Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with about 50 species. The amount of species has assorted, depending about how they are grouped, credited to similarity between types 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 origins of the real name Narcissus is mysterious, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own reflection. The English expression 'daffodil' is apparently 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 center of diversity in the Traditional 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 tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be 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 after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mostly on holland. Today narcissi are popular as slash plants as ornamental plants in private and general public 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 their family, narcissi produce a 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of planting season. The daffodil is the nationwide blossom of Wales and the sign of cancers charities in many countries. The appearance of the outdoors 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 next time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the light. The herb stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be usually conspicuous and white or yellowish, sometimes both or seldom green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The bouquets may hang down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry involves a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant after the leaves and blossom stem die back again and has contractile origins that draw it down further into the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most varieties are dormant from summer season to later winter, flowering in the spring and coil, though a few species are fall months flowering.
