Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or red in garden types), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The amount of kinds has assorted, depending on how they are categorised, anticipated to similarity between varieties and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the real name Narcissus is mysterious, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The varieties are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency 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 grown to be 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 past due 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slice blooms so that ornamental vegetation in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized 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 accidentally ingested. 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 fine art and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the countrywide blossom of Wales and the image of malignancy charities in many countries. The looks of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the light bulb. The flower stem bears a solitary rose, but once in a while a cluster of blooms (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, both or hardly ever renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may suspend down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit contains a dried up capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant after the leaves and blossom 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 following season. Most kinds are dormant from summer time to later winter, flowering in the spring, though a few species are fall months flowering.
