Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The amount of kinds has assorted, depending on how they are categorized, anticipated to similarity between types and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is mysterious, but it is often associated with a Greek word 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' is apparently derived from "asphodel", with which it was commonly likened.
The kinds are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. 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, mites and nematodes. Some Narcissus species have grown to be extinct, while others 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 century and by the later 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as slice bouquets so that as ornamental plant life in private and general population gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of the family, narcissi create a 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 within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the nationwide bloom of Wales and the mark of tumors charities in many countries. The looks of the crazy flowers in spring is associated with festivals 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 following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the light bulb. The plant stem bears a solitary flower, but once in a while a cluster of blossoms (umbel). The plants, which are conspicuous and white or yellowish usually, both or seldom green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blooms may hang down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry includes a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and flower stem die again and has contractile origins that move it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most types are dormant from summer months to later winter, flowering in the spring, though a few varieties are fall months flowering.
