Narcissus /n?:r's?s?s/ is a genus of mainly 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 by way of a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or pink in garden kinds), with either uniform or contrasting colored tepals and corona.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten sections with about 50 species. The true volume of species has varied, depending how they are classified, thanks to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the real name Narcissus is unfamiliar, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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, 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 earliest times, but became ever more popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred generally on holland. Narcissi are popular as slash flowers as ornamental vegetation in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in various cultures, ranging from death to fortune, and as icons of spring and coil. The daffodil is the nationwide rose of Wales and the symbol of tumors charities in many countries. The looks of the outrageous flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light. They regrow in the next 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 height of 5-8 cm, while Narcissus tazetta might grow as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the bulb. The place stem bears a solitary rose, but occasionally a cluster of bouquets (umbel). The plants, which are usually conspicuous and white or yellowish, both or hardly ever renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb is placed dormant following the leaves and bloom stem die again and has contractile origins that yank it down further into the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from summer months to past due winter, flowering in the spring and coil, though a few types are fall flowering.
