Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 blossoms are generally white or yellow (orange or pink in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with approximately 50 species. The amount of species has assorted, depending about how they are grouped, anticipated to similarity between types and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the name Narcissus is unknown, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of that name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The varieties are native to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. 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 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 some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as slash blossoms and as ornamental plant life in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi produce 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as symbols of spring and coil. The daffodil is the nationwide flower of Wales and the mark of tumor charities in many countries. The appearance of the crazy flowers in springtime is associated with festivals 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 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light bulb. The flower stem bears a solitary rose, but sometimes a cluster of plants (umbel). The flowers, which are usually conspicuous and white or yellow, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The bouquets may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berries involves a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and flower stem die back again and has contractile origins that move it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most species are dormant from summer time to past due winter, flowering in the planting season, though a few species are autumn flowering.
