Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or red in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The amount of kinds has assorted, depending about how they are classified, thanks to similarity between hybridization and kinds. 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 origin of the name Narcissus is undiscovered, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the youth of this name who fell deeply in love with his own representation. The English word '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 middle of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders 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 ever more popular in Europe after the 16th hundred years and by the late 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as trim blossoms so when ornamental vegetation in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi produce a 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the national flower of Wales and the mark of cancer tumor charities in many countries. The looks of the untamed flowers in spring 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 light. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the bulb. The flower stem usually bears a solitary rose, but sometimes a cluster of blooms (umbel). The blooms, which are conspicuous and white or yellowish usually, both or seldom green 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 suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry contains a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant following the leaves and bloom stem die back and has contractile roots that take it down further into the soil. The bloom stem and leaves form in the light, to emerge the next season. Most types are dormant from warmer summer months to later winter, flowering in the planting season, though a few types are autumn flowering.
