Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands 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 flowers are usually white or yellowish (orange or red in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten portions with about 50 species. The number of kinds has mixed, depending on how they are labeled, due to similarity between kinds and hybridization. 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 exact origin of the name Narcissus is unfamiliar, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The varieties are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the European 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 others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the late 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as slice flowers and since ornamental plants in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members with 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 in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the image of tumor charities in many countries. The looks of the crazy flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light bulb. The place stem bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The blooms, that are usually conspicuous and white or yellow, sometimes both or seldom renewable, 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 disc to conical shaped corona. The plants may hang up down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry contains a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant after the leaves and rose stem die back and has contractile root base that pull it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer time to overdue winter, flowering in the planting season, though a few types are fall flowering.
