46-527: The garden was first created in 1912 as a school garden, but in 1982 converted into a general green area. Restoration began in 2002, with the aim of gradually re-establishing the garden's 1950s-era features and creating new theme gardens. Current plantings include a rose garden, a medicinal herb garden, and perennials. A cactus house exhibits 300 cacti and succulents . 51°17′46″N 9°28′49″E  /  51.29611°N 9.48028°E  / 51.29611; 9.48028 This Hesse location article

92-698: A group of plants that can be erect shrubs , climbing, or trailing, with stems that are often armed with sharp prickles . Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia , with smaller numbers native to Europe , North America , and Northwest Africa . Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in

138-461: A matrix of fine, but stiff, hairs. Rose hips of some species, especially the dog rose ( Rosa canina ) and rugosa rose ( R. 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. The sharp growths along a rose stem, though commonly called "thorns", are technically prickles , outgrowths of

184-399: A single fruit, and multiple fruits like pineapples are formed from the ovaries of separate flowers that are close together. Because aggregate and multiple fruits are formed from many ripened ovaries together, they are actually infructescences or groups of fruits that are arranged together in a structure. Some fruits, like the apple, are accessory fruits which can include other parts of

230-423: A surrounding fruit, this meaning that juniper and yew "berries" are not fruits, but modified cones . Fruits are responsible for the dispersal and protection of seeds in angiosperms and cannot be easily characterized due to the differences in defining culinary and botanical fruits. After double fertilization and ripening, the ovary becomes the fruit, the ovules inside the ovary become the seeds of that fruit, and

276-564: Is a stub . You can help Misplaced Pages by expanding it . This article related to a park or garden in Germany is a stub . You can help Misplaced Pages by expanding it . Rose See List of Rosa species A rose is either a woody perennial flowering plant of the genus Rosa ( / ˈ r oʊ z ə / ), in the family Rosaceae ( / r oʊ ˈ z eɪ s iː ˌ iː / ), or the flower it bears. There are over three hundred species and tens of thousands of cultivars . They form

322-480: Is common in the Indian subcontinent . The leaves and washed roots are also sometimes used to make tea. In France, there is much use of rose syrup , most commonly made from an extract of rose petals. In the Indian subcontinent , Rooh Afza , a concentrated squash made with roses, is popular, as are rose-flavoured frozen desserts such as ice cream and kulfi . The flower stems and young shoots are edible, as are

368-424: Is commonly used. The oil is transparent pale yellow or yellow-grey in colour. 'Rose Absolute' is solvent-extracted with hexane and produces a darker oil, dark yellow to orange in colour. 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

414-597: Is composed of 140–180 species and divided into four subgenera: Some birds, particularly finches , eat the seeds. Wild roses are host plants for a number of pests and diseases. Many of these affect other plants, including other genera of the Rosaceae . Cultivated roses are often subject to severe damage from insect , arachnid and fungal pests and diseases. In many cases they cannot be usefully grown without regular treatment to control these problems. Roses are best known as ornamental plants grown for their flowers in

460-420: Is embedded or surrounded by the receptacle. This occurs in flowers of the family Lythraceae , which includes the crape myrtles . Such flowers are termed perigynous or half-epigynous . In some classifications, half-inferior ovaries are not recognized and are instead grouped with either the superior or inferior ovaries. More specifically, a half-inferior ovary has nearly equal portions of ovary above and below

506-416: Is known for his detailed watercolours of flowers, particularly 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 , Paul Cézanne and Pierre-Auguste Renoir have paintings of roses among their works. In the 19th century, for example, artists associated

552-412: Is often cited as an example, but close inspection of some pomes (such as Pyracantha ) will show that it is really a half-inferior ovary. Flowers with inferior ovaries are termed epigynous . Some examples of flowers with an inferior ovary are orchids (inferior capsule), Fuchsia (inferior berry), banana (inferior berry), Asteraceae (inferior achene-like fruit, called a cypsela ) and the pepo of

598-406: Is present in the ovary of some plants, near the micropyle of each ovule. It is an outgrowth of the placenta, important in nourishing and guiding pollen tubes to the micropyle. The ovary of some types of fruit is dehiscent ; the ovary wall splits into sections called valves. There is no standard correspondence between the valves and the position of the septa; the valves may separate by splitting

644-474: Is used as a minor source of vitamin C . Diarrhodon (Gr διάρροδον, "compound of roses", from ῥόδων, "of roses" ) is a name given to various compounds in which red roses are an ingredient. The long cultural history of the rose has led to it being used often as a symbol. In ancient Greece , the rose was closely associated with the goddess Aphrodite . In the Iliad , Aphrodite protects the body of Hector using

690-522: Is used in skin products and some makeup products. Rose water has a very distinctive flavour and is used in Middle Eastern , Persian , and South Asian cuisine —especially in sweets such as Turkish delight , barfi , baklava , halva , gulab jamun , knafeh , and nougat . Rose petals or flower buds are sometimes used to flavour ordinary tea , or combined with other herbs to make herbal teas . A sweet preserve of rose petals called gulkand

736-429: 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 omeiensis and 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. There are multiple superior ovaries that develop into achenes . Roses are insect-pollinated in nature. The aggregate fruit of

782-763: The Houses of York and Lancaster in a conflict known as the Wars of the Roses . Subsequently roses of the corresponding colours have been used a emblems for the English counties of Yorkshire and Lancashire . The Tudor rose combines the colours of the roses of York and Lancaster, and is an emblem of then Tudor dynasty and of England . Roses are a favored subject in art and appear in portraits, illustrations, on stamps, as ornaments or as architectural elements. The Luxembourg-born Belgian artist and botanist Pierre-Joseph Redouté

828-572: The epidermis (the outer layer of tissue of the stem), unlike true thorns, which are modified stems . 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 prickles, 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

874-480: The flowering plants , an ovary is a part of the female reproductive organ of the flower or gynoecium . Specifically, it is the part of the pistil which holds the ovule (s) and is located above or below or at the point of connection with the base of the petals and sepals . The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above

920-615: The garden and sometimes indoors. They have also been used for commercial perfumery and commercial cut flower crops. Some are used as landscape plants, for hedging and for other utilitarian purposes such as game cover and slope stabilization. The majority of ornamental roses are hybrids that were bred for their flowers. A few, mostly species roses are grown for attractive or scented foliage (such as Rosa glauca and R. rubiginosa ), ornamental thorns (such as R. sericea ) or for their showy fruit (such as R. moyesii ). Ornamental roses have been cultivated for millennia, with

966-882: The rosary and other devotional prayers in Christianity. Ever since the 1400s, the Franciscans have had a Crown Rosary of the Seven Joys of the Blessed Virgin Mary . In the 1400s and 1500s, the Carthusians promoted the idea of sacred mysteries associated with the rose symbol and rose gardens. Albrecht Dürer 's painting The Feast of the Rosary (1506) depicts the Virgin Mary distributing garlands of roses to her devotees. Roses symbolised

1012-406: The "immortal oil of the rose" and the archaic Greek lyric poet Ibycus praises a beautiful youth saying that Aphrodite nursed him "among rose blossoms". The second-century AD Greek travel writer Pausanias associates the rose with the story of Adonis and states that the rose is red because Aphrodite wounded herself on one of its thorns and stained the flower red with her blood. Book Eleven of

1058-465: The ancient Roman novel The Golden Ass by Apuleius contains a scene in which the goddess Isis , who is identified with Venus , instructs the main character, Lucius, who has been transformed into a donkey , to eat rose petals from a crown of roses worn by a priest as part of a religious procession in order to regain his humanity. French writer René Rapin invented a myth in which a beautiful Corinthian queen named Rhodanthe ("she with rose flowers")

1104-400: The carpels; the number of locules present in a gynoecium may be equal to or less than the number of carpels, depending on whether septa are present. The ovules are attached to parts of the interior ovary walls called the placentae. Placental areas occur in various positions, corresponding to various parts of the carpels that make up the ovary. See Ovule#Location within the plant . An obturator

1150-510: The city of Trieste with a certain rare white rose, and this rose developed as the city's symbol. It was not until 2021 that the rose, which was believed to be extinct, was rediscovered there. In 1986 President Ronald Reagan signed legislation to make the rose the floral emblem of the United States. The rose is often exchanged on St. Valentines Day and is used often as a symbol of such. Ovary (plants)#Superior ovary In

1196-468: The crushed petals of roses. An associated product is rose water which is used for cooking, cosmetics, medicine and religious practices. The production technique originated in Persia and then spread through Arabia and India, and more recently into eastern Europe. In Bulgaria, Iran and Germany, damask roses ( Rosa × damascena 'Trigintipetala') are used. In other parts of the world Rosa × centifolia

1242-437: The definition of a fruit, as not all botanical fruits can be identified as culinary fruits. A ripened ovary may be a fleshy fruit such as a grapefruit or a dry fruit such as a nut. Further complicating this, culinary nuts are not always botanical nuts ; some culinary nuts such as the coconut and almond are another type of fruit called a drupe . In this same way, not all "fruits" are true fruits. A true fruit only consists of

1288-736: The development of rose breeding at her gardens at Malmaison . 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. Roses are a popular crop for both domestic and commercial cut flowers . Generally they are harvested and cut when in bud, and held in refrigerated conditions until ready for display at their point of sale. In temperate climates, cut roses are often grown in greenhouses , and in warmer countries they may also be grown under cover in order to ensure that

1334-499: The development of the wide range of garden roses . The name rose comes from Latin rosa , which was perhaps borrowed from Oscan , from Greek ῥόδον rhódon ( Aeolic βρόδον wródon ), itself borrowed from Old Persian wrd- ( wurdi ), related to Avestan varəδa , Sogdian ward , Parthian wâr . The leaves are borne alternately on the stem. In most species, they are 5 to 15 centimetres (2.0 to 5.9 in) long, pinnate , with (3–) 5–9 (−13) leaflets and basal stipules ;

1380-556: The earliest known cultivation known to date from at least 500 BC in Mediterranean countries, Persia , and China. It is estimated that 30 to 35 thousand rose hybrids and cultivars have been bred and selected for garden use as flowering plants. Most are double-flowered with many or all of the stamens having morphed into additional petals . In the early 19th century the Empress Josephine of France patronized

1426-674: The early Oligocene . Today's garden roses come from 18th-century China. Among the old Chinese garden roses, the Old Blush group is the most primitive, while newer groups are the most diverse. A study of the patterns of natural selection in the genome of roses indicated that genes related to DNA damage repair and stress adaptation have been positively selected, likely during their domestication. This rapid evolution may reflect an adaptation to genome confliction resulting from frequent intra- and inter-species hybridization and switching environmental conditions of growth. The genus Rosa

1472-554: The egg within the ovule becomes the zygote . Double fertilization of the central cell in the ovule produces the nutritious endosperm tissue that surrounds the developing zygote within the seed. Angiosperm ovaries do not always produce a fruit after the ovary has been fertilized. Problems that can arise during the developmental process of the fruit include genetic issues, harsh environmental conditions, and insufficient energy which may be caused by competition for resources between ovaries; any of these situations may prevent maturation of

1518-452: The flower such as the receptacle , hypanthium , perianth , or calyx in addition to the mature and ripened ovary. Locules are chambers within the ovary of the flower and fruits. The locules contain the ovules (seeds), and may or may not be filled with fruit flesh. Depending on the number of locules in the ovary, fruits can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. Some plants have septa between

1564-459: The flowers are not damaged by weather and that pest and disease control can be carried out effectively. Significant quantities are grown in some tropical countries, and these are shipped by air to markets across the world. Some kind of roses are artificially coloured using dyed water, like rainbow roses . Rose perfumes are made from rose oil (also called attar of roses), which is a mixture of volatile essential oils obtained by steam distilling

1610-519: The fragrant alcohols geraniol and L- citronellol and rose camphor, an odorless solid composed of alkanes , which separates from rose oil. β- Damascenone is also a significant contributor to the scent. Rose hips are high in vitamin C , are, after the removal of the irritant hairs, edible raw, and occasionally are made into jam , jelly , marmalade , and soup , or brewed for tea. They are also pressed and filtered to make rose hip syrup. Rose hips are also used to produce rose hip seed oil , which

1656-500: The insertion point, it is superior; if below, inferior. A superior ovary is an ovary attached to the receptacle above the attachment of other floral parts. A superior ovary is found in types of fleshy fruits such as true berries , drupes , etc. A flower with this arrangement is described as hypogynous . Examples of this ovary type include the legumes (beans and peas and their relatives). A half-inferior ovary (also known as “half-superior”, “subinferior,” or “partially inferior,”)

1702-413: The insertion point. Other varying degrees of inferiority can be described by other fractions. For instance, a "one-fifth inferior ovary" has approximately one fifth of its length under the insertion point. Likewise, only one quarter portion of a "three-quarters inferior ovary" is above the insertion. An inferior ovary lies below the attachment of other floral parts. A pome is a type of fleshy fruit that

1748-404: The leaflets usually have a serrated margin, and often a few small prickles on the underside of the stem. Most roses are deciduous but a few (particularly from Southeast Asia ) are evergreen or nearly so. The flowers of most species have five petals, with the exception of Rosa omeiensis and Rosa sericea , which usually have only four. Each petal is divided into two distinct lobes and

1794-534: The ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain , to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm . Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules , they produce naked seeds that do not have

1840-534: The ovary. Fruits are important in the dispersal and protection of seeds, and variation in fruit shape or size results from an evolutionary response that aids in the dispersal of seeds in different environments. For example, the seeds of large fleshy fruits are often dispersed through endozoochory ; this means that animals consume the fleshy fruit and as a result disperse its seeds with their movement. The seeds of fruits can be dispersed by endozoochory, gravity, wind, or other means. There are some complications to

1886-756: The petals (sans the white or green bases). The latter are usually used as flavouring or to add their scent to food. Other minor uses include candied rose petals. Rose creams (rose-flavoured fondant covered in chocolate , often topped with a crystallised rose petal) are a traditional English confectionery widely available from numerous producers in the UK. Under the American Federal Food, Drug, and Cosmetic Act , there are only certain Rosa species, varieties, and parts are listed as generally recognized as safe (GRAS). The rose hip , usually from R. canina ,

1932-662: The presence of prickles, roses are frequently browsed by deer . A few species of roses have only vestigial prickles that have no points. Plant geneticist Zachary Lippman of Cold Spring Harbor Laboratory found that prickles are controlled by the LOG gene. Blocking the LOG gene in roses reduced the thorns (large prickles) into tiny buds. The oldest remains of roses are from the Late Eocene Florissant Formation of Colorado. Roses were present in Europe by

1978-415: The ripened ovary and its contents. Fruits can be separated into three major categories: simple fruits , aggregate fruits , and multiple fruits . Simple fruits like oranges are formed from a single ovary which may or may not consist of multiple parts, while aggregate and multiple fruits are formed from several ovaries together. Aggregate fruits like raspberries are the ripened ovaries of one flower that form

2024-466: The rose is a berry-like structure called a rose hip . Many of the domestic cultivars do not produce hips, as the flowers 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

2070-401: The septa (septicidal dehiscence), or by spitting between them (loculicidal dehiscence), or the ovary may open in other ways, as through pores or because a cap falls off. The terminology of the positions of ovaries is determined by the insertion point , where the other floral parts ( perianth and androecium ) come together and attach to the surface of the ovary. If the ovary is situated above

2116-592: Was besieged inside a temple of Artemis by three ardent suitors who wished to worship her as a goddess; the god Apollo then transformed her into a rosebush. Following the Christianization of the Roman Empire , the rose became identified with the Virgin Mary . The colour of the rose and the number of roses received has symbolic representation. The rose symbol eventually led to the creation of
