Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 by a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The number of species has varied, depending on how they are categorized, a consequence of to similarity between hybridization and types. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is mysterious, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some 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 hundred years and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as cut blooms so when ornamental plant life in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members of the family, narcissi produce 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of spring. The daffodil is the national blossom of Wales and the icon of tumor charities in many countries. The looks of the outrageous flowers in springtime 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 bulb. They regrow in the next year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The plant stem usually bears a solitary flower, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be usually conspicuous and white or yellow, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The flowers may suspend down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb sits dormant following the leaves and flower stem die back and has contractile roots that pull it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer months to overdue winter, flowering in the spring and coil, though a few species are fall flowering.
