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 being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or red in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The number of varieties has mixed, depending how they are grouped, as a consequence 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 exact origin of the name Narcissus is unidentified, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released in to 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, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as trim plants and as ornamental plants in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of these family, narcissi create a 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 resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of springtime. The daffodil is the nationwide rose of Wales and the image of tumor charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations 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 next 12 months from brown-skinned ovoid light 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 elevation of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the light bulb. The flower stem bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The flowers, that happen to be usually conspicuous and white or yellow, sometimes both or seldom inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry involves a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and rose stem die again and has contractile roots that draw it down further into the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer to overdue winter, flowering in the springtime, though a few species are autumn flowering.
