Hoa Thủy Tiên – Narcissus – Daffodil Tasuwka39;s Blog

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 blooms are usually white or yellow (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The amount of types has varied, depending how they are categorised, scheduled to similarity between species and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the real name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.

The types are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched 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, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the late 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as trim flowers as ornamental crops in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. 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 ingested inadvertently. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the nationwide flower of Wales and the sign of cancer tumor charities in many countries. The appearance of the crazy flowers in spring and coil is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the next calendar year from brown-skinned ovoid lights 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 extra tall as 80 cm.

The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the light bulb. The seed stem bears a solitary flower, but occasionally a cluster of blossoms (umbel). The blooms, that happen to be conspicuous and white or yellowish usually, sometimes both or almost never inexperienced, 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 shaped corona. The bouquets may suspend down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) launching numerous black seeds.

The bulb is dormant after the leaves and bloom stem die again and has contractile origins that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most species are dormant from warmer summer months to overdue winter, flowering in the spring and coil, though a few kinds are fall months flowering.
