Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 the cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or red in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The number of varieties has assorted, depending about how they are categorized, thanks to similarity between hybridization and species. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the name Narcissus is unknown, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The types are native to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created in to the ASIA to the tenth hundred years prior. Narcissi tend 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 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 after the 16th hundred years and by the later 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as slice bouquets so that as ornamental plants 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 create 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in several cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the national flower of Wales and the image of tumor charities in many countries. The looks of the crazy flowers in spring is associated with celebrations 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 following time from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the light bulb. The vegetable stem bears a solitary flower, but occasionally a cluster of bouquets (umbel). The flowers, that are usually conspicuous and white or yellowish, sometimes both or almost never renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blooms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits contains a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant following the leaves and rose stem die back and has contractile roots that take it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most varieties are dormant from summer months to late winter, flowering in the planting season, though a few varieties are fall flowering.
