Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or red in garden varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with roughly 50 species. The number of varieties has assorted, depending about how they are grouped, credited 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 areas of southwest Europe. The precise origins of the name Narcissus is unknown, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of that name who fell deeply in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The varieties are native to meadows and woods in southern European countries and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created 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, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as chop blossoms so that ornamental plants in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of their 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 resulted in 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 death to good fortune, and as symbols of springtime. The daffodil is the countrywide bloom of Wales and the image of tumor 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 a underground storage bulb. They regrow in the following time from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the bulb. The flower stem usually bears a solitary blossom, but sometimes a cluster of plants (umbel). The blossoms, that happen to be conspicuous and white or yellow usually, sometimes both or almost never inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The bouquets may hang down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is dormant after the leaves and rose stem die again and has contractile origins that take it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the following season. Most species are dormant from warmer summer months to overdue winter, flowering in the planting season, though a few species are autumn flowering.
