Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles 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 by way of a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or green in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with approximately 50 species. The number of kinds has varied, depending how they are classified, thanks to similarity between hybridization and types. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the real name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern Europe and North Africa with a center of variety in the American 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 have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as chop flowers and as ornamental plants in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of shapes and colours. Like other members of their 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as icons of planting season. The daffodil is the national blossom of Wales and the image of tumors charities in many countries. The looks of the wild flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light. They regrow in the next season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the bulb. The herb stem usually bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The blossoms, which are usually conspicuous and white or yellowish, both or hardly ever renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may hang up down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb lays dormant after the leaves and rose stem die back and has contractile origins that move it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer months to overdue winter, flowering in the spring and coil, though a few kinds are autumn flowering.
