Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 the cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or green in garden types), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten parts with approximately 50 species. The number of varieties has assorted, depending how they are categorized, credited to similarity between varieties and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the real name Narcissus is unknown, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the youth of this name who fell deeply in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The types are local to meadows and woods in southern European countries and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated 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 also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as trim blossoms so that ornamental plant life in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide flower of Wales and the image of tumors charities in many countries. The looks of the wild flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The plant stem usually bears a solitary blossom, but occasionally a cluster of flowers (umbel). The plants, that are conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang up down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry involves a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant following the leaves and blossom stem die back and has contractile roots that move it down further in to the soil. The flower leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from summer season to late winter, flowering in the spring and coil, though a few varieties are autumn flowering.
