Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 by way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or red in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten sections with approximately 50 species. The true volume of varieties has mixed, depending on how they are labeled, thanks to similarity between hybridization and species. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the real name Narcissus is unknown, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. 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, nematodes and mites. 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 ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as slice plants and as ornamental plants in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array 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 inadvertently. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the nationwide flower of Wales and the symbol of malignancy charities in many countries. The appearance of the wild flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage bulb. They regrow in the following season from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.
The vegetation are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The flower stem usually bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The flowers, that are usually conspicuous and white or yellowish, both or hardly ever inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The bouquets may suspend down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dried capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant following the leaves and rose stem die back and has contractile root base that yank it down further in to the soil. The rose leaves and stem form in the light, to emerge the next season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the spring, though a few types are fall months flowering.
