Narcissus /n?:r's?s?s/ is a genus of mostly 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 by a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten portions with approximately 50 species. The number of species has varied, depending on how they are classified, anticipated to similarity between kinds and hybridization. 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 unfamiliar, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The types are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East 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, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as cut bouquets so when ornamental crops in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members of the family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 skill and literature, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the nationwide rose of Wales and the mark of cancer charities in many countries. The looks of the crazy flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage bulb. They regrow in the following calendar year from brown-skinned ovoid bulbs 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 develop as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the light. The seed stem bears a solitary rose, but occasionally a cluster of plants (umbel). The flowers, that are conspicuous and white or yellowish usually, both or hardly ever inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry involves a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant following the leaves and flower stem die back and has contractile root base that draw it down further in to the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most species are dormant from warmer summer months to later winter, flowering in the spring, though a few types are fall flowering.
