Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 blooms are usually white or yellow (orange or green in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The true range of varieties has mixed, depending about how they are labeled, credited to similarity between types and hybridization. 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 origin of the name Narcissus is unidentified, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own reflection. The English word 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop plants so that as ornamental plant life in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range 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 ingested unintentionally. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the countrywide rose of Wales and the symbol of malignancy charities in many countries. The looks of the outrageous flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage light bulb. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the light. The place stem usually bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The flowers, that are 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 outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blooms may suspend down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit consists of a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant following the leaves and blossom stem die back and has contractile roots that draw it down further into the soil. The rose stem and leaves form in the bulb, to emerge the next season. Most kinds are dormant from summer to late winter, flowering in the planting season, though a few varieties are fall months flowering.
