Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles 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 blossoms are usually white or yellowish (orange or red in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten sections with approximately 50 species. The true quantity of species has assorted, depending on how they are grouped, as a consequence to similarity between hybridization and varieties. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the name Narcissus is undiscovered, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English term 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The types are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released into 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, 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 earliest times, but became ever more popular in Europe following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as trim flowers as ornamental plant life in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of 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 led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the countrywide bloom of Wales and the sign of tumors charities in many countries. The appearance of the crazy flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the bulb. The flower stem usually bears a solitary bloom, but occasionally a cluster of bouquets (umbel). The blooms, that happen to be conspicuous and white or yellowish usually, both or seldom inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries involves a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and flower stem die again and has contractile root base that move it down further in to the soil. The rose stem and leaves form in the light, to emerge the following season. Most kinds are dormant from summer months to late winter, flowering in the planting season, though a few species are fall flowering.
