Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names 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 plants are generally white or yellowish (orange or green in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten sections with about 50 species. The true amount of types has assorted, depending about how they are classified, a consequence of to similarity between hybridization and types. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the real name Narcissus is undiscovered, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend 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, 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 ever more popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as chop bouquets so that as ornamental crops in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. 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 inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring. The daffodil is the countrywide flower of Wales and the image of cancer charities in many countries. The appearance of the wild flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the next season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light. The seed stem usually bears a solitary rose, but sometimes a cluster of flowers (umbel). The blooms, which can be 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 external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The plants may hang up down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant following the leaves and flower stem die again and has contractile roots that draw it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer season to overdue winter, flowering in the planting season, though a few species are autumn flowering.
