Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 with a cup- or trumpet-shaped corona. The blooms are generally white or yellowish (orange or pink in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten parts with approximately 50 species. The amount of varieties has varied, depending on how they are categorised, as a consequence to similarity between hybridization and species. 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 source of the real name Narcissus is mysterious, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a center of diversity in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. 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 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 century and by the past due 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as trim blossoms and as ornamental vegetation 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 colours and shapes. Like other members of the family, narcissi create a true 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 use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the countrywide bloom of Wales and the sign of tumor charities in many countries. The looks of the outrageous flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage bulb. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the bulb. The seed stem usually bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The blossoms, which are usually conspicuous and white or yellow, both or rarely inexperienced sometimes, 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 disk to conical formed corona. The flowers may hang up down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry contains a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant following the leaves and flower stem die again and has contractile roots that yank it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summer season to overdue winter, flowering in the planting season, though a few varieties are autumn flowering.
