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 being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or pink in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with roughly 50 species. The true variety of types has varied, depending on how they are categorized, scheduled to similarity between types and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the name Narcissus is mysterious, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The types are indigenous to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as cut flowers and as ornamental vegetation in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members with 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the national blossom of Wales and the symbol of tumors charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light. They regrow in the next calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light bulb. The plant stem usually bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The blooms, which are conspicuous and white or yellowish usually, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe 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 flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb is placed dormant following the leaves and flower stem die back again and has contractile origins that pull it down further in to the soil. The blossom leaves and stem form in the light bulb, to emerge the following season. Most types are dormant from warmer summer months to past due winter, flowering in the springtime, though a few types are fall months flowering.
