Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names 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 the cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or red in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten portions with approximately 50 species. The number of species has varied, depending how they are categorized, scheduled to similarity between types and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is anonymous, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the children of that name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The types are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. 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 others 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 following the 16th century and by the late 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as slash blossoms as ornamental plants in private and open public gardens today. The long history of breeding has led to 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 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 resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of planting season. The daffodil is the national rose of Wales and the mark of cancer charities in many countries. The looks of the crazy flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the bulb. The vegetable stem bears a solitary rose, but once in a while a cluster of plants (umbel). The plants, that are conspicuous and white or yellow usually, sometimes both or almost never inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may hang up down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant following the leaves and rose stem die back and has contractile roots that pull it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from summer time to overdue winter, flowering in the spring, though a few species are fall flowering.
