Narcissus /n?:r's?s?s/ is a genus of predominantly 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with roughly 50 species. The true number of types has mixed, depending about how they are categorized, anticipated to similarity between varieties and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the true name Narcissus is anonymous, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 ever more popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as slash plants as ornamental plants in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi produce a true 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 use in traditional healing and has led to 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 different cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the nationwide bloom of Wales and the symbol of cancer charities in many countries. The looks of the wild 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 an underground storage light. They regrow in the following calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the bulb. The place stem bears a solitary flower, but occasionally a cluster of plants (umbel). The plants, that happen to be conspicuous and white or yellowish usually, both or hardly ever green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may hang down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries contains a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is placed dormant following the leaves and rose stem die back again and has contractile root base that pull it down further in to the soil. The blossom stem and leaves form in the light, to emerge the following season. Most types are dormant from summer season to later winter, flowering in the springtime, though a few species are fall flowering.
