Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands 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 green in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten parts with approximately 50 species. The true quantity of species has assorted, depending how they are classified, 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 regions of southwest Europe. The precise origin of the name Narcissus is mysterious, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The types are indigenous to meadows and woods in southern Europe and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. 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 insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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. Today narcissi are popular as slash blooms so when ornamental plant life in private and general public gardens. The long history of breeding has resulted in a large number 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 create 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 use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide rose of Wales and the mark of cancer charities in many countries. The appearance of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light bulb. They regrow in the following time from brown-skinned ovoid lights 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 grow as large as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the light bulb. The place stem bears a solitary bloom, but sometimes a cluster of flowers (umbel). The blooms, which can be conspicuous and white or yellow 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 exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry involves a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and flower stem die back and has contractile roots that yank it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summertime to late winter, flowering in the spring, though a few kinds are fall flowering.
