Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or pink in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with around 50 species. The amount of types has assorted, depending about how they are grouped, due to similarity between varieties 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 source of the true name Narcissus is anonymous, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The varieties are native to meadows and woods in southern European countries and North Africa with a center of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. 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 increasingly popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as trim blooms so that as ornamental crops in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi produce a true 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 in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the national bloom of Wales and the mark of cancer tumor charities in many countries. The appearance of the wild flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light bulb. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the bulb. The flower stem usually bears a solitary rose, but occasionally a cluster of flowers (umbel). The blooms, that are usually conspicuous and white or yellow, sometimes both or hardly ever green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior 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. A couple of six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant following the leaves and flower stem die back again and has contractile roots that take it down further into the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summer to late winter, flowering in the springtime, though a few kinds are autumn flowering.
