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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or red in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten parts with around 50 species. The true variety of kinds has assorted, depending about how they are labeled, due to similarity between hybridization and varieties. The genus arose some 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 unknown, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of this name who fell deeply in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The varieties are native to meadows and woods in southern European countries and North Africa with a centre of diversity in the European 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 insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as trim blossoms and as ornamental crops in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of their family, narcissi produce 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the national rose 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 again after flowering to the underground storage bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The place stem bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The blooms, that are conspicuous and white or yellow usually, both or hardly ever renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The flowers may suspend down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berries contains a dried up capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and flower stem die again and has contractile root base that draw it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the next season. Most varieties are dormant from summer months to overdue winter, flowering in the spring, though a few species are fall flowering.
