Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants 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 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 usually white or yellowish (orange or green in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten sections with approximately 50 species. The number of species has varied, depending about how they are labeled, due to similarity between types and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the name Narcissus is unidentified, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own representation. The English term 'daffodil' appears to be derived 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 diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into 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, 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 initial 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 mainly on the Netherlands. Today narcissi are popular as slash bouquets so that as ornamental plant life in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi produce a true 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 within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in various cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the national bloom of Wales and the mark of cancer tumor charities in many countries. The looks of the outrageous flowers in spring is associated with celebrations 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 calendar year from brown-skinned ovoid lights 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 high as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the light. The place stem usually bears a solitary blossom, but once in a while a cluster of blooms (umbel). The plants, which are conspicuous and white or yellow usually, sometimes both or rarely renewable, contain 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 disc to conical shaped corona. The plants may suspend down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries involves a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant following the leaves and blossom stem die back again and has contractile root base that pull it down further into the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer season to past due winter, flowering in the spring and coil, though a few types are fall flowering.
