Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 by a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or green in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten sections with about 50 species. The true range of kinds has varied, depending how they are categorized, due to similarity between species and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the real name Narcissus is mysterious, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the children of this name who fell deeply in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into 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, nematodes and mites. Some Narcissus species have grown to be extinct, while others 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 century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as trim blooms and as ornamental plant life in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array 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 in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of springtime. The daffodil is the nationwide flower of Wales and the mark of tumors charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light. The vegetable stem bears a solitary bloom, but once in a while a cluster of plants (umbel). The blossoms, which can be conspicuous and white or yellow usually, sometimes both or almost never green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The plants may hang down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is placed dormant after the leaves and blossom stem die back again and has contractile roots that draw it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summer time to overdue winter, flowering in the springtime, though a few types are fall months flowering.
