Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation 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 with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten parts with about 50 species. The amount of types has mixed, depending how they are labeled, 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 areas of southwest Europe. The precise origin of the name Narcissus is undiscovered, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the Western 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 have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some 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 century and by the later 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slice blooms so when ornamental vegetation in private and general population gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi produce 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the national rose of Wales and the image of malignancy charities in many countries. The looks of the outrageous flowers in spring and coil 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. They regrow in the following time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light. The place stem bears a solitary blossom, but sometimes a cluster of blooms (umbel). The blossoms, which can be usually conspicuous and white or yellowish, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang up down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit involves a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant after the leaves and blossom stem die back and has contractile origins that move it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the following season. Most species are dormant from summertime to past due winter, flowering in the planting season, though a few types are fall months flowering.
