Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or pink in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The true volume of species has varied, depending about how they are categorised, a consequence of to similarity between hybridization and kinds. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the true name Narcissus is mysterious, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before 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 become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop bouquets so when ornamental crops in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members of these family, narcissi produce 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 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 fortune, and as icons of springtime. The daffodil is the nationwide bloom of Wales and the mark of cancers charities in many countries. The appearance of the crazy flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage light bulb. They regrow in the following season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as large 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 bulb. The flower stem bears a solitary flower, but sometimes a cluster of blossoms (umbel). The plants, that are conspicuous and white or yellowish usually, both or seldom green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up 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 find six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruit involves a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant following the leaves and bloom stem die again and has contractile root base that pull it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer time to past due winter, flowering in the spring, though a few species are fall flowering.
