Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with approximately 50 species. The true quantity of kinds has mixed, depending on how they are labeled, scheduled to similarity between types and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the name Narcissus is mysterious, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into 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, mites and nematodes. Some Narcissus species have grown to be 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 after the 16th century and by the past due 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as cut blooms so that as ornamental plants in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified 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 ingested accidentally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the nationwide bloom of Wales and the symbol of malignancy charities in many countries. The appearance of the crazy flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage bulb. They regrow in the next year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light. The plant stem bears a solitary blossom, but once in a while a cluster of flowers (umbel). The plants, which are usually conspicuous and white or yellowish, sometimes both or rarely inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The flowers may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries involves a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant after the leaves and blossom stem die again and has contractile roots that pull it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer months to past due winter, flowering in the springtime, though a few varieties are fall months flowering.
