Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or pink in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten parts with approximately 50 species. The true volume of types has assorted, depending about how they are labeled, a consequence of to similarity between hybridization and varieties. 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 origin of the real name Narcissus is anonymous, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of that name who fell deeply in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released in to the ASIA to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 initial times, but became ever more popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as chop bouquets so that as ornamental vegetation in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members of their 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the sign of cancer tumor charities in many countries. The appearance of the crazy flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as tall as 80 cm.
The crops 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 herb stem bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The plants, which are conspicuous and white or yellow usually, sometimes both or almost never inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit consists of a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant after the leaves and rose stem die again and has contractile roots that pull it down further into the soil. The flower leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summertime to past due winter, flowering in the planting season, though a few kinds are fall flowering.
