Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 with a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden kinds), with either standard or contrasting coloured corona and tepals.

Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten portions with about 50 species. The true quantity of species has mixed, depending on how they are categorized, scheduled to similarity between kinds and hybridization. The genus arose some time 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 mysterious, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the junior of that name who fell deeply in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.

The kinds are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before 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 others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as cut bouquets as ornamental crops in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members with their family, narcissi produce a true 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide blossom of Wales and the symbol of cancer charities in many countries. The appearance of the outdoors flowers in planting season is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.

The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The place stem bears a solitary blossom, but occasionally a cluster of plants (umbel). The flowers, that are conspicuous and white or yellowish usually, 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 made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang up down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dry out capsule that splits (dehisces) releasing numerous black seeds.

The bulb lays dormant following the leaves and rose stem die back and has contractile root base that take it down further into the soil. The rose stem and leaves form in the bulb, to emerge the next season. Most kinds are dormant from summer time to late winter, flowering in the spring, though a few varieties are fall flowering.
