Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 by a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or red in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten sections with approximately 50 species. The true quantity of kinds has mixed, depending about how they are grouped, due to similarity between hybridization and varieties. 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 origin of the name Narcissus is undiscovered, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as slice blooms as ornamental plants in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi create 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 use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the sign of malignancy charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for 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 the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the bulb. The plant stem bears a solitary flower, but once in a while a cluster of bouquets (umbel). The blossoms, that are usually conspicuous and white or yellowish, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may hang down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lays dormant after the leaves and blossom stem die again and has contractile roots that draw it down further in to the soil. The blossom stem and leaves form in the light, to emerge the next season. Most types are dormant from summer season to past due winter, flowering in the spring and coil, though a few varieties are fall flowering.
