Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants 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 with a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or red in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with approximately 50 species. The true variety of species has varied, depending on how they are classified, as a consequence to similarity between hybridization and types. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the true name Narcissus is unidentified, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English word '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 Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as chop blooms so that ornamental plants in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create 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 treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the national blossom of Wales and the symbol of malignancy charities in many countries. The looks of the untamed 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 an underground storage light bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light. The flower stem usually bears a solitary rose, but once in a while a cluster of blossoms (umbel). The blossoms, that are conspicuous and white or yellow usually, sometimes both or hardly ever green, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blooms may hang down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dried up capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant after the leaves and bloom stem die again and has contractile origins that take it down further in to the soil. The flower leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summer months to overdue winter, flowering in the spring and coil, though a few varieties are autumn flowering.
