Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 flowers are generally white or yellow (orange or pink in garden types), with either even or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The number of species has varied, depending how they are categorised, thanks to similarity between hybridization and types. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the true name Narcissus is unfamiliar, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created into the Far East to the tenth hundred years prior. 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 become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as lower blooms and since ornamental crops in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized 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 ingested inadvertently. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the image of cancer tumor charities in many countries. The looks of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the next calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels 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 develop as high as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the bulb. The place stem usually bears a solitary rose, but sometimes a cluster of flowers (umbel). The flowers, which can be usually conspicuous and white or yellow, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries consists of a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and flower stem die back again and has contractile origins that pull 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 summertime to past due winter, flowering in the spring and coil, though a few varieties are autumn flowering.
