Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 pink in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten sections with approximately 50 species. The true variety of types has varied, depending about how they are grouped, a consequence of to similarity between hybridization and kinds. 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 precise origin of the name Narcissus is unknown, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern European countries and North Africa with a centre 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 before the tenth century. Narcissi have a tendency 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 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 century were an important commercial crop centred primarily on holland. Today narcissi are popular as lower flowers and since ornamental crops in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi create 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 in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the image of tumor charities in many countries. The appearance of the outrageous flowers in springtime 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 bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The plant stem usually bears a solitary blossom, but occasionally a cluster of blooms (umbel). The blossoms, that happen to be usually conspicuous and white or yellowish, both or hardly ever renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The super fruit contains a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and flower stem die back again and has contractile roots that take it down further into the soil. The rose stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summer to overdue winter, flowering in the planting season, though a few species are autumn flowering.
