Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or green in garden types), with either even or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with approximately 50 species. The number of varieties has varied, depending on how they are categorized, a consequence of to similarity between hybridization and kinds. 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 exact source of the true name Narcissus is unidentified, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi have a tendency 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 some are threatened by increasing tourism and urbanisation.
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 later 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower blooms and since ornamental vegetation in private and open public gardens today. The long history of breeding has led to 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 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 use within 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 true number of themes in several cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the nationwide rose of Wales and the image of cancer charities in many countries. The appearance of the untamed flowers in springtime is associated with festivals 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 following season 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 may grow as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the light. The vegetable stem bears a solitary bloom, but once in a while a cluster of flowers (umbel). The blooms, which can be conspicuous and white or yellowish usually, both or seldom green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may hang up down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits contains a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is placed dormant following the leaves and bloom stem die back and has contractile root base that move it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summertime to overdue winter, flowering in the planting season, though a few kinds are fall flowering.
