Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 flowers are generally white or yellow (orange or pink in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten portions with roughly 50 species. The number of kinds has mixed, depending how they are classified, anticipated to similarity between varieties and hybridization. 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 name Narcissus is mysterious, but it is linked to a Greek word for intoxicated (narcotic) and the myth of the youth of that name who fell deeply in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The types are native to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released into the ASIA to the tenth hundred years 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, nematodes and mites. 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 past due 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as slash blossoms so that as ornamental vegetation in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members with their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 literature and art, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the nationwide blossom of Wales and the symbol of cancer charities in many countries. The looks of the untamed flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light. They regrow in the following time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The place stem usually bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The blooms, which are conspicuous and white or yellowish usually, sometimes both or almost never green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The bouquets 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) consisting of three chambers (trilocular). The fruits contains a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and rose stem die back and has contractile root base that take it down further into the soil. The bloom leaves and stem form in the light, to emerge the next season. Most kinds are dormant from warmer summer months to late winter, flowering in the spring, though a few kinds are autumn flowering.
