Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 blooms are generally white or yellow (orange or green in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The true number of kinds has assorted, depending on how they are classified, credited to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is mysterious, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of this name who fell deeply in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented into the Far East to the tenth hundred years prior. Narcissi tend 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 become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as chop blossoms as ornamental plant life in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. Like other members of the 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the national rose of Wales and the mark of cancer charities in many countries. The looks of the outdoors flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage bulb. They regrow in the following season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the light bulb. The flower stem usually bears a solitary bloom, but once in a while a cluster of bouquets (umbel). The blooms, which are conspicuous and white or yellowish usually, both or hardly ever inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb sits dormant after the leaves and blossom stem die back again and has contractile root base that yank it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer season to past due winter, flowering in the spring, though a few varieties are fall flowering.
