Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 way of a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or red in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten sections with around 50 species. The amount of kinds has varied, depending on how they are classified, due to similarity between species 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 name Narcissus is unidentified, but it is linked to a Greek word for intoxicated (narcotic) and the myth of the children of that name who fell deeply in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were presented into 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, 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 earliest times, but became ever more popular in Europe after the 16th hundred years and by the later 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as trim flowers and as ornamental plant life 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 a variety of colours and shapes. Like other members with their family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. 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 artwork and books, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide bloom of Wales and the image 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 back after flowering to the underground storage light. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights 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 may develop as large as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the light. The flower stem bears a solitary rose, but sometimes a cluster of bouquets (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The plants may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb sits dormant following the leaves and blossom stem die again and has contractile root base that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summer months to past due winter, flowering in the planting season, though a few types are fall flowering.
