Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or red in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with about 50 species. The true volume of varieties has assorted, depending on how they are labeled, due to similarity between hybridization and varieties. 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 exact origin of the name Narcissus is mysterious, but it is often linked to a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The varieties are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the Far East to the tenth century 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, 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 earliest times, but became increasingly popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as slice bouquets as ornamental vegetation in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of shapes and colours. 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 accidentally ingested. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the countrywide blossom of Wales and the mark of cancer tumor charities in many countries. The looks of the untamed flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the bulb. The seed stem bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The flowers, that are usually conspicuous and white or yellow, both or almost never green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is placed dormant after the leaves and bloom stem die again and has contractile origins that take it down further into the soil. The rose leaves and stem form in the light, to emerge the next season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the planting season, though a few species are autumn flowering.
