Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or red in garden types), with either even or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The amount of types has varied, depending how they are categorized, credited to similarity between kinds and hybridization. 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 precise origins of the name Narcissus is unfamiliar, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the young ones of this name who fell deeply in love with his own representation. The English term 'daffodil' appears to be produced 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 centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the late 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as cut flowers and since ornamental crops in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi create 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 used in 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 number of themes in several cultures, ranging from death to fortune, and as icons of spring. The daffodil is the nationwide flower of Wales and the mark of cancer tumor charities in many countries. The appearance of the wild flowers in planting season 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. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the light. The herb stem usually bears a solitary flower, but sometimes a cluster of blooms (umbel). The bouquets, which can be conspicuous and white or yellowish usually, both or rarely green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits contains a dried capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant following the leaves and flower stem die back and has contractile origins that take it down further in to the soil. The bloom leaves and stem form in the light, to emerge the following season. Most varieties are dormant from summertime to later winter, flowering in the planting season, though a few varieties are autumn flowering.
