Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 by a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or red in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with about 50 species. The amount of types has assorted, depending how they are grouped, due to similarity between hybridization and varieties. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the name Narcissus is mysterious, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the young ones of this name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The types are native to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched in to the Far East to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders 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 initial times, but became increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred generally on holland. Narcissi are popular as trim bouquets as ornamental crops in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of their family, narcissi produce a 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 treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the national flower of Wales and the mark of cancer tumor charities in many countries. The looks of the outdoors flowers in spring and coil is associated with festivals 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 next time from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the bulb. The vegetable stem usually bears a solitary bloom, but sometimes a cluster of blossoms (umbel). The blossoms, that happen to be usually conspicuous and white or yellow, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant after the leaves and blossom stem die again and has contractile root base that move it down further in to the soil. The bloom stem and leaves form in the light, to emerge the following season. Most kinds are dormant from summer months to overdue winter, flowering in the spring, though a few species are fall flowering.
