Hoa Thủy Tiên – Narcissus – Daffodil Tasuwka39;s Blog

Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 by the cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden varieties), with either standard or contrasting colored tepals and corona.

Narcissus were popular in historic civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The number of species has varied, depending about how they are classified, a consequence of to similarity between hybridization and species. 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 exact source of the name Narcissus is unknown, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The kinds are local to meadows and woods in southern Europe and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency 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, 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 initial times, but became ever more popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as chop plants so when ornamental plant life 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 an array of shapes and colours. Like other members of these family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 skill and books, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the nationwide rose of Wales and the sign of cancers charities in many countries. The looks 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 bulb. They regrow in the next season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.

The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the bulb. The vegetable stem bears a solitary flower, but once in a while a cluster of bouquets (umbel). The blooms, that happen to be conspicuous and white or yellowish usually, both or hardly ever inexperienced sometimes, contain 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 designed corona. The blooms may hang down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dried out capsule that splits (dehisces) releasing numerous black seeds.

The bulb lays dormant after the leaves and blossom stem die again and has contractile root base that yank it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most species are dormant from summertime to past due winter, flowering in the planting season, though a few kinds are autumn flowering.
