Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 with a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or pink in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten portions with around 50 species. The number of species has assorted, depending on how they are grouped, a consequence of to similarity between hybridization and kinds. 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 name Narcissus is unidentified, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the young ones of that name who fell deeply in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The kinds are native to meadows and woods in southern European countries and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. 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, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as slice plants so that ornamental vegetation in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range 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 within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the countrywide flower of Wales and the symbol of tumor charities in many countries. The appearance of the outrageous flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights 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 develop as large as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light bulb. The vegetable stem bears a solitary flower, but once in a while a cluster of blooms (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, both or almost never renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant after the leaves and flower stem die again and has contractile root base that take it down further into the soil. The flower leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summer season to past due winter, flowering in the spring, though a few varieties are fall flowering.
