Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 yellowish (orange or red in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The number of varieties has assorted, depending about how they are classified, due to similarity between hybridization and species. 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 origin of the true name Narcissus is anonymous, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. 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 grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as lower blooms and since ornamental plant life 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 categorised into divisions, covering a variety of colours and shapes. Like other members with their family, narcissi produce a 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 use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the nationwide blossom of Wales and the mark of malignancy charities in many countries. The appearance of the outdoors flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light. The seed stem usually bears a solitary flower, but occasionally a cluster of blooms (umbel). The plants, which can be usually conspicuous and white or yellow, both or seldom renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant after the leaves and rose stem die back again and has contractile roots that pull it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from summer time to late winter, flowering in the springtime, though a few species are fall months flowering.
