Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 red in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten portions with about 50 species. The amount of kinds has assorted, depending how they are classified, credited to similarity between varieties and hybridization. The genus arose a while 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 mysterious, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The varieties are local to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released into the ASIA to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders 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 overdue 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as slice plants and since ornamental crops in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. 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 unintentionally. 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 artwork and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the countrywide rose of Wales and the sign of cancer tumor charities in many countries. The looks of the crazy flowers in planting season 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 bulb. They regrow in the next calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light bulb. The place stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The blossoms, which can be conspicuous and white or yellow usually, sometimes both or seldom inexperienced, 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 disc to conical designed corona. The bouquets may suspend down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is substandard (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 after the leaves and rose stem die again and has contractile roots that yank it down further in to the soil. The rose leaves and stem form in the light, to emerge the next season. Most species are dormant from summertime to later winter, flowering in the planting season, though a few species are fall months flowering.
