Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 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 yellowish (orange or red in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten parts with about 50 species. The number of varieties has mixed, depending how they are categorised, scheduled to similarity between varieties and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the true name Narcissus is undiscovered, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own reflection. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released in to the Far East to the tenth hundred years prior. 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, nematodes and mites. 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 overdue 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as slash bouquets so that ornamental crops in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the nationwide blossom of Wales and the mark of tumor charities in many countries. The looks of the wild flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light bulb. They regrow in the following time from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The seed stem usually bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The bouquets, that happen to be usually conspicuous and white or yellowish, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries consists of a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and flower stem die again and has contractile roots that move it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summer time to overdue winter, flowering in the planting season, though a few species are fall months flowering.
