Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names 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 with a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or green in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten parts with roughly 50 species. The amount of kinds has assorted, depending about how they are labeled, due 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 unknown, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of that 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 species are local to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 earliest times, but became ever more popular in Europe after the 16th hundred years and by the overdue 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as slice bouquets and since ornamental plants in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. 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 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 number of themes in various cultures, ranging from death to fortune, and as icons of planting season. The daffodil is the nationwide flower of Wales and the mark of tumors charities in many countries. The looks of the outdoors flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the bulb. The place stem bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The blooms, which can be conspicuous and white or yellowish usually, both or almost never inexperienced sometimes, 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 disc to conical molded corona. The bouquets may suspend down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry includes a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant following the leaves and bloom stem die back and has contractile root base that move it down further into the soil. The rose stem and leaves form in the light, to emerge the following season. Most species are dormant from summertime to overdue winter, flowering in the spring and coil, though a few kinds are fall months flowering.
