Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 the cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or green in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with about 50 species. The true amount of kinds has varied, depending on how they are classified, due to similarity between species and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is unknown, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into 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, nematodes and mites. Some Narcissus species have grown to be extinct, while some 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 hundred years and by the overdue 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as slash bouquets and as ornamental vegetation in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi produce a 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 within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the sign of cancer tumor charities in many countries. The looks of the outdoors flowers in planting season is associated with festivals 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 next calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the bulb. The herb stem usually bears a solitary bloom, but occasionally a cluster of bouquets (umbel). The bouquets, which can be usually conspicuous and white or yellowish, both or rarely inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blossoms may hang down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The super fruit consists of a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lays dormant after the leaves and blossom stem die back again and has contractile roots that pull it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the following season. Most species are dormant from warmer summer months to past due winter, flowering in the planting season, though a few varieties are autumn flowering.
