NARCISSUS BULBOCODIUM SEEDS

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 plants are generally white or yellowish (orange or green in garden kinds), with either even or contrasting coloured tepals and corona.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten areas with about 50 species. The number of varieties has varied, depending about how they are categorised, anticipated to similarity between varieties and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the true name Narcissus is unidentified, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.

The kinds are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched in to the ASIA to the tenth century prior. 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 grown to be extinct, while some 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 overdue 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as slice bouquets as ornamental crops in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi create 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in various cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the countrywide blossom of Wales and the mark of tumor 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 again after flowering to the underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.

The crops are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the bulb. The place stem usually bears a solitary blossom, but once in a while a cluster of blooms (umbel). The blooms, which are conspicuous and white or yellow usually, both or hardly ever green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry involves a dried up capsule that splits (dehisces) launching numerous black seed products.

The bulb lays dormant following the leaves and flower stem die back and has contractile roots that yank it down further in to the soil. The rose stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from warmer summer months to past due winter, flowering in the spring, though a few kinds are autumn flowering.
