Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands 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 the cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or red in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with approximately 50 species. The amount of kinds has assorted, depending how they are categorized, scheduled to similarity between types and hybridization. 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 origin of the name Narcissus is anonymous, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The varieties are local 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 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 become 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 following the 16th hundred years and by the late 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as lower flowers so that as ornamental plant life in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised 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 ingested inadvertently. 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 art work and literature, narcissi are associated with a number of themes in different cultures, ranging from loss of life to fortune, and as symbols of spring and coil. The daffodil is the nationwide rose of Wales and the mark of tumors charities in many countries. The looks of the outdoors flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light bulb. The place stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The plants, which are conspicuous and white or yellow usually, 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 shaped corona. The blooms may suspend down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant following the leaves and rose stem die again and has contractile root base that draw it down further in to the soil. The rose stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the springtime, though a few varieties are fall months flowering.
