Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 pink in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The number of species has varied, depending how they are categorised, scheduled to similarity between types and hybridization. The genus arose a while 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 unidentified, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the junior of this name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The species are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled in to the Far East to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as lower blooms so that as ornamental crops in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of shapes and colours. 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 treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide rose of Wales and the icon of malignancy charities in many countries. The appearance of the outrageous flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for 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 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 plant life are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the bulb. The vegetable stem usually bears a solitary rose, but sometimes a cluster of blossoms (umbel). The blossoms, which are conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers may hang up down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits contains a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant after the leaves and blossom stem die back and has contractile origins that take it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summer to overdue winter, flowering in the planting season, though a few varieties are fall months flowering.
