Narcissus tazetta Bunchflower daffodil, Paperwhite daffodil

Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 green in garden types), with either uniform or contrasting coloured corona and tepals.

Narcissus were well known in historical civilisation, both medicinally and botanically, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The true quantity of varieties has varied, depending on how they are categorized, anticipated to similarity between species and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions 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 representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.

The types are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled into the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 after the 16th hundred years and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as slice blossoms so when ornamental plants in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members of their family, narcissi produce a 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the countrywide bloom of Wales and the icon of malignancy charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.

The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The plant stem bears a solitary bloom, but sometimes a cluster of plants (umbel). The plants, which are usually conspicuous and white or yellow, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) launching numerous black seeds.

The bulb sits dormant after the leaves and blossom stem die back again and has contractile roots that draw it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summertime to late winter, flowering in the springtime, though a few varieties are fall months flowering.
