Winter flowering Iris

Description

Iris unguicularis (syn. Iris stylosa), the Algerian iris, is a rhizomatous flowering plant in the genus Iris, native to Greece, Turkey, Western Syria, and Tunisia. It grows to 30 centimetres (12 in), with grassy evergreen leaves, producing pale lilac or purple flowers with a central band of yellow on the falls. The flowers appear in winter and early spring. They are fragrant, with pronounced perianth tubes up to 20 cm (7.9 in) long. This plant is widely cultivated in temperate regions, and numerous cultivars have been selected for garden use, including a slightly more tender white form 'Alba', and a dwarf variety I. unguicularis subsp. cretensis. The cultivar 'Mary Barnard' has gained the Royal Horticultural Society's Award of Garden Merit. In 2013, a chemical analysis study was carried on Iris loczyi and Iris unguicularis as both plants are known as medicinally important. The rhizome of Iris unguicularis contains 1,3-O-diferuloylsucrose, 5,7-dihydroxy-6-methoxychromone, irilone, 4′,5,7-trihydroxy-6-methoxyflavanone, tectorigenin, kaempferol, 4′,5,7-trihydroxy-3′,8-dimethoxyflavanone, 8-methoxyeriodictyol, hispidulin and mangiferin. Iris is a genus of 260–300 species of flowering plants with showy flowers. It takes its name from the Greek word for a 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. As well as being the scientific name, iris is also widely used as a common name for all Iris species, as well as some belonging to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. It is a popular garden flower. The often-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 flower data set outlined by Ronald Fisher in his 1936 paper The use of multiple measurements in taxonomic problems as an example of linear discriminant analysis.
