Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants 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 historical civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with approximately 50 species. The number of kinds has varied, depending about how they are classified, due to similarity between species and hybridization. The genus arose some 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 unknown, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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 grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as slice bouquets so that as ornamental plants in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. Like other members of their family, narcissi create 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 use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as icons of spring. The daffodil is the countrywide blossom of Wales and the mark of tumor charities in many countries. The appearance of the wild flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the light. The flower stem bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The plants, that happen to be conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, 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 designed corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries contains a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant after the leaves and bloom stem die back again and has contractile roots that take it down further in to the soil. The blossom leaves and stem form in the light, to emerge the following season. Most types are dormant from summer to overdue winter, flowering in the planting season, though a few types are fall months flowering.
