Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 with a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with roughly 50 species. The number of types has varied, depending on how they are grouped, as a consequence to similarity between hybridization and kinds. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is unfamiliar, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the children of this name who fell deeply in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern Europe and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled into the ASIA to the tenth hundred years prior. 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 grown to be 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 after the 16th century and by the late 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop flowers so that as ornamental crops in private and general population gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized 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 accidentally ingested. 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 artwork and books, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the icon of tumor charities in many countries. The appearance of the crazy flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the bulb. The flower stem usually bears a solitary rose, but sometimes a cluster of blossoms (umbel). The bouquets, which can be conspicuous and white or yellowish usually, both or hardly ever renewable 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 designed corona. The blossoms may hang down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb is dormant following the leaves and bloom stem die back again and has contractile root base that move it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from warmer summer months to past due winter, flowering in the spring and coil, though a few species are fall months flowering.
