Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or green in garden types), with either even or contrasting colored corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten sections with about 50 species. The number of types has varied, depending on how they are grouped, anticipated to similarity between varieties 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 source of the true name Narcissus is undiscovered, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The varieties are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional 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 tend 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 tourism and urbanisation.
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 overdue 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as chop flowers and as ornamental vegetation in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled 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 ingested accidentally. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the nationwide flower of Wales and the image of cancer tumor charities in many countries. The appearance of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the bulb. The place stem usually bears a solitary blossom, but sometimes a cluster of plants (umbel). The blossoms, that happen to be usually conspicuous and white or yellowish, sometimes both or seldom renewable, 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 suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant following the leaves and bloom stem die back again and has contractile roots that yank it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer months to late winter, flowering in the springtime, though a few kinds are autumn flowering.
