Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 flowers are usually white or yellowish (orange or pink in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The amount of species has assorted, depending on how they are labeled, due to similarity between types 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 exact source of the name Narcissus is undiscovered, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The varieties are native to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases 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 earliest times, but became ever more popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as slash blossoms and as ornamental plants in private and general public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. Like other members of the family, narcissi create 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as symbols of springtime. The daffodil is the nationwide blossom of Wales and the mark of malignancy charities in many countries. The looks of the wild flowers in springtime is associated with celebrations 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 regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The flower stem bears a solitary rose, but occasionally a cluster of bouquets (umbel). The plants, that happen to be usually conspicuous and white or yellow, sometimes both or hardly ever inexperienced, consist of 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 disc to conical formed corona. The bouquets may hang up down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries includes a dry capsule that splits (dehisces) releasing numerous black seed products.
The bulb sits dormant following the leaves and rose stem die again and has contractile roots that move it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summertime to overdue winter, flowering in the springtime, though a few varieties are autumn flowering.
