Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or pink in garden varieties), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with around 50 species. The true volume of varieties has assorted, depending how they are categorised, anticipated to similarity between species and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is mysterious, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the youth 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 compared commonly.
The species are local 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 presented into the ASIA to the tenth century prior. Narcissi tend 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 others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as cut flowers so when ornamental plants in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the nationwide bloom of Wales and the icon of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the light bulb. The herb stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The bouquets, which can be conspicuous and white or yellowish usually, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blossoms may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant following the leaves and blossom stem die again and has contractile origins that move it down further in to the soil. The flower leaves and stem form in the light, to emerge the next season. Most types are dormant from warmer summer months to past due winter, flowering in the springtime, though a few kinds are fall months flowering.
