Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten areas with roughly 50 species. The true quantity of species has assorted, depending on how they are labeled, scheduled to similarity between species and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the true name Narcissus is unidentified, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern Europe and North Africa with a middle of diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency 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 others 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 overdue 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as chop bouquets as ornamental plant life in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the mark of malignancy charities in many countries. The looks 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 bulb. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels 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 grow as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The flower stem usually bears a solitary flower, but occasionally a cluster of bouquets (umbel). The blossoms, that are conspicuous and white or yellowish usually, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The bouquets may hang up down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant following the leaves and bloom stem die again and has contractile root base that take it down further into the soil. The blossom leaves and stem form in the light, to emerge the next season. Most types are dormant from summer time to later winter, flowering in the planting season, though a few varieties are fall months flowering.
