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 used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or red in garden varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true range of types has assorted, depending on how they are grouped, as a consequence to similarity between hybridization and types. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is unidentified, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The kinds are native to meadows and woods in southern European countries and North Africa with a center of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the late 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as slice blooms and as ornamental plants in private and general population gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of springtime. The daffodil is the countrywide bloom of Wales and the mark of cancers charities in many countries. The appearance of the outrageous flowers in springtime 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 following year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the bulb. The vegetable stem bears a solitary bloom, but occasionally a cluster of blooms (umbel). The blooms, which are conspicuous and white or yellowish usually, both or rarely green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The flowers may suspend 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 fruit consists of a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and bloom stem die back again and has contractile roots that move it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from warmer summer months to late winter, flowering in the spring, though a few varieties are fall months flowering.
