializing in the genus Rosa. He travelled throughout the Mediterranean, notably Crete, Spain, Portugal, and Algeria, amassing a herbarium of over 800,000 specimens, now kept at the Jardin botanique de Lyon. Gandoger issued and distributed several exsiccata-like series. However, he is notorious for having published thousands of plant species that are no longer accepted. He died at Arnas in 1926.

Father J B Charbonnel published an obituary in the Bulletin de la Societe botanique de France (1927, Vol. 74, 3–11), listing Gandoger's many publications. Plants with the specific epithet of gandogeri are named after him, an example being Carex gandogeri.
