Iris is a genus of 260–300[1] [2] species of flowering plants with showy flowers. It takes its name from the Greek discussion for a rainbow, which is also the proper noun for the Greek goddess of the rainbow, Iris. Some authors country that the name refers to the broad multifariousness of blossom colors plant among the many species.[3] Equally well equally beingness the scientific proper noun, iris is also widely used equally a common name for all Iris species, likewise as some belonging to other closely related genera. A mutual name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. It is a pop garden bloom.
The frequently-segregated, monotypic genera Belamcanda (blackberry lily, I. domestica), Hermodactylus (snake's head iris, I. tuberosa), and Pardanthopsis (vesper iris, I. dichotoma) are currently included in Iris.
Three Iris varieties are used in the Iris blossom data set outlined by Ronald Fisher in his 1936 paper The use of multiple measurements in taxonomic problems equally an example of linear discriminant analysis.[4]
Description [edit]
Illustration of an iris flower with highlighted parts of the flower
Irises are perennial plants, growing from creeping rhizomes (rhizomatous irises) or, in drier climates, from bulbs (bulbous irises). They have long, erect flowering stems which may be unproblematic or branched, solid or hollow, and flattened or have a round cross-department. The rhizomatous species unremarkably have 3–10 basal sword-shaped leaves growing in dense clumps. The bulbous species have cylindrical, basal leaves.[ commendation needed ]
Flower [edit]
The inflorescences are in the shape of a fan and comprise 1 or more than symmetrical six-lobed flowers. These grow on a pedicel or peduncle. The 3 sepals,[5] which are usually spreading or droop down, are referred to as "falls". They expand from their narrow base (the "claw" or "haft"[6]), into a broader expanded portion ("limb" or "bract"[seven]) and tin can be adorned with veining, lines or dots. In the center of the blade, some of the rhizomatous irises have a "beard" (a tuft of brusk upright extensions growing in its midline),[eight] which are the plant'southward filaments.[9] [ better source needed ]
The three,[v] sometimes reduced, petals stand upright, partly behind the sepal bases. They are called "standards". Some smaller iris species have all half dozen lobes pointing straight outwards, but by and large limb and standards differ markedly in appearance. They are united at their base into a floral tube that lies above the ovary (known as an epigynous or inferior ovary). The three styles[five] divide towards the noon into petaloid branches; this is significant in pollination.[ citation needed ]
The iris flower is of involvement as an case of the relation betwixt flowering plants and pollinating insects. The shape of the flower and the position of the pollen-receiving and stigmatic surfaces on the outer petals form a landing-stage for a flying insect, which in probing for nectar, will kickoff come into contact with the perianth, and so with the three[five] stigmatic stamens in one whorled surface which is borne on an ovary formed of three carpels. The shelf-like transverse projection on the inner whorled underside of the stamens is beneath the overarching style arm beneath the stigma, so that the insect comes in contact with its pollen-covered surface only afterwards passing the stigma; in backing out of the bloom it will come in contact only with the not-receptive lower face of the stigma. Thus, an insect begetting pollen from ane blossom will, in inbound a 2nd, deposit the pollen on the stigma; in backing out of a flower, the pollen which it bears will not exist rubbed off on the stigma of the same flower.[10]
The iris fruit is a capsule which opens up in iii parts to reveal the numerous seeds inside. In some species, the seeds bear an aril. Such as Iris stolonifera which equally lite brown seeds that take thick white aril (or coatings).[11]
Taxonomy [edit]
Iris is the largest genus of the family Iridaceae with up to 300 species – many of them natural hybrids.[12] Mod classifications, starting with Dykes (1913), accept subdivided them. Dykes referred to the major subgroupings every bit sections. Subsequent authors such as Lawrence (1953) and Rodionenko (1987) accept generally chosen them subgenera, while essentially retaining Dykes' groupings, using six subgenera further divided into twelve sections. Of these, section Limneris (subgenus Limneris) was further divided into sixteen series. Similar some older sources, Rodionenko moved some of the bulbous subgenera (Xiphium, Scorpiris and Hermodactyloides) into separate genera (Xiphion, Juno and Iridodictyum respectively), simply this has not been accepted by later writers such every bit Mathew (1989), although the latter kept Hermodactylus every bit a distinct genus, to include Hermodactylus tuberosus, now returned to Hermodactyloides as Iris tuberosa.[12]
Rodionenko besides reduced the number of sections in subgenus Iris, from six to two, depending on the presence (Hexapogon) or absence (Iris) of arils on the seeds, referred to as arilate or nonarilate. Taylor (1976) provides arguments for not including all arilate species in Hexapogon.[12]
In general, modern classifications usually recognise 6 subgenera, of which five are restricted to the Old Globe; the 6th (subgenus Limniris) has a Holarctic distribution. The two largest subgenera are further divided into sections. The Iris subgenus has been divided into half-dozen sections; bearded irises (or pogon irises), Psammiris, Oncocyclus, Regelia, Hexapogon and Pseudoregelia.[thirteen] Iris subg. Limniris has been divided into two sections; Lophiris (or 'Evansias' or crested iris) and Limniris which was farther divided into 16 series.[14]
Subgeneric division [edit]

- Iris (Bearded rhizomatous irises)
- Limniris (Beardless rhizomatous irises)
- Xiphium (Smooth-bulbed bulbous irises: Formerly genus Xiphion)
- Nepalensis (Bulbous irises: Formerly genus Junopsis)
- Scorpiris (Smooth-bulbed bulbous irises: Formerly genus Juno)
- Hermodactyloides (Reticulate-bulbed bulbous irises: Formerly genus Iridodictyum)
Sections, serial and species [edit]
Distribution and habitat [edit]
Well-nigh all species are found in temperate Northern hemisphere zones, from Europe to Asia and across N America. Although diverse in ecology, Iris is predominantly constitute in dry, semi-desert, or colder rocky mountainous areas.[12] Other habitats include grassy slopes, meadowlands, bogs and riverbanks.[ citation needed ]
Cultivation [edit]
Iris is extensively grown as ornamental plant in abode and botanical gardens. Presby Memorial Iris Gardens in New Bailiwick of jersey, for case, is a living iris museum with over 10,000 plants, while in Europe the most famous iris garden is arguably the Giardino dell'Iris in Florence (Italia) which every twelvemonth hosts a well attended iris breeders' competition. Irises, particularly the multitude of bearded types, feature regularly in shows such equally the Chelsea Flower Evidence.
For garden cultivation, iris nomenclature differs from taxonomic classification. Garden iris are classed as either bulb iris or rhizome iris (chosen rhizomatous) with a number of farther subdivisions. Due to a wide variety of geographic origins, and thus bully genetic diversity, cultivation needs of iris vary profoundly.
Iris grow well in most any garden soil types providing they are well-drained. The earliest to flower are species like I. junonia and I. reichenbachii, which flower as early on as February and March in the Northern Hemisphere, followed past the dwarf forms of I. pumila, and so past nearly of the tall bearded varieties, such every bit the German iris and its variety florentina, sweet iris, Hungarian iris, lemon-xanthous iris (I. flavescens), Iris sambucina, I. amoena, and their natural and horticultural hybrids such as those described under names like I. neglecta or I. squalens and best united under I. × lurida.
The iris is promoted in the Britain by the British Iris Society.[15] The national collection of Arthur Bliss Irises is held in Gloucestershire.[16]
Disguised rhizome iris [edit]
'Amethyst Flame'. Note prominent "beard".
Tall Bearded Iris 'Barocco'
Bearded iris are classified as dwarf, alpine, or aril. In Europe, the most commonly found garden iris is a hybrid iris (falsely chosen German iris, I. germanica which is sterile) and its numerous cultivars. Diverse wild forms (including Iris aphylla)[17] and naturally occurring hybrids of the Sweet iris (I. pallida) and the Hungarian iris (I. variegata) class the basis of almost all modern hybrid bearded irises. Median forms of bearded iris (intermediate bearded, or IB; miniature alpine disguised, or MTB; etc.) are derived from crosses between tall and dwarf species like Iris pumila.
Bearded iris are easy to cultivate and propagate and take become very popular in gardens. A pocket-size selection is usually held by garden centres at appropriate times during the season, just there are thousands of cultivars bachelor from specialist suppliers (more than 30 000 cultivars only for the tall bearded irises !). They are all-time planted every bit blank root plants in late summer, in a sunny open position with the rhizome visible on the surface of the soil and facing the dominicus. They should be divided in summer every two or iii years, when the clumps become congested.
A truly red disguised iris, like a truly blue rose, remains an unattained goal despite frequent hybridizing and selection. There are species and selections, most notably based on the beardless rhizomatous Copper iris (I. fulva), which accept a relatively pure red color. However, getting this color into a modern disguised iris breed has proven very difficult, and thus, the vast majority of irises are in the purple and blueish range of the color spectrum, with xanthous, pink, orangish and white breeds also available.
AGM cultivars [edit]
The post-obit is a selection of bearded irises that take gained the Royal Horticultural Society's Award of Garden Merit:
- 'Alizes'[eighteen] (tall bearded, bluish & white)
- 'Bumblebee Deelite'[19] (miniature tall bearded, yellowish/purple)
- 'Early on Light'[xx] (tall bearded, pale yellow)
- 'Jane Phillips'[21] (tall bearded, stake blueish)
- 'Langport Wren'[22] (intermediate bearded, maroon)
- 'Maui Moonlight'[23] (intermediate bearded, stake yellow)
- 'Orinoco Menstruum'[24] (edge disguised, white/violet)
- 'Raspberry Blush'[25] (intermediate bearded, pink)
- 'Sarah Taylor'[26] (dwarf bearded, pale yellow)
- 'Thornbird'[27] (alpine bearded, pale yellow)
- 'Titan's Glory'[28] (tall bearded, deep blue)
Bearded iris Oncocyclus section [edit]
This section contains the cushion irises or royal irises, a group of plants noted for their big, strongly marked flowers. Between thirty and 60 species are classified in this department, depending on the authority. Species of section Oncocyclus are generally strict endemics, typically occurring in a small-scale number of scattered, disjunct populations, whose geographical isolation is enhanced by their pollination strategy and myrmecochory seed dispersal. Morphological deviation between populations unremarkably follows a cline reflecting local adaptation to environment conditions; furthermore, this largely overlaps deviation between species, making it difficult to identify discrete species boundaries in these irises.[29] [30] Compared with other irises the absorber varieties are scantily furnished with narrow sickle-shaped leaves and the flowers are normally borne singly on the stalks; they are often very dark and in some almost blackish.[31] The cushion irises are somewhat fastidious growers, and to be successful with them they must be planted rather shallow in very gritty well-tuckered soil. They should non be disturbed in the fall, and afterward the leaves have withered the roots should be protected from heavy rains until growth starts again naturally.
Bearded iris Regelia section [edit]
This section, closely allied to the absorber irises, includes several garden hybrids with species in department Oncocyclus, known every bit Regelio-cyclus irises. They are best planted in September or October in warm sunny positions, the rhizomes existence lifted the post-obit July after the leaves have withered.
Beardless rhizome iris (subgenus Limniris) [edit]
There are six major subgroupings of the beardless iris, depending on origin. They are divided into Pacific Declension, Siberica, Spuria, Louisiana, Japanese, and other.
Beardless rhizomatous iris types ordinarily plant in the European garden are the Siberian iris (I. sibirica) and its hybrids, and the Japanese Iris (I. ensata) and its hybrids. "Japanese iris" is also a catch-all term for the Japanese iris proper (hanashōbu), the blood iris (I. sanguinea, ayame) and the rabbit-ear iris (I. laevigata, kakitsubata). I. unguicularis is a late-wintertime-flowering species from Algeria, with sky-blue flowers with a yellow streak in the centre of each petal, produced from Winter to Spring. Yet another beardless rhizomatous iris pop in gardening is I. ruthenica, which has much the same requirements and characteristics as the tall bearded irises. In North America, Louisiana iris and its hybrids are often cultivated.
Crested rhizome iris (subgenus Limniris) [edit]
One specific species, Iris cristata from North America.
Bulbing juno iris (subgenus Scorpiris) [edit]
Ofttimes called 'junos', this type of iris is i of the more popular seedling irises in cultivation. They are generally earliest to bloom.
Bulbing European iris (subgenus Xiphium) [edit]
This group includes irises generally of European descent, and are besides classified equally Dutch, English, or Spanish iris.
- Iris reticulata and Iris persica, both of which are fragrant, are also popular with florists.
- Iris xiphium, the Castilian Iris (also known equally Dutch Iris) and
- Iris latifolia, the English Iris. Despite the common names both the Spanish and English iris are of Spanish origin, and have very showy flowers, and then they are popular with gardeners and florists. They are among the hardier bulbous irises, and can be grown in northern Europe. They require to be planted in thoroughly drained beds in very light open soil, moderately enriched, and should have a rather sheltered position. Both these present a long series of cute varieties of the virtually various colours, flowering in May, June and July, the smaller Spanish iris being the earlier of the two.
Bulbing reticulate iris (subgenus Hermodactyloides) [edit]
Reticulate irises with their characteristic bulbs, including the yellow I. danfordiae, and the various blue-imperial I. histrioides and I. reticulata, flower as early as Feb and March. These reticulate-bulbed irises are miniatures and pop spring bulbs, being 1 of the showtime to bloom in the garden. Many of the smaller species of bulbous iris, beingness liable to perish from backlog of moisture, should have a well-drained bed of proficient but porous soil made up for them, in some sunny spot, and in winter should be protected by a covering of half-decayed leaves or fresh coco-fiber.

Uses [edit]
Aromatic rhizomes [edit]
Bombay Sapphire gin contains flavoring derived from particular bearded iris species Iris germanica and Iris pallida.
Rhizomes of the German Iris (I. germanica) and Sweetness Iris (I. pallida) are traded as orris root and are used in perfume and medicine, though more common in ancient times than today. Today Iris essential oil (accented) from flowers are sometimes used in aromatherapy as allaying medicines. The stale rhizomes are also given whole to babies to assist in teething. Gin brands such as Mumbai Sapphire and Magellan Gin use orris root and sometimes iris flowers for flavor and color.[32] [33]
For orris root production, iris rhizomes are harvested, dried, and aged for upward to 5 years. In this time, the fats and oils inside the roots undergo degradation and oxidation, which produces many fragrant compounds that are valuable in perfumery. The scent is said to be similar to violets. The aged rhizomes are steam-distilled which produces a thick oily chemical compound, known in the perfume industry as "iris butter" or orris oil.[ citation needed ]
Iris rhizomes too comprise notable amounts of terpenes, and organic acids such as ascorbic acid, myristic acid, tridecylenic acid and undecylenic acrid. Iris rhizomes tin be toxic. Larger bluish flag (I. versicolor) and other species often grown in gardens and widely hybridized incorporate elevated amounts of the toxic glycoside iridin. These rhizomes can crusade nausea, airsickness, diarrhea, and/or skin irritation, simply poisonings are not normally fatal. Irises should only be used medicinally under professional guidance.[ commendation needed ]
Water purification [edit]
In water purification, yellow iris (I. pseudacorus) is often used. The roots are unremarkably planted in a substrate (e.g. lava-stone) in a reedbed-setup. The roots then meliorate water quality past consuming nutrient pollutants, such as from agricultural runoff. This highly aggressive grower is now considered a noxious weed and banned in some states of the U.s. where it is found clogging natural waterways.[ commendation needed ]
In civilisation [edit]
The Iris is one of the flowers listed as nascence bloom for Feb.[34] In Christianity, the iris represents Our Lady of Sorrows as its abrupt leaves are like swords.[35]
The Iris croatica is the unofficial National Flower of Croatia .[36] Iris nigricans, the Black Iris is the national blossom of Jordan.[37] Iris bismarckiana, the Nazareth Iris, is the symbol of the city of Upper Nazareth.[38] [39]
In 1998, Iris lacustris, the Dwarf Lake Iris was designated the state wildflower of Michigan,[40] [41] where the vast majority of populations exist.[42]
In 1990, the Louisiana iris was voted the state wildflower of Louisiana,[43] though the country blossom is the magnolia blossom.[44]
In Islamic republic of iran and Kashmir,[45] Iris kashmiriana and Iris germanica [46] are well-nigh commonly grown on Muslim[14] grave yards.[47] [48] [49]
An iris — species unspecified — is ane of the country flowers of Tennessee. Information technology is more often than not accepted that the species Iris versicolor, the Majestic Iris is the land blossom[50] aslope the wild-growing purple passionflower (Passiflora incarnata), the state's other floral emblem. Greeneville, Tennessee, is abode to the almanac Iris Festival celebrating the iris, local customs, and culture.[51] The species Iris versicolor is also the provincial flower of Quebec, having replaced the Madonna lily which is not native to the province.[52] and it is the official flower of Kappa Pi International Honorary Art Fraternity.[53]
The artist George Gessert has specialised in convenance irises.[54]
The artist Vincent van Gogh painted several famous pictures of irises.[55]
The American creative person Joseph Mason – a friend of John James Audubon – painted a precise paradigm of what was then known as the Louisiana flag or copper iris (Iris fulva), to which Audubon after added two Northern paraula birds (Parula americana) for inclusion as Plate 15 in his Birds of America.
The artist Philip Hermogenes Calderon painted an iris in his 1856 piece of work Cleaved Vows; he followed the principles of the Pre-Raphaelite Alliance. An aboriginal conventionalities is that the iris serves as a warning to be heeded, every bit information technology was named for the messenger of Olympus. It also conveys images of lost dear and silent grief, for young girls were led into the afterlife by Iris. Cleaved Vows was accompanied with poetry by Henry Wadsworth Longfellow when information technology was outset exhibited.[56]
French King Clovis I (466–511), when he converted to Christianity, changed his symbol on his banner from 3 toads to irises (the Virgin'due south bloom).[57]
The fleur-de-lis, a stylized iris, first occurs in its mod use as the keepsake of the Firm of Capet. The fleur-de-lis has been associated with French republic since Louis VII adopted it as a symbol in the 12th century. The yellow fleur-de-lis reflects the yellowish iris (I. pseudacorus), common in Western Europe. Contemporary uses can exist seen in the Quebec flag and the logo of the New Orleans Saints professional football team and on the flag of Saint Louis, Missouri.
The reddish fleur-de-lis in the coat-of-arms and flag of Florence, Italia, descends from the white iris which is native to Florence and which grew even in its city walls. This white iris displayed against a red groundwork was the symbol of Florence until the Medici family reversed the colors to signal a alter in political power, setting in motion a centuries-long and still on-going convenance program to hybridize a red iris.
The fleur-de-lis is the near-universal symbol of Scouting and ane of the symbols adopted by the sorority Kappa Kappa Gamma.
A stylized yellow iris is the symbol of Brussels, since historically the of import Saint Gaugericus Island was carpeted in them.[58] The iris symbol is now the sole feature on the flag of the Brussels-Capital Region. The provincial bloom of Québec (Canada) is the harlequin blueflag (I. versicolor), called iris versicolore in French.
It is thought in Red china, that Iris anguifuga has the ability to proceed snakes from inbound the garden. It grows all winter, keeping snakes out, but then goes dormant in the jump, assuasive the snakes back into the garden. In the autumn, the iris re-appears and tin stop the snakes again.[59] [60]
In the Homeric Hymn to Demeter, the goddess Persephone and her companion nymphs (the Oceanids forth with Artemis and Athena) were gathering flowers such as rose, crocus, violet, iris (also called 'agallis' or ἀγαλλίς (in Greek script),[61] lily, larkspur,[62] and hyacinth[63] in a springtime meadow earlier she was abducted past the god Hades.[62]
It has been suggested that the 'agallis' mentioned was a dwarf iris, as described by leaf and root shape,[64]) and identified as Iris attica.[65] [66]
