Iris spuria is a species of the genus Iris, part of a subgenus series known as Limniris and in the Series Spuriae. It is a rhizomatous perennial plant, from Europe, Asia and Africa. It has purple or lilac flowers, and slender, elongated leaves. It is widely cultivated as an ornamental plant in temperate regions and hybridized for use in the garden. It has several subspecies; Iris spuria subsp. carthaliniae (Achv. & Mirzoeva) B.Mathew, Iris spuria subsp. demetrii (Achv. & Mirzoeva) B.Mathew, Iris spuria subsp. maritima (Dykes) P.Fourn. and Iris spuria subsp. musulmanica (Fomin) Takht. It used to have 3 other subspecies, which have now been re-classified as separate species; Iris spuria subsp. halophila (now Iris halophila), Iris spuria ssp. sogdiana (now Iris halophile subsp. sogdiana) and Iris spuria subsp. notha (now Iris notha). It has many common names including 'blue iris', 'Spurious Iris' and 'bastard iris'.
It has erect, slender, sword-shaped, acuminate (ending in a point), glaucous green to blue green basal leaves. They can grow up to between 25–90 cm (10–35 in) long and 5–12 mm wide. They are normally nearly as long as the flowering stem. After the plant has flowered and set seed, the leaves die in the late summer.
The stem also has keeled, lanceolate, green, spathes (leaves of the flower bud) (or bracts). These are 40–80 cm (16–31 in) long, and have a membranous tip. The upper cauline (on stem) leaves are shorter than internodes.
The stems (and branches) hold 1-4 terminal (top of stem) flowers, in summer, between May and July. They flower after Iris germanica and are similar in form to Iris x hollandica.
It has large, lightly scented, flowers that are up to 6–12 cm (2–5 in) in diameter, and they come in shades of lilac, mauve-blue, violet-blue, purple-blue, violet, or blue.
It has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals, known as the 'standards'. The falls are broadly ovate, elliptic, or orbicular with a long claw (section leading to the stem). The fall is 4.5–6 cm (2–2 in) long, and 2.5 cm wide. They have purple or violet veining, and a central yellow or white stripe or signal area.
After the iris has flowered, it produces an oblong-ovate, hexagonal, (2.5–4 cm long) seed capsule in September. It has a long beak-like appendage on the top, and 6 visible, longitudinal groves. Inside the capsule, are light brown, angular seeds, with a loose membranous testa (surface).
In 2007, a chemical analysis was carried out on Iris spuria rhizomes, several compounds were isolated 12a-dehydrorotenoid 1, 11-dihydroxy-9, 10-methylenedioxy-12a-dehydrorotenoid, together with a new isoflavonoid glycoside tectorigenin-7-O-beta-glucosyl-4'-O-beta-glucoside, with 4 other known compounds, tectorigenin, tectorigenin-7-O-beta-glucosyl (1 --> 6) glucoside, tectoridin (a tectorigenin-7-O-beta-glucoside) and tectorigenin-4'-O-beta-glucoside.
In 2012, five Iris species (Iris pseudacorus, Iris crocea, Iris spuria, Iris orientalis and Iris ensata) were studied, to measure the flavonoids and phenolics content with the rhizomes. Iris pseudacorus had the highest content and Iris crocea had the lowest content.
In July 2014, eight Irises from the Limniris section (Iris crocea, Iris ensata, Iris orientalis, Iris pseudacorus, Iris setosa, Iris sibirica with its cultivars ´Supernatural´ and ´Whiskey White´, Iris spuria and Iris versicolor) were studied to find 12 chemical compounds (flavonoids, phenols, quinones, tannins, saponins, cardiac glycosides, terpenoids, alkaloids, steroids, glycosides and proteins.
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. It has been counted several times; 2n=22, Westergaraard, 1938; 2n=22, Lenz & Day, 1963; 2n=40, Banerji, 1970; 2n=40, Sharma & Sar., 1971; 2n=40, Roy et al., 1988. The chromosome count is normally stated as 2n=22. 
It is prononced as 'EYE-ris SPUR-ee-uh'.
Due to the wide distribution of the species, it has many different common names, including; 'Spurious Iris', 'false iris', 'bastard iris', 'blue iris' (in England), 'butterfly iris' (also in England), 'meadow marsh iris', 'iris steppe', 'iris des steppes' (in France), 'Steppen-Schwertlilie' (in Germany), and 'dansk iris' (in Sweden). and 'salt iris' (also in Sweden).
Another is 'seashore iris', but this probably applies to Iris spuria subsp. maritima. Also 'salt iris', and 'salt marsh iris', but this applies to Iris halophila (formerly a subspecies).
On 4 November 1876, John Gilbert Baker described the Iris, in The Gardeners' Chronicle on page583. An illustration of the iris was published in 1981, in Grey-Wilson and Mathew, Bulbs plate28. It was then published in 1982, by P.J. Redoute, Liles and related flowers 183.
It has several subspecies; Iris spuria subsp. demetrii (Achv. & Mirzoeva) B.Mathew, Iris spuria subsp. demetrii (Achv. & Mirzoeva) B.Mathew, Iris spuria subsp. maritima (Dykes) P.Fourn. and Iris spuria subsp. musulmanica (Fomin) Takht. It used to have 3 other subspecies, which have now be re-classified as separate species; Iris spuria subsp. halophila (now Iris halophila), Iris spuria ssp. sogdiana (now Iris halophila var. sogdiana and Iris spuria subsp. notha (now Iris notha).
It has been grown and cultivated in Britain since 1573, It had naturalised in south Lincolnshire in 1836. Another colony was growing in Dorset, but in 1972 it was deliberately vandalised and damaged fatally.
It was originally found on 10 July 1955 growing in Limhamm, Skane in Sweden. It was later published in Botanical Notices in 1958.
Distribution and habitat
It is found within Africa, in Algeria. Within temperate Asia, in the Western Asia regions of Afghanistan, Iran and Turkey. In the Caucasus regions of Armenia, Azerbaijan, Georgia, Ciscaucasia and Dagestan. In the Russian, Siberian region of Altay, Chelyabinsk, Gorno-Altay, Kurgan, Novosibirsk, Omsk and Tomsk. In the Middle Asia region of Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan and Mongolia. In China, with the provinces of Gansu and Xinjiang. Within tropical Asia, it is found in the Indian sub-continental regions of Jammu, Kashmir and Pakistan. Within Europe, it is found in the northern European regions of Denmark and Sweden. In the middle European regions of Austria, Czechoslovakia, Germany and Hungary. In the eastern European regions of Moldova, Bashkortostan, Ukraine, and Serbia. In the southern European regions of Romania, France and Spain.
It can be found naturalised in damp, grassy places, by ditches, on banks and on roadside verges.
The iris is generally listed as of 'Least Concern' on 26 April 2013 in most European countries. But it is listed as rare or endangered in some.
In Russia, the digging up of wild iris rhizomes is strictly prohibited.
In Czechoslovakia, it has mixed fortunes. In the region of Moravia, it is now regarded as extinct. In the Slovak Republic, it is classified as a 'critically endangered' species, and listed in the Red Book, with the meadows to the north and east of Štúrovo, now protected. It is currently found in about 10 locations in Podunajskej lowlands, near Komárno and Sturova Nitra.
It is tolerant to most garden soils, it will grow on wet soils, saline soils, and saline marshes. It prefers well drained, humus rich soils. It is tolerant of acid soils, but prefers neutral soils.
Hybrids and Cultivars
Due to the wide range of species, (with various tolerances for heat, salt or cold resistance), they have been very useful to plant breeders. Many of the modern cultivars have been breed with larger flowers in a wider range of colours than wild species.
Known Iris spuria cultivars include; 'Adobe Sunset' (hybridized by McCown, 1976), 'AJ Balfour', 'Albulus', 'Archie Owen' (hybridized by Hager, 1970), 'Barbara's Kiss' (hybridized by McCown, 1981), 'Belise' (hybridized by Simonet, 1964), 'Belissinado' (hybridized by Corlew, 1988), 'Betty Cooper' (hybridized by McCown, 1981), Iris 'Betty My Love' (hybridized by Wickenkamp, 1988), Iris 'Blue Lassie' (hybridized by Niswonger, 1978), 'Cambridge Blue', 'Cheroke Chief', 'Clarke Cosgrove', 'Custom Design', 'Daenaensis', 'Danica', 'Dawn Candle', 'Georgian Delicacy', 'Halophila lutea', 'Imperial Bronze', 'Media Lux', 'Norton Sunlight', 'Protege', 'Monspur', 'Premier', and 'Red Clover'.
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.
