Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 the cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or red in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten areas with approximately 50 species. The number of species has assorted, depending about how they are categorized, due to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the true name Narcissus is unknown, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The varieties are native to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as chop blossoms so that ornamental plants in private and general 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 shapes and colours. Like other members of these 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the national flower of Wales and the image of tumors charities in many countries. The looks of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the bulb. The vegetable stem bears a solitary bloom, but once in a while a cluster of bouquets (umbel). The plants, that happen to be usually conspicuous and white or yellowish, both or seldom green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries includes a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb is placed dormant after the leaves and rose stem die back and has contractile roots that yank it down further in to the soil. The blossom leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summertime to later winter, flowering in the spring, though a few types are autumn flowering.
