Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The true variety of kinds has assorted, depending on how they are classified, anticipated to similarity between kinds and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is unknown, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into 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, 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 ever more popular in Europe following the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as trim blossoms so that as ornamental plants in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members with their 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the national blossom of Wales and the sign of tumor charities in many countries. The looks of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the next 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light bulb. The flower stem bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The flowers, which are usually conspicuous and white or yellow, sometimes both or seldom renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk 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 poor (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and rose stem die back and has contractile roots that move it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer to late winter, flowering in the planting season, though a few types are fall flowering.
