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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or green in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten parts with roughly 50 species. The true volume of species has assorted, depending about how they are categorized, thanks to similarity between hybridization and varieties. 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 exact origins of the name Narcissus is unidentified, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created in to the ASIA to the tenth century prior. Narcissi have a tendency 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 others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as trim flowers so when ornamental plant life in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members of their family, narcissi produce 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a true number of themes in various cultures, ranging from fatality to fortune, and as icons of planting season. The daffodil is the countrywide rose of Wales and the mark of cancers charities in many countries. The looks of the outdoors flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light. They regrow in the next time from brown-skinned ovoid light bulbs 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 increase as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The flower stem bears a solitary bloom, but occasionally a cluster of blooms (umbel). The plants, which are conspicuous and white or yellowish usually, both or almost never green sometimes, 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 shaped corona. The bouquets may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant after the leaves and rose stem die again and has contractile roots that pull it down further into the soil. The rose stem and leaves form in the light, to emerge the next season. Most species are dormant from summer time to later winter, flowering in the planting season, though a few varieties are fall flowering.
