Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 blossoms are generally white or yellow (orange or red in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten parts with around 50 species. The amount of types has assorted, depending about how they are categorized, anticipated to similarity between types 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 exact source of the true name Narcissus is unfamiliar, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East to the tenth century 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, 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 increasingly popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slice flowers and since ornamental plant life in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as icons of spring. The daffodil is the countrywide blossom of Wales and the mark of tumor charities in many countries. The appearance of the untamed 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 the underground storage light. They regrow in the next 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the bulb. The herb stem bears a solitary blossom, but sometimes a cluster of blooms (umbel). The blossoms, which are usually conspicuous and white or yellowish, sometimes both or seldom green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed 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 will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry contains a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant following the leaves and rose stem die back and has contractile origins that draw it down further into the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summer season to late winter, flowering in the planting season, though a few types are autumn flowering.
