Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 by way of a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with roughly 50 species. The amount of species has mixed, depending about how they are labeled, scheduled to similarity between species and hybridization. The genus arose a while 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 undiscovered, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern Europe and North Africa with a middle of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released in to 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, 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as cut blossoms so when ornamental vegetation in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of their family, narcissi produce a true 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 within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as icons of springtime. The daffodil is the nationwide rose of Wales and the sign of cancer tumor charities in many countries. The looks of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage bulb. They regrow in the following time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light bulb. The flower stem usually bears a solitary rose, but sometimes a cluster of bouquets (umbel). The bouquets, which are usually conspicuous and white or yellowish, sometimes both or almost never green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry includes a dried out capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant after the leaves and bloom stem die again and has contractile origins that draw it down further into the soil. The bloom leaves and stem form in the light, to emerge the following season. Most varieties are dormant from summer time to overdue winter, flowering in the spring and coil, though a few species are autumn flowering.
