Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with approximately 50 species. The true range of kinds has mixed, depending about how they are labeled, thanks to similarity between hybridization and varieties. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is undiscovered, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as chop blooms so when ornamental vegetation in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of these family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the national blossom of Wales and the mark of cancer tumor charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the bulb. The place stem bears a solitary rose, but once in a while a cluster of plants (umbel). The blossoms, which are conspicuous and white or yellow usually, both or almost never renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The plants may hang down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry involves a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant after the leaves and bloom stem die back and has contractile root base that pull it down further into the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summertime to overdue winter, flowering in the spring and coil, though a few species are fall months flowering.
