Narcissus /n?:r's?s?s/ is a genus of mostly 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 a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or red in garden kinds), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally described by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with roughly 50 species. The true quantity of species has assorted, depending on how they are categorised, thanks to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is anonymous, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a middle of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were launched in to the ASIA to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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 mostly on the Netherlands. Today narcissi are popular as chop blossoms as ornamental vegetation in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of their 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in different cultures, ranging from fatality to good fortune, and as icons of planting season. The daffodil is the countrywide rose of Wales and the icon of cancer tumor charities in many countries. The appearance of the outrageous flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light bulb. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the bulb. The herb stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The blossoms, which can be conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, 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 disc to conical formed corona. The blossoms may hang 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 fruit contains a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant following the leaves and bloom stem die again and has contractile root base that draw it down further in to the soil. The flower stem and leaves form in the light, to emerge the next season. Most types are dormant from summer months to past due winter, flowering in the planting season, though a few varieties are fall months flowering.
