Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names 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 a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or pink in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten parts with around 50 species. The number of species has varied, depending on how they are labeled, as a consequence to similarity between hybridization and types. The genus arose some right 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 unfamiliar, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of this 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 types are indigenous to meadows and woods in southern European countries and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slash blooms as ornamental vegetation in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. Like other members with their 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, 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 flower of Wales and the sign of malignancy charities in many countries. The looks of the wild flowers in springtime is associated with festivals 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 light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the bulb. The herb stem bears a solitary bloom, but occasionally a cluster of bouquets (umbel). The bouquets, which are usually conspicuous and white or yellow, sometimes both or hardly ever green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may hang up down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit involves a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant after the leaves and flower stem die back again and has contractile root base that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most types are dormant from summer time to late winter, flowering in the spring, though a few species are fall months flowering.
