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 usually white or yellowish (orange or pink in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The true volume of varieties has varied, depending about how they are grouped, scheduled to similarity between varieties and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the true name Narcissus is mysterious, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of that name who fell deeply in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are local to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the ASIA to the tenth century prior. 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, nematodes and mites. 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 ever more popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as cut flowers and as ornamental plants in private and general population gardens. The long history of breeding has resulted in 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 of the family, narcissi produce 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 use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the national blossom of Wales and the sign of cancer charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The flower stem bears a solitary rose, but occasionally a cluster of blooms (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, both or seldom inexperienced sometimes, consist of 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 shaped corona. The bouquets may hang down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is placed dormant following the leaves and blossom stem die back again and has contractile origins that draw it down further in to the soil. The blossom leaves and stem form in the light bulb, to emerge the following season. Most species are dormant from summer to overdue winter, flowering in the springtime, though a few varieties are autumn flowering.
