Description Narcissus poeticus 39;Recurvus39;.jpg

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 the cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden kinds), with either even or contrasting colored corona and tepals.

Narcissus were popular in historic civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with roughly 50 species. The number of varieties has varied, depending about how they are categorised, due to similarity between hybridization and species. 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 true name Narcissus is undiscovered, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.

The varieties are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented 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, disorders and diseases 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 after the 16th hundred years and by the later 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as cut bouquets and since ornamental plants in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi produce a true 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 treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the countrywide blossom of Wales and the image of cancer charities in many countries. The looks of the outrageous 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 to a underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.

The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The plant stem usually bears a solitary rose, but sometimes a cluster of bouquets (umbel). The bouquets, which are conspicuous and white or yellowish usually, sometimes both or almost never renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed 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 discover six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit contains a dried up capsule that splits (dehisces) launching numerous black seed products.

The bulb lays dormant after the leaves and blossom stem die back and has contractile roots that pull it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from warmer summer months to later winter, flowering in the spring, though a few varieties are autumn flowering.
