Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 by the cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or green in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with about 50 species. The true volume of kinds has varied, depending how they are classified, due to similarity between varieties and hybridization. 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 unidentified, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The kinds are native to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created into the Far East to the tenth hundred years prior. Narcissi tend 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 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 generally on the Netherlands. Today narcissi are popular as cut plants so when ornamental vegetation in private and general population gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi produce a 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 utilization in traditional healing and has led to 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 different cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the national bloom of Wales and the icon of cancers charities in many countries. The appearance of the crazy flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid light 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 height of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the bulb. The plant stem bears a solitary blossom, but sometimes a cluster of plants (umbel). The blossoms, that are usually conspicuous and white or yellow, sometimes both or rarely inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may hang down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry contains a dry out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is placed dormant following the leaves and blossom stem die back again and has contractile origins that move it down further into the soil. The rose stem and leaves form in the light bulb, to emerge the next season. Most varieties are dormant from summer months to past due winter, flowering in the spring and coil, though a few types are fall months flowering.
