Narcissus /n?:r's?s?s/ is a genus of mostly 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 plants are usually white or yellow (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The true number of varieties has assorted, depending about how they are grouped, anticipated to similarity between types and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is unidentified, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English expression 'daffodil' is apparently 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 middle of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled in to the Far East to the tenth hundred years prior. 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, nematodes and mites. Some Narcissus species have become 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 later 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as chop blossoms and as ornamental crops in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the mark of cancer tumor charities in many countries. The looks of the untamed 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 to an underground storage light. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light bulb. The place stem bears a solitary bloom, but sometimes a cluster of blooms (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or rarely green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blooms may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry involves a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is placed dormant following the leaves and blossom stem die again and has contractile root base that draw it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summertime to later winter, flowering in the planting season, though a few varieties are fall months flowering.
