Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some 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 yellow (orange or green in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten areas with roughly 50 species. The true quantity of kinds has assorted, depending how they are categorized, credited to similarity between species 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 exact source of the name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern European countries and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as slice plants so that ornamental vegetation in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety 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 in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the nationwide blossom of Wales and the mark of tumor charities in many countries. The looks of the outrageous flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the bulb. The plant stem usually bears a solitary rose, but sometimes a cluster of flowers (umbel). The flowers, which are usually conspicuous and white or yellowish, both or hardly ever green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries involves a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant following the leaves and rose stem die again and has contractile origins that yank it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most species are dormant from warmer summer months to past due winter, flowering in the spring, though a few species are fall months flowering.
