Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 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 historic civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with around 50 species. The true quantity of species has mixed, depending on how they are categorised, due to similarity between species and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is anonymous, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East to the tenth century prior. 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 become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as cut plants as ornamental plants in private and general population gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of colours and shapes. Like other members of their family, narcissi produce 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the national rose of Wales and the icon of tumors charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light bulb. They regrow in the following yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the light bulb. The place stem bears a solitary blossom, but once in a while a cluster of blooms (umbel). The flowers, that happen to be conspicuous and white or yellow usually, sometimes both or seldom green, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb sits dormant following the leaves and rose stem die back and has contractile roots that pull it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most types are dormant from summer months to past due winter, flowering in the springtime, though a few kinds are fall flowering.
