Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 the cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or red in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten sections with around 50 species. The amount of varieties has varied, depending about how they are grouped, thanks to similarity between hybridization and species. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the real name Narcissus is undiscovered, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the ASIA 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, 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slash bouquets so when ornamental crops in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in different cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the national blossom of Wales and the mark of cancers charities in many countries. The looks of the untamed flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light bulb. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the light. The plant stem bears a solitary bloom, but occasionally a cluster of flowers (umbel). The blossoms, that happen to be usually conspicuous and white or yellow, sometimes both or rarely renewable, 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 disc to conical designed corona. The blossoms may hang up 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 fruit includes a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant following the leaves and flower stem die back again and has contractile roots that move it down further into the soil. The bloom leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summer months to overdue winter, flowering in the planting season, though a few types are fall flowering.
