Narcissus x incurvicervicus rule

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 bouquets are usually white or yellowish (orange or pink in garden varieties), with either uniform or contrasting coloured corona and tepals.

Narcissus were well known in traditional 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 approximately 50 species. The true range of varieties has mixed, depending on how they are labeled, as a consequence 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 exact origins of the true name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own reflection. The English word 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.

The species are native to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to 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 others 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 century and by the later 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as cut blossoms and as ornamental plants in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the countrywide flower of Wales and the symbol of cancers charities in many countries. The looks of the outdoors flowers in springtime is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.

The plants are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The seed stem usually bears a solitary blossom, but sometimes a cluster of flowers (umbel). The blossoms, which are conspicuous and white or yellowish 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 made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blossoms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries consists of a dried up capsule that splits (dehisces) launching numerous black seeds.

The bulb is dormant after the leaves and rose stem die again and has contractile origins that draw it down further in to the soil. The blossom stem and leaves form in the light, to emerge the next season. Most types are dormant from summer time to later winter, flowering in the springtime, though a few varieties are autumn flowering.
