Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or green in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The amount of kinds has assorted, depending on how they are categorized, a consequence of to similarity between hybridization and kinds. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the true name Narcissus is undiscovered, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the youngsters of this name who fell deeply in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The varieties are native to meadows and woods in southern European countries and North Africa with a middle of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi tend 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, 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 increasingly popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slash plants and since ornamental crops in private and general population gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of shapes and colours. Like other members of their 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide bloom of Wales and the image of cancer tumor charities in many countries. The looks of the outdoors flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the bulb. The herb stem usually bears a solitary rose, but once in a while a cluster of blossoms (umbel). The flowers, which can be conspicuous and white or yellow usually, sometimes both or hardly ever green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blossoms may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lays dormant following the leaves and rose stem die back and has contractile origins that draw it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer to overdue winter, flowering in the spring and coil, though a few types are fall flowering.
