Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 blooms are usually white or yellow (orange or red in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The number of types has assorted, depending about how they are categorised, thanks to similarity between hybridization and kinds. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the true name Narcissus is unknown, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled into the Far East to the tenth century 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 others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred generally on holland. Narcissi are popular as chop blossoms and as ornamental crops in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the nationwide bloom of Wales and the sign of cancer charities in many countries. The appearance of the outdoors flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as tall as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves occur from the light. The vegetable stem bears a solitary flower, but occasionally a cluster of bouquets (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, sometimes both or rarely renewable, 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 disk to conical shaped corona. The flowers may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry consists of a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and flower stem die back again and has contractile roots that take it down further in to the soil. The bloom leaves and stem form in the light, to emerge the next season. Most species are dormant from warmer summer months to past due winter, flowering in the spring, though a few species are autumn flowering.
