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 with a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or red in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The amount of varieties has assorted, depending about how they are classified, scheduled to similarity between types and hybridization. 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 origin of the real name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the junior of this name who fell deeply in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The types are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the Far East 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, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as cut bouquets and as ornamental plant life in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi create a true 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 books and artwork, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide flower of Wales and the icon of malignancy charities in many countries. The looks of the outrageous flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light bulb. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum elevation 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 blue-green or green, small, strap-shaped leaves come up from the light bulb. The plant stem usually bears a solitary rose, but sometimes a cluster of bouquets (umbel). The bouquets, which are conspicuous and white or yellowish usually, both or seldom green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry includes a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant following the leaves and bloom stem die back again and has contractile roots that move it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summertime to later winter, flowering in the springtime, though a few varieties are autumn flowering.
