Narcissus /n?:r's?s?s/ is a genus of predominantly 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 a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or red in garden types), with either even or contrasting colored tepals and corona.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten sections with about 50 species. The true volume of kinds has assorted, depending about how they are labeled, thanks to similarity between hybridization and species. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is unidentified, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youth of that name who fell deeply in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern European countries 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 presented into the Far East to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the past due 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as slice blooms as ornamental vegetation in private and general population gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. 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 resulted in 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 different cultures, ranging from fatality to good fortune, and as symbols of springtime. The daffodil is the national blossom of Wales and the sign of tumor charities in many countries. The looks of the crazy flowers in spring and coil 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 bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the light bulb. The plant stem bears a solitary bloom, but occasionally a cluster of blooms (umbel). The blooms, which can be conspicuous and white or yellow usually, sometimes both or rarely renewable, consist of 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 molded corona. The plants may hang down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant following the leaves and rose stem die back and has contractile roots that move it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from summer months to overdue winter, flowering in the planting season, though a few varieties are fall flowering.
