Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 bouquets are usually white or yellow (orange or green in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with approximately 50 species. The true range of species has assorted, depending about how they are categorized, a consequence of to similarity between hybridization and kinds. The genus arose a while 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 undiscovered, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 initial times, but became ever more popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as lower plants so that as ornamental crops in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members of the family, narcissi produce a 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the nationwide blossom of Wales and the mark of tumors charities in many countries. The appearance of the outrageous flowers in planting season 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. They regrow in the following calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels 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 might increase as high as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light. The herb stem bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The bouquets, which can be usually conspicuous and white or yellow, both or rarely green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blossoms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant following the leaves and blossom stem die again and has contractile origins that pull it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summertime to overdue winter, flowering in the springtime, though a few species are fall months flowering.
