Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or red in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The true variety of types has varied, depending how they are categorised, credited to similarity between varieties and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is unfamiliar, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The varieties are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created into 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, 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 after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as slice flowers so when ornamental crops in private and general public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members of the 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 treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring. The daffodil is the nationwide rose of Wales and the sign of malignancy charities in many countries. The looks of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light. The seed stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The blossoms, that are usually conspicuous and white or yellowish, sometimes both or seldom renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruit involves a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant after the leaves and blossom stem die again and has contractile origins that take it down further into the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer time to later winter, flowering in the spring and coil, though a few types are fall flowering.
