Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 standard or contrasting colored tepals and corona.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The true volume of species has varied, depending about how they are categorised, thanks to similarity between hybridization and kinds. 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 anonymous, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are native to meadows and woods in southern Europe and North Africa with a centre 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others 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 century were an important commercial crop centred mainly on holland. Narcissi are popular as chop bouquets as ornamental plants in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. 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 within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as symbols of spring. The daffodil is the nationwide bloom of Wales and the image of cancer charities in many countries. The appearance of the untamed flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the light. The seed stem usually bears a solitary rose, but sometimes a cluster of flowers (umbel). The blossoms, which can be usually conspicuous and white or yellow, sometimes both or hardly ever inexperienced, 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 disk to conical designed corona. The blossoms may hang down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb sits dormant following the leaves and bloom stem die again and has contractile origins that draw it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most kinds are dormant from summer months to overdue winter, flowering in the spring, though a few varieties are fall months flowering.
