Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or red in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with about 50 species. The true variety of varieties has mixed, depending about how they are labeled, due to similarity between hybridization and varieties. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is unknown, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases 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 earliest times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as trim blooms so that as ornamental crops in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi create a 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the sign of cancer charities in many countries. The looks of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage bulb. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the light bulb. The place stem bears a solitary rose, but sometimes a cluster of bouquets (umbel). The bouquets, which are usually conspicuous and white or yellow, both or seldom inexperienced 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 plants may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant following the leaves and flower stem die back and has contractile roots that pull it down further in to the soil. The bloom leaves and stem form in the light, to emerge the following season. Most varieties are dormant from summer months to later winter, flowering in the spring and coil, though a few types are fall months flowering.
