Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or green in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten portions with approximately 50 species. The true variety of varieties has assorted, depending on how they are categorized, due to similarity between hybridization and kinds. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the real name Narcissus is anonymous, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The varieties are local to meadows and woods in southern Europe 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 released in to 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as lower blossoms and as ornamental vegetation in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members of their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal used 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 number of themes in different cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the national blossom of Wales and the mark of malignancy charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the bulb. The flower stem bears a solitary flower, but occasionally a cluster of blossoms (umbel). The flowers, that happen to be usually conspicuous and white or yellow, both or seldom green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry consists of a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant after the leaves and bloom stem die back and has contractile roots that take it down further into the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most types are dormant from summertime to late winter, flowering in the springtime, though a few species are autumn flowering.
