Iris (plant) in the context of "Perun"

The Iris flower data set or Fisher's Iris data set is a multivariate data set used and made famous by the British statistician and biologist Ronald Fisher in his 1936 paper The use of multiple measurements in taxonomic problems as an example of linear discriminant analysis. It is sometimes called Anderson's Iris data set because Edgar Anderson collected the data to quantify the morphologic variation of Iris flowers of three related species. Two of the three species were collected in the Gaspé Peninsula "all from the same pasture, and picked on the same day and measured at the same time by the same person with the same apparatus".

The data set consists of 50 samples from each of three species of Iris (Iris setosa, Iris virginica and Iris versicolor). Four features were measured from each sample: the length and the width of the sepals and petals, in centimeters. Based on the combination of these four features, Fisher developed a linear discriminant model to distinguish each species. Fisher's paper was published in the Annals of Eugenics (today the Annals of Human Genetics).

The whiplash or whiplash line is a motif of decorative art and design that was particularly popular in Art Nouveau. It is an asymmetrical, sinuous line, often in an ornamental S-curve, usually inspired by natural forms such as plants and flowers, which suggests dynamism and movement. It took its name from a woven fabric panel "Cyclamen", by the German artist Hermann Obrist (1895) which depicted the stems and roots of the cyclamen plant, which critics dubbed "Coup de Fouet" ('whiplash'). The panel was later reproduced by the textile workshop of the Darmstadt Artists Colony.

Curling whiplash lines were modelled after natural and vegetal forms, particularly the cyclamen, iris, orchid, thistle, mistletoe, holly, water lily, and from the stylized lines of the swan, peacock, dragonfly, and butterfly.

Keukenhof (Dutch pronunciation: [ˈkøːkə(n)ˌɦɔf]; lit. 'Kitchen garden'), also known as the Garden of Europe, is one of the world's largest flower gardens, situated in the municipality of Lisse, in the Netherlands. According to the official website, Keukenhof Park covers an area of 32 hectares (79 acres) and approximately 7 million flower bulbs are planted in the gardens annually. While it is widely known for its tulips, Keukenhof also features numerous other flowers, including hyacinths, daffodils, lilies, roses, carnations and irises.

Keukenhof is located in the province of South Holland, south of Haarlem and southwest of Amsterdam in the area called the "Dune and Bulb Region" (Duin- en Bollenstreek). It is accessible by bus from Haarlem and Leiden train stations as well as Schiphol. Though its grounds are open year-round for private affairs and festivals, Keukenhof is only open to the general public for a world-renowned eight week tulip display from mid-March to mid-May, with peak viewing arriving near mid-April, depending on growing season weather, which varies annually. In 2019, 1.5 million people visited Keukenhof, equivalent to 26,000 visitors per day. By comparison, the Rijksmuseum receives an average of 8,000 visitors per day; the Efteling amusement park receives 14,000.

Iris setosa, known as the beachhead iris, bristle-pointed iris, or a number of other common names, is a species of flowering plant in the genus Iris of the family Iridaceae. It belongs to the subgenus Limniris and the series Tripetalae. It is a rhizomatous perennial found in a wide range across and below the Arctic Circle, including in Alaska, Maine, Canada (including British Columbia, Newfoundland, Quebec and Yukon), Russia (including Siberia), China, Korea, and Japan. The plant has tall branching stems, mid green leaves and violet, purple-blue, violet-blue, blue, or lavender flowers, or, rarely, pink or white flowers.

Iris versicolor or Iris versicolour is also commonly known as the blue flag, harlequin blueflag, larger blue flag, northern blue flag, and poison flag, plus other variations of these names, and in Great Britain and Ireland as purple iris.

It is a species of Iris native to North America, in Eastern Canada and the Eastern United States. It is common in sedge meadows, marshes, and along streambanks and shores. The specific epithet versicolor means "variously coloured".

Asparagales (asparagoid lilies) are a diverse order of flowering plants in the monocots. Under the APG IV system of flowering plant classification, Asparagales are the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species, with members as varied as asparaguses, orchids, yuccas, irises, onions, garlics, leeks, and other alliums, daffodils, snowdrops, amaryllis, agaves, butcher's broom, agapanthuses, Solomon's seal, hyacinths, bluebells, spider plants, grasstrees, aloes, freesias, gladioli, crocuses, and saffrons.

Most species of Asparagales are herbaceous perennials, although some are climbers and some are trees or shrubs. The order also contains many geophytes (bulbs, corms, and various kinds of tuber). The leaves of almost all species form a tight rosette, either at the base of the plant or at the end of the stem, but occasionally along the stem. The flowers are not particularly distinctive, being 'lily type', with six tepals and up to six stamens. One of the defining characteristics (synapomorphies) of the order is the presence of phytomelanin, a black pigment present in the seed coat, creating a dark crust. Phytomelanin is found in most families of the Asparagales (although not in Orchidaceae, thought to be the sister-group of the rest of the order).
