Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 usually white or yellow (orange or green in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten areas with roughly 50 species. The true amount of kinds has assorted, depending about how they are classified, due 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 precise source of the true name Narcissus is unknown, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the young ones of that name who fell deeply in love with his own reflection. The English expression '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 center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released into 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 become extinct, while others are threatened by increasing urbanisation and tourism.
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 mainly on the Netherlands. Narcissi are popular as slice bouquets and since ornamental crops in private and general public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members of these 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 books and art work, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as symbols of springtime. The daffodil is the countrywide blossom of Wales and the image of malignancy charities in many countries. The looks of the outrageous 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 for an underground storage light. They regrow in the next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the bulb. The vegetable stem bears a solitary bloom, but occasionally a cluster of bouquets (umbel). The flowers, which can be usually conspicuous and white or yellowish, sometimes both or seldom green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The super fruit involves a dried out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant after the leaves and bloom stem die back again and has contractile origins that pull it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the following season. Most species are dormant from summertime to overdue winter, flowering in the spring, though a few species are autumn flowering.
