Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 blossoms are usually white or yellow (orange or green in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten areas with roughly 50 species. The amount of species has varied, depending on how they are grouped, as a consequence 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 precise origin of the name Narcissus is unidentified, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species are local to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented into the Far East 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 some 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 late 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as chop blooms as ornamental vegetation in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the mark of cancer charities in many countries. The appearance of the crazy flowers in spring is associated with festivals 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 following season 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 height of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the bulb. The vegetable stem usually bears a solitary flower, but sometimes a cluster of plants (umbel). The flowers, that happen to be conspicuous and white or yellow usually, sometimes both or hardly ever green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is placed dormant after the leaves and blossom stem die back again and has contractile origins that draw it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most kinds are dormant from summer months to late winter, flowering in the spring and coil, though a few species are autumn flowering.
