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 used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or green in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with approximately 50 species. The true range of types has mixed, depending how they are categorized, due to similarity between hybridization and types. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the real name Narcissus is unknown, but it is often linked to a Greek word for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The types are local to meadows and woods in southern Europe and North Africa with a middle of variety in the Western 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 insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be 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 past due 19th century were an important commercial crop centred generally on holland. Narcissi are popular as trim bouquets so when ornamental crops in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of the family, narcissi create a 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the national rose of Wales and the image of malignancy charities in many countries. The appearance of the crazy 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. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The seed stem usually bears a solitary rose, but occasionally a cluster of bouquets (umbel). The plants, which are usually conspicuous and white or yellowish, both or hardly ever green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blooms may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and flower stem die again and has contractile root base that pull it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer season to past due winter, flowering in the springtime, though a few species are autumn flowering.
