Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 by a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten areas with around 50 species. The number of types has varied, depending about how they are labeled, credited 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 exact origin of the true name Narcissus is unfamiliar, but it is associated with a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of that name who fell deeply in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The types are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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 become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower blossoms so that 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 a variety of shapes and colours. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. 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 art work and literature, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as symbols of spring and coil. The daffodil is the nationwide bloom of Wales and the mark of tumor charities in many countries. The appearance of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid light 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 height of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light bulb. The flower stem bears a solitary rose, but sometimes a cluster of blooms (umbel). The blossoms, that are usually conspicuous and white or yellow, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries involves a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant after the leaves and bloom stem die again and has contractile root base that take it down further in to the soil. The rose stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer months to past due winter, flowering in the spring and coil, though a few species are fall months flowering.
