Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 by a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or green in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with approximately 50 species. The true amount of species has varied, depending on how they are categorized, due to similarity between species and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the real name Narcissus is unfamiliar, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the ASIA to the tenth century prior. 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 grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as lower blooms so that as ornamental plant life in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members with their 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 treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in different cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the national blossom of Wales and the symbol of cancer charities in many countries. The looks of the outdoors flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light bulb. They regrow in the next time 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 level of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the light bulb. The flower stem bears a solitary flower, but once in a while a cluster of blooms (umbel). The bouquets, which are usually conspicuous and white or yellow, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and bloom stem die back again and has contractile origins that pull it down further into the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summer to late winter, flowering in the planting season, though a few varieties are autumn flowering.
