Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or pink in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with approximately 50 species. The true range of species has mixed, depending about how they are categorised, credited to similarity between species 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 origins of the name Narcissus is unfamiliar, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were presented into the ASIA 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, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slice bouquets so when ornamental plant life in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi create 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 treatment of Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the national rose of Wales and the icon of cancer tumor charities in many countries. The appearance of the outrageous flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light. They regrow in the following 12 months 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 level of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the light bulb. The place stem bears a solitary flower, but sometimes a cluster of flowers (umbel). The plants, which can be conspicuous and white or yellowish usually, both or seldom 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 made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The plants may suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant after the leaves and flower stem die back again and has contractile origins that move it down further in to the soil. The rose leaves and stem form in the light, to emerge the following season. Most species are dormant from summer time to late winter, flowering in the springtime, though a few species are autumn flowering.
