Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 the cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or red in garden types), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The true volume of varieties has varied, depending how they are labeled, as a consequence to similarity between hybridization and kinds. 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 often linked to a Greek expression for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were created in to 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, 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 initial times, but became ever more popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slice blooms as ornamental vegetation in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members of their 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the national flower of Wales and the sign of cancers charities in many countries. The appearance of the wild flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as tall 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 happen from the bulb. The herb stem bears a solitary flower, but occasionally a cluster of blossoms (umbel). The bouquets, which are conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The flowers may suspend down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant after the leaves and bloom stem die back again and has contractile root base that take it down further into the soil. The rose leaves and stem form in the light, to emerge the next season. Most varieties are dormant from summer to overdue winter, flowering in the spring, though a few species are fall months flowering.
