Description Narcissus botanical garden jerusalem.JPG

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands 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 a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden varieties), with either uniform or contrasting colored corona and tepals.

Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten portions with around 50 species. The true volume of species has assorted, depending on how they are classified, as a consequence to similarity between hybridization and types. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the true name Narcissus is unfamiliar, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own representation. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.

The kinds are native to meadows and woods in southern European countries and North Africa with a middle of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the ASIA 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 grown to be extinct, while some are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as lower bouquets so that as ornamental plant life in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of springtime. The daffodil is the nationwide flower of Wales and the sign of tumor charities in many countries. The appearance of the outdoors flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.

The crops are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves happen from the light. The place stem bears a solitary flower, but occasionally a cluster of plants (umbel). The plants, that are conspicuous and white or yellow usually, both or hardly ever green sometimes, 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 disc to conical formed corona. The bouquets may hang up down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dry out capsule that splits (dehisces) launching numerous black seeds.

The bulb sits dormant after the leaves and rose stem die again and has contractile root base that yank it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summer season to past due winter, flowering in the planting season, though a few kinds are fall months flowering.
