Narcissus /n?:r's?s?s/ is a genus of mainly 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or pink in garden types), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with about 50 species. The amount of kinds has assorted, depending about how they are categorised, scheduled to similarity between kinds and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the true name Narcissus is unfamiliar, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented in to the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as chop flowers so that as ornamental plant life in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. 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 ingested accidentally. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the countrywide rose of Wales and the icon of cancer charities in many countries. The appearance of the untamed flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the light bulb. The herb stem bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The plants, which are usually conspicuous and white or yellowish, both or rarely green sometimes, contain 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. A couple of six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries includes a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant after the leaves and flower stem die back again and has contractile origins that move it down further into the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most types are dormant from summer season to overdue winter, flowering in the springtime, though a few types are fall months flowering.
