Narcissus /n?:r's?s?s/ is a genus of mainly 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 a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or pink in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true number of varieties has assorted, depending on how they are labeled, credited to similarity between species 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 source of the real name Narcissus is mysterious, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as lower flowers so when ornamental vegetation in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of shapes and colours. Like other members with 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 death to fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the mark of tumor charities in many countries. The appearance of the outdoors flowers in springtime is associated with festivals 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 types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the light. The seed stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The plants, that are usually conspicuous and white or yellow, both or almost never renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blossoms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and rose stem die back and has contractile roots that draw it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the following season. Most types are dormant from summer season to late winter, flowering in the spring, though a few species are fall months flowering.
