Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or pink in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten areas with around 50 species. The true variety of types has mixed, depending about how they are grouped, credited 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 origins of the name Narcissus is mysterious, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created in to the Far East to the tenth hundred years prior. Narcissi have a tendency 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, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as cut blooms as ornamental crops in private and general public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of their 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in different cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the mark of malignancy charities in many countries. The appearance of the outdoors flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach levels 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 may grow as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The vegetable stem bears a solitary bloom, but once in a while a cluster of bouquets (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 pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry involves a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant after the leaves and rose stem die again and has contractile roots that yank it down further in to the soil. The rose stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summer season to later winter, flowering in the springtime, though a few varieties are fall flowering.
