Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or green in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten sections with about 50 species. The true volume of kinds has varied, depending about how they are grouped, due to similarity between hybridization and kinds. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the true name Narcissus is unfamiliar, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend 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 grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as chop plants so when ornamental plant life in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members of their 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the countrywide blossom of Wales and the image of cancer tumor charities in many countries. The appearance of the wild flowers in spring 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 year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The flower stem bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The flowers, which can be usually conspicuous and white or yellowish, sometimes both or seldom inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits contains a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant following the leaves and flower stem die back and has contractile roots that pull it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer season to later winter, flowering in the planting season, though a few types are autumn flowering.
