Narcissus Species and natural hybrids

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or red in garden kinds), with either standard or contrasting colored tepals and corona.

Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The true variety of species has assorted, depending on how they are categorised, credited 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 areas of southwest Europe. The precise origin of the name Narcissus is unknown, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.

The species are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched in to the Far East to the tenth hundred years prior. 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 some are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as lower bouquets and since ornamental vegetation in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of colours and shapes. Like other members of these 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 use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the national rose of Wales and the symbol of tumors charities in many countries. The appearance of the crazy flowers in spring and coil is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.

The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The place stem usually bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The bouquets, which can be conspicuous and white or yellow usually, both or hardly ever green sometimes, contain 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 disk to conical molded corona. The blooms may hang up down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dry out capsule that splits (dehisces) liberating numerous black seed products.

The bulb is dormant after the leaves and bloom stem die again and has contractile roots that take it down further in to the soil. The bloom stem and leaves form in the light, to emerge the next season. Most species are dormant from warmer summer months to later winter, flowering in the spring and coil, though a few types are autumn flowering.
