Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names 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 blooms are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten sections with approximately 50 species. The true variety of varieties has mixed, depending how they are categorised, credited to similarity between species and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is mysterious, but it is often linked to a Greek word for intoxicated (narcotic) and the misconception 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 compared commonly.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western 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 tend 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, mites and nematodes. 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 ever more popular in Europe after the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as cut bouquets so when ornamental plants in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. 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 use in 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 various cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the sign of tumor charities in many countries. The looks of the outrageous flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage light. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the light. The vegetable stem bears a solitary flower, but occasionally a cluster of blooms (umbel). The bouquets, which can be conspicuous and white or yellow usually, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang up down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is placed dormant following the leaves and flower stem die again and has contractile roots that pull it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summer months to past due winter, flowering in the spring, though a few varieties are fall months flowering.
