Genus of flowering plants in the family Iridaceae

Iris is a flowering plant genus of 310 accepted species

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 simple or branched, solid or hollow, and flattened or have a circular cross section. The rhizomatous species usually have 3–10 basal sword shaped leaves growing in dense clumps. The bulbous species also have 2–10 narrow leaves growing from the bulb.

The genus takes its name from the Greek word ἶρις îris "rainbow", which is also the name for the Greek goddess of the rainbow, Iris. Some authors state that the name refers to the wide variety of flower colors found among the many species.

Iris is the largest genus of the family Iridaceae with up to 300 species – many of them natural hybrids. Plants of the World Online lists 310 accepted species from this genus as of 2022. Iris subg. Limniris has been divided into 2 sections; Lophiris (or 'Evansias' or crested iris) and Limniris which was further divided into 16 series.

Nearly all species are found in temperate Northern Hemisphere zones, from Europe to Asia and across North America. Although diverse in ecology, Iris is predominantly found in dry, semi desert, or colder rocky mountainous areas. and Iris foetidissima can be found in woodland, hedge banks and scrub areas.

Narcissus mosaic virus is most commonly known from Narcissus. Wylie et al., 2014, It was, however, unknown in Australia until Wylie et al., 2012, while in Europe the most famous iris garden is arguably the Giardino dell'Iris in Florence (Italy) which every year hosts a well attended iris breeders' competition. Irises, especially the multitude of bearded types, feature regularly in shows such as the Chelsea Flower Show. For garden cultivation, iris classification differs from taxonomic classification. Garden iris are classed as either bulb iris or rhizome iris (called rhizomatous) with a number of further subdivisions. Due to a wide variety of geographic origins, and thus great genetic diversity, cultivation needs of iris vary greatly. Generally, Irises grow well in most garden soil types providing they are well drained, depending on the species. The earliest to bloom are species like I. reticulata and I. reichenbachii, which flower as early as February and March in the Northern Hemisphere, followed by the dwarf forms of I. pumila and others. In May or June, most of the tall bearded varieties start to bloom, such as the German iris and its variety florentina, sweet iris, Hungarian iris, lemon yellow iris (I. flavescens), Iris sambucina, 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 United Kingdom by the British Iris Society. The National Collection of Arthur Bliss Irises is held in Gloucestershire. The American Iris Society is the International Cultivar Registration Authority for Iris, and recognises over 30,000 registered cultivar names.

This section contains the cushion irises or royal irises, a group of plants noted for their large, strongly marked flowers. Between 30 and 60 species are classified in this section, depending on the authority. Species of section Oncocyclus are generally strict endemics, typically occurring in a small number of scattered, disjunct populations, whose geographical isolation is enhanced by their pollination strategy and myrmecochory seed dispersal. Morphological divergence between populations usually follows a cline reflecting local adaptation to environment conditions; furthermore, this largely overlaps divergence between species, making it difficult to identify discrete species boundaries in these irises. Compared with other irises, the cushion varieties are scantily furnished with narrow sickle shaped leaves and the flowers are usually borne singly on the stalks; they are often very dark and in some almost blackish. The cushion irises are somewhat fastidious growers, and to be successful with them they must be planted rather shallow in very gritty well drained soil. They should not be disturbed in the autumn, and after the leaves have withered the roots should be protected from heavy rains until growth starts again naturally.

This section, closely allied to the cushion irises, includes several garden hybrids with species in section Oncocyclus, known as Regelio cyclus irises. They are best planted in September or October in warm sunny positions, the rhizomes being lifted the following July after the leaves have withered.

There are six major subgroupings of the beardless iris, depending on origin. They are divided into Pacific Coast, Siberica, Spuria, Louisiana, Japanese, and other. Beardless rhizomatous iris types commonly found 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 winter 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 popular 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.

One specific species, Iris cristata from North America.

Often called 'junos', this type of iris is one of the more popular bulb irises in cultivation. They are generally earliest to bloom.

Reticulate irises with their characteristic bulbs, including the yellow I. danfordiae, and the various blue purple I. histrioides and I. reticulata, flower as early as February and March. These reticulate bulbed irises are miniatures and popular spring bulbs, being one of the first to bloom in the garden. Many of the smaller species of bulbous iris, being liable to perish from excess of moisture, should have a well drained bed of good 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.

Rhizomes of the German iris (I. germanica) and sweet 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 (absolute) from flowers are sometimes used in aromatherapy as sedative medicines. The dried rhizomes are also given whole to babies to help in teething. Gin brands such as Bombay Sapphire and Magellan Gin use orris root and sometimes iris flowers for flavor and color. For orris root production, iris rhizomes are harvested, dried, and aged for up 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 compound, known in the perfume industry as "iris butter" or orris oil. Iris rhizomes also contain notable amounts of terpenes, and organic acids such as ascorbic acid, myristic acid, tridecylenic acid and undecylenic acid. Iris rhizomes can be toxic. Larger blue flag (I. versicolor) and other species often grown in gardens and widely hybridized contain elevated amounts of the toxic glycoside iridin. These rhizomes can cause nausea, vomiting, diarrhea, and/or skin irritation, but poisonings are not normally fatal. Irises should only be used medicinally under professional guidance.

In water purification, yellow iris (I. pseudacorus) is often used. The roots are usually planted in a substrate (e. g. lava stone) in a reedbed setup. The roots then improve water quality by consuming nutrient pollutants, such as from agricultural runoff. This highly aggressive grower is now considered a noxious weed and prohibited in some states of the US where it is found clogging natural waterways.

The iris has been used in art and as a symbol, including in heraldry. The symbolic meaning has evolved, in Christendom moving from a symbol of Mary mother of Jesus, to a French heraldic sign, the fleur de lis, and from French royalty it spread throughout Europe and beyond.

Vincent van Gogh has painted several famous pictures of irises. The American artist Joseph Mason – a friend of John James Audubon – painted a precise image of what was then known as the Louisiana flag or copper iris (Iris fulva), to which Audubon subsequently 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 work Broken Vows; he followed the principles of the Pre Raphaelite Brotherhood. An ancient belief is that the iris serves as a warning to be heeded, as it was named for the messenger of Olympus. It also conveys images of lost love and silent grief, for young girls were led into the afterlife by the goddess Iris. Broken Vows was accompanied with poetry by Henry Wadsworth Longfellow when it was first exhibited. Contemporary artist George Gessert, who introduced the cultivation of flowers as an art form, has specialised in breeding irises.

Iris nigricans, the black iris is the national flower of Jordan. Iris bismarckiana, the Nazareth Iris, is the symbol of the city of Upper Nazareth. The Iris croatica is the unofficial national flower of Croatia. A stylized yellow iris is the symbol of Brussels, since historically the important Saint Gaugericus Island was carpeted in them. The iris symbol is now the sole feature on the flag of the Brussels Capital Region. In 1998, Iris lacustris, the Dwarf Lake iris, was designated the state wildflower of Michigan, where the vast majority of populations exist. In 1990, the Louisiana iris was voted the state wildflower of Louisiana (see also fleur de lis:United States, New France), though the state flower is the magnolia blossom. An iris — species unspecified — is one of the state flowers of Tennessee. It is generally accepted that the species Iris versicolor, the Purple Iris, is the state flower alongside the wild growing purple passionflower (Passiflora incarnata), the state's other floral emblem. Greeneville, Tennessee, is home to the annual Iris Festival celebrating the iris, local customs, and culture. The species Iris versicolor is also the provincial flower of Quebec, Canada, having replaced the Madonna lily which is not native to the province (see also fleur de lis: Canada). The provincial flag of Québec carries the harlequin blueflag (I. versicolor, iris versicolore in French).

It is thought in China that Iris anguifuga has the ability to keep snakes from entering the garden. It grows all winter, keeping snakes out, but then goes dormant in the spring, allowing the snakes back into the garden. In the autumn, the iris re appears and can stop the snakes again.

In the Homeric Hymn to Demeter, the goddess Persephone and her companion nymphs (the Oceanids along with Artemis and Athena) were gathering flowers such as rose, crocus, violet, iris (also called 'agallis' or ἀγαλλίς (in Greek script), lily, larkspur, and hyacinth in a springtime meadow before she was abducted by the god Hades.) and identified as Iris attica.

In Iran and Kashmir, Iris kashmiriana and Iris germanica are most commonly grown on Muslim grave yards.

French King Clovis I (466–511), when he converted to Christianity, changed his symbol on his banner from three toads to irises (the Virgin's flower). The fleur de lis, a stylized iris, first occurs in its modern use as the emblem of the House of Capet. The fleur de lis has been associated with France since Louis VII adopted it as a symbol in the 12th century. The yellow fleur de lis reflects the yellow iris (I. pseudacorus), common in Western Europe. Contemporary uses can be 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 red fleur de lis in the coat of arms and flag of Florence, Italy, 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 background was the symbol of Florence until the Medici family reversed the colors to signal a change in political power, setting in motion a centuries long and still on going breeding program to hybridize a red iris.

The fleur de lis is the almost universal symbol of Scouting and one of the symbols adopted by the sorority Kappa Kappa Gamma. The Iris versicolor is the official flower of Kappa Pi International Honorary Art Fraternity.

The Iris is one of the flowers listed as birth flower for February.
