Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 flowers are generally white or yellowish (orange or pink in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true amount of kinds has varied, depending about how they are grouped, credited to similarity between kinds and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is anonymous, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The species are native 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 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, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others 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 hundred years and by the past due 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as slice flowers so that as ornamental plants in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of shapes and colours. Like other members of these 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the nationwide rose of Wales and the image of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights 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 may increase as high as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the light. The flower stem bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The blooms, which can be usually conspicuous and white or yellow, both or rarely 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 designed corona. The bouquets may hang down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant following the leaves and rose stem die back and has contractile root base that draw it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer time to past due winter, flowering in the planting season, though a few types are fall flowering.
