Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or green in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The number of kinds has assorted, depending on how they are classified, credited to similarity between species and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the real name Narcissus is unidentified, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The types are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to 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, 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 following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as lower blooms so that ornamental plants in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi produce 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 utilization in traditional healing and has resulted in 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 various cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the national rose of Wales and the mark of tumor charities in many countries. The looks of the untamed flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the light bulb. The seed stem usually bears a solitary rose, but once in a while a cluster of blooms (umbel). The flowers, which can be usually conspicuous and white or yellowish, sometimes both or almost never renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and rose stem die back again and has contractile origins that pull it down further into the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer season to later winter, flowering in the spring and coil, though a few kinds are fall months flowering.
