Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden types), with either even or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The number of types has mixed, depending about how they are labeled, a consequence of to similarity between hybridization and kinds. 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 source of the name Narcissus is unfamiliar, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slash flowers 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 classified into divisions, covering an array 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 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 books and fine art, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as icons of planting season. The daffodil is the national flower of Wales and the symbol of tumor charities in many countries. The looks of the wild flowers in spring and coil is associated with celebrations 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 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light bulb. The seed stem bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The bouquets, which can be conspicuous and white or yellowish usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berries includes a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant after the leaves and flower stem die back again and has contractile roots that draw it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from summertime to later winter, flowering in the spring, though a few varieties are fall flowering.
