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 used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or pink in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with around 50 species. The true volume of species has varied, depending on how they are grouped, scheduled to similarity between species and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the true name Narcissus is undiscovered, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the youngsters of that name who fell deeply in love with his own representation. The English phrase 'daffodil' appears to be 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 diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were presented in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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 earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as slice blooms and since ornamental plants in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of planting season. The daffodil is the nationwide bloom of Wales and the icon of tumor charities in many countries. The appearance of the outdoors flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the bulb. The herb stem usually bears a solitary flower, but once in a while a cluster of blossoms (umbel). The blooms, that happen to be usually conspicuous and white or yellow, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blooms may hang down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit involves a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and blossom stem die back again and has contractile roots that pull it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the following season. Most varieties are dormant from summer months to late winter, flowering in the spring, though a few varieties are autumn flowering.
