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 being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or red in garden varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten areas with approximately 50 species. The amount of varieties has mixed, depending how they are categorised, scheduled 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 precise origins of the name Narcissus is undiscovered, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The varieties are native to meadows and woods in southern European countries and North Africa with a middle of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild 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 become 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 century and by the past due 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as slash blooms and as ornamental plants in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of shapes and colours. Like other members with their family, narcissi create 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 art and books, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as icons of planting season. The daffodil is the nationwide flower of Wales and the symbol of cancers charities in many countries. The looks of the crazy flowers in spring and coil 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 following yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the bulb. The vegetable stem usually bears a solitary flower, but once in a while a cluster of blooms (umbel). The blossoms, that are usually conspicuous and white or yellowish, sometimes both or almost never inexperienced, consist of 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 disk to conical molded corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry involves a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant after the leaves and flower stem die again and has contractile roots that take it down further into the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most varieties are dormant from summer to overdue winter, flowering in the spring and coil, though a few kinds are autumn flowering.
