Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 yellowish (orange or green in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with approximately 50 species. The true volume of varieties has varied, depending how they are categorized, credited to similarity between species and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is unknown, but it is linked to 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 word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East to the tenth century prior. Narcissi tend 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 become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower bouquets so that ornamental crops in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide flower of Wales and the symbol of cancers charities in many countries. The looks of the crazy flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light bulb. They regrow in the next 12 months from brown-skinned ovoid lights 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 increase as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the bulb. The place stem usually bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The blooms, which can be conspicuous and white or yellow usually, both or almost never green sometimes, 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 designed corona. The plants may hang down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant after the leaves and flower stem die back again and has contractile roots that draw it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from warmer summer months to late winter, flowering in the planting season, though a few varieties are fall months flowering.
