Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or red in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten portions with around 50 species. The true range of types has assorted, depending on how they are grouped, thanks to similarity between hybridization and species. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the real name Narcissus is unfamiliar, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The species are local to meadows and woods in southern Europe and North Africa with a centre 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 before 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, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as cut bouquets as ornamental vegetation 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 an array of colours and shapes. 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in several cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the nationwide bloom of Wales and the mark of cancers charities in many countries. The looks 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 after flowering for an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as 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 occur from the bulb. The vegetable stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The blossoms, which can be conspicuous and white or yellow usually, 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 outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The flowers may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit involves a dried capsule that splits (dehisces) releasing numerous black seed products.
The bulb sits dormant following the leaves and bloom stem die again and has contractile origins that draw it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summertime to later winter, flowering in the planting season, though a few types are fall months flowering.
