Narcissus tazetta, Nhu Nguyen

Narcissus /n?:r's?s?s/ is a genus of predominantly 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 by the cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or green in garden types), with either uniform or contrasting colored corona and tepals.

Narcissus were well known in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten portions with about 50 species. The true volume of types has mixed, depending how they are categorised, due to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the true name Narcissus is unfamiliar, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The varieties are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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 tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as slice blooms and since ornamental plant life in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the nationwide bloom of Wales and the mark of malignancy charities in many countries. The appearance of the wild flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the following yr from brown-skinned ovoid light 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 grow as extra tall as 80 cm.

The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the bulb. The seed stem usually bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The flowers, that are usually conspicuous and white or yellow, sometimes both or almost never renewable, contain 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 disk to conical shaped corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry includes a dried capsule that splits (dehisces) releasing numerous black seeds.

The bulb lies dormant after the leaves and bloom stem die again and has contractile root base that draw it down further into the soil. The bloom leaves and stem form in the light, to emerge the following season. Most species are dormant from summer time to overdue winter, flowering in the springtime, though a few species are fall flowering.
