Narcissus Bulb Fly the little buggers

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or green in garden varieties), with either even or contrasting colored corona and tepals.

Narcissus were popular in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with around 50 species. The true volume of varieties has mixed, depending about how they are labeled, as a consequence to similarity between hybridization and types. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is unknown, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The kinds are native to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. 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, nematodes and mites. Some Narcissus species have become 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 later 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as chop blooms and since ornamental vegetation in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. Like other members with their family, narcissi create a true 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, 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 national rose of Wales and the mark of cancers charities in many countries. The appearance of the outrageous flowers in springtime is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.

The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the bulb. The flower stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The blooms, that happen to be usually conspicuous and white or yellow, sometimes both or rarely renewable, contain 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 molded corona. The plants may suspend down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dry out capsule that splits (dehisces) liberating numerous black seeds.

The bulb lies dormant following the leaves and flower stem die back and has contractile root base that take it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summer season to overdue winter, flowering in the spring, though a few varieties are fall months flowering.
