Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 blooms are generally white or yellow (orange or pink in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten parts with around 50 species. The true number of types has mixed, depending about how they are labeled, scheduled to similarity between kinds and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the true name Narcissus is anonymous, but it is linked to 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 phrase 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were presented into the ASIA to the tenth hundred years 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, mites and nematodes. 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 after the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as cut bouquets so when ornamental plant life in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members with 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the nationwide rose of Wales and the sign of tumor charities in many countries. The looks of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the next time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the bulb. The flower stem bears a solitary rose, but occasionally a cluster of flowers (umbel). The flowers, which are usually conspicuous and white or yellow, both or rarely renewable sometimes, consist of 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 molded corona. The flowers may hang down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant following the leaves and bloom stem die back again and has contractile root base that take it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from warmer summer months to later winter, flowering in the springtime, though a few varieties are fall months flowering.
