Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or green in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with about 50 species. The true amount of kinds has mixed, depending about how they are classified, a consequence of to similarity between hybridization and species. 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 name Narcissus is mysterious, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The types are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched in to the ASIA 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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 increasingly popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as trim blooms so that ornamental crops in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members with their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the nationwide flower of Wales and the icon of tumor charities in many countries. The looks of the untamed flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the bulb. The plant stem usually bears a solitary flower, but occasionally a cluster of blooms (umbel). The plants, which can be conspicuous and white or yellowish usually, both or hardly ever renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The bouquets may hang down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit involves a dried out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant after the leaves and blossom stem die back again and has contractile roots that pull it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer months to late winter, flowering in the spring and coil, though a few species are fall months flowering.
