Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 by way of a cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or red in garden types), with either uniform or contrasting coloured corona and tepals.

Narcissus were popular in early civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The number of kinds has mixed, depending on how they are labeled, a consequence of to similarity between hybridization and varieties. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the name Narcissus is unfamiliar, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of that name who fell deeply in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.

The types are native to meadows and woods in southern Europe and North Africa with a centre of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. 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 become extinct, while some are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slash bouquets so that ornamental crops in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. 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 books and artwork, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the national flower of Wales and the sign of cancer tumor charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.

The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the light. The plant stem bears a solitary flower, but occasionally a cluster of plants (umbel). The plants, which are usually conspicuous and white or yellow, both or hardly ever renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruit contains a dry out capsule that splits (dehisces) launching numerous black seed products.

The bulb is situated dormant following the leaves and blossom stem die back and has contractile origins that pull it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summertime to overdue winter, flowering in the spring, though a few types are autumn flowering.
