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 with a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden types), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten sections with around 50 species. The true quantity of varieties has assorted, depending on how they are categorised, due to similarity between types and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is undiscovered, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched in to the Far East to the tenth hundred years 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 become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as chop flowers and as ornamental crops in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the countrywide bloom of Wales and the sign of tumor charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with festivals 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 following yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The crops are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the bulb. The seed stem usually bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The blossoms, which are conspicuous and white or yellowish usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms 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 fruit includes a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and bloom stem die again and has contractile roots that take it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most varieties are dormant from summer time to late winter, flowering in the spring, though a few species are fall months flowering.
