Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 the cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with about 50 species. The true number of varieties has mixed, depending how they are categorised, 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 regions of southwest Europe. The exact source of the true name Narcissus is mysterious, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern Europe and North Africa with a middle of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before 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, nematodes and mites. Some Narcissus species have become extinct, while others 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 past due 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as lower flowers and as ornamental plant life in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of shapes and colours. Like other members with their 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 led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the nationwide rose of Wales and the mark of tumors charities in many countries. The appearance of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light bulb. The seed stem usually bears a solitary flower, but sometimes a cluster of blooms (umbel). The flowers, that are conspicuous and white or yellow usually, both or seldom green sometimes, 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 disc to conical formed corona. The flowers may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant after the leaves and bloom stem die back and has contractile root base that pull it down further in to the soil. The blossom stem and leaves form in the light, to emerge the following season. Most types are dormant from warmer summer months to late winter, flowering in the spring, though a few kinds are fall months flowering.
