Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or green in garden varieties), with either standard or contrasting colored corona and tepals.

Narcissus were well known in early civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The amount of types has varied, depending on how they are categorized, scheduled to similarity between species and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the true name Narcissus is mysterious, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.

The varieties are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to 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, 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 initial times, but became ever more popular in Europe following the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as cut blossoms so that ornamental plant life in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi create 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, 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 nationwide flower of Wales and the image of cancer charities in many countries. The looks of the crazy flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.

The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light bulb. The seed stem usually bears a solitary flower, but once in a while a cluster of bouquets (umbel). The flowers, which are usually conspicuous and white or yellowish, both or hardly ever inexperienced 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 disc to conical molded corona. The bouquets may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The super fruit consists of a dried up capsule that splits (dehisces) launching numerous black seeds.

The bulb is dormant following the leaves and flower stem die back again and has contractile root base that draw it down further into the soil. The blossom stem and leaves form in the light, to emerge the next season. Most species are dormant from summertime to overdue winter, flowering in the spring and coil, though a few varieties are fall flowering.
