Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 with a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or red in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The true variety of kinds has varied, depending about how they are grouped, anticipated to similarity between types and hybridization. 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 precise origins of the name Narcissus is unidentified, but it is often 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 phrase 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The varieties are local 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 released into the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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 increasingly popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as lower blossoms and since ornamental crops in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members with 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as icons of planting season. The daffodil is the countrywide rose of Wales and the sign of malignancy charities in many countries. The appearance of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the light bulb. The vegetable stem usually bears a solitary flower, but sometimes a cluster of blossoms (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside 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 bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berry includes a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant following the leaves and blossom stem die back again and has contractile roots that pull it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer to late winter, flowering in the planting season, though a few species are fall flowering.
