Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred primarily in the Netherlands. Today, narcissi are popular as cut flowers and as ornamental plants in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi produce a 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 resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of spring.
The daffodil is the national flower of Wales and the symbol of cancer charities in many countries. The appearance of wild flowers in spring is associated with festivals in many places.
Description
General
Narcissus is a genus of
The plants are
The bulb lies dormant after the leaves and flower stem die back and has contractile roots that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summer to late winter, flowering in the spring, though a few species are autumn flowering.[6]

The pale brown-skinned
Once the leaves die back in summer, the roots also wither. After some years, the roots shorten, pulling the bulbs deeper into the ground (
- Stems
The single leafless plant stem or scape, appearing from early to late spring depending on the species, bears from 1 to 20 blooms.[8] Stem shape depends on the species; some are highly compressed with a visible seam, while others are rounded. The stems are upright and located at the centre of the leaves. In a few species such as N. hedraeanthus the stem is oblique. The stem is hollow in the upper portion but towards the bulb is more solid and filled with a spongy material.[9]
- Leaves
Narcissus plants have one to several basal
Jonquils usually have dark green, round, rush-like leaves.[12]

- Flowers
The
The three major floral parts (in all species except N. cavanillesii in which the corona is virtually absent - Table I: Section Tapeinanthus) are:
- (i) the proximal floral tube(hypanthium),
- (ii) the surrounding free tepals, and
- (iii) the more distal corona(paraperigon, paraperigonium).
All three parts may be considered to be components of the
The floral tube is formed by fusion of the basal segments of the tepals (proximally connate). Its shape is from an inverted cone (obconic) to funnel-shaped (funneliform) or cylindrical, and is surmounted by the more distal corona. Floral tubes can range from long and narrow sections Apodanthi and Jonquilla to rudimentary (N. cavanillesii).[20]
Surrounding the floral tube and corona and
The corona, or paracorolla, is variously described as bell-shaped (funneliform, trumpet), bowl-shaped (cupular, crateriform, cup-shaped) or disc-shaped with margins that are often frilled, and is free from the stamens. Rarely is the corona a simple callose (hardened, thickened) ring. The corona is formed during floral development as a tubular outgrowth from stamens which fuse into a tubular structure, the anthers becoming reduced. At its base, the fragrances which attract pollinators are formed. All species produce nectar at the top of the ovary.[13] Coronal morphology varies from the tiny pigmented disk of N. serotinus (see Table I) or the rudimentary structure in N. cavanillesii to the elongated trumpets of section Pseudonarcissus (trumpet daffodils, Table I).[10][13][14][7]
While the perianth may point forwards, in some species such as N. cyclamineus it is folded back (reflexed, see illustration, left), while in some other species such as N. bulbocodium (Table I), it is reduced to a few barely visible pointed segments with a prominent corona.
The colour of the perianth is white, yellow or bicoloured, with the exception of the night flowering N. viridiflorus, which is green. In addition, the corona of N. poeticus has a red crenulate margin (see Table I).[11] Flower diameter varies from 12 mm (N. bulbocodium) to over 125 mm (N. nobilis=N. pseudonarcissus subsp. nobilis).[20]
Flower orientation varies from pendent or deflexed (hanging down) as in N. triandrus (see illustration, left), through declinate-ascendant as in N. alpestris = N. pseudonarcissus subsp. moschatus, horizontal (patent, spreading) such as N. gaditanus or N. poeticus, erect as in N. cavanillesii, N. serotinus and N. rupicola (Table I), or intermediate between these positions (erecto-patent).[9][11][13][14][17][21][20]
The flowers of Narcissus demonstrate exceptional floral diversity and sexual polymorphism,[17] primarily by corona size and floral tube length, associated with pollinator groups (see for instance Figs. 1 and 2 in Graham and Barrett[13]). Barrett and Harder (2005) describe three separate floral patterns:
- "Daffodil" form
- "Paperwhite" form
- "Triandrus" form.
The predominant patterns are the 'daffodil' and 'paperwhite' forms, while the "triandrus" form is less common. Each corresponds to a different group of pollinators (See Pollination).[17]
The "daffodil" form, which includes sections Pseudonarcissus and Bulbocodium, has a relatively short, broad or highly funnelform tube (funnel-like), which grades into an elongated corona, which is large and funnelform, forming a broad, cylindrical or trumpet-shaped perianth. Section Pseudonarcissus consists of relatively large flowers with a corolla length of around 50 mm, generally solitary but rarely in inflorescences of 2–4 flowers. They have wide greenish floral tubes with funnel-shaped bright yellow coronas. The six tepals sometimes differ in colour from the corona and may be cream coloured to pale yellow.[18]
The "paperwhite" form, including sections Jonquilla, Apodanthi and Narcissus, has a relatively long, narrow tube and a short, shallow, flaring corona. The flower is horizontal and fragrant.
The "triandrus" form is seen in only two species, N. albimarginatus (a Moroccan endemic) and N. triandrus. It combines features of both the "daffodil" and "paperwhite" forms, with a well-developed, long, narrow tube and an extended bell-shaped corona of almost equal length. The flowers are pendent.[17]
- Androecium
There are six stamens in one to two rows (whorls), with the filaments separate from the corona, attached at the throat or base of the tube (epipetalous), often of two separate lengths, straight or declinate-ascending (curving downwards, then upwards). The anthers are basifixed (attached at their base).[10][7]

History
Genus valde intricatum et numerosissimis dubiis oppressum
A genus that is very complex and burdened with numerous uncertainties— Schultes & Schultes fil., Syst. Veg. 1829[24]
Early
The genus Narcissus was well known to the
Modern
Various authors have adopted either narrow (e.g. Haworth,[41][42] Salisbury[43]) or wide (e.g.Herbert,[44] Spach[45] ) interpretations of the genus.[46] The narrow view treated many of the species as separate genera.[47] Over time, the wider view prevailed with a major monograph on the genus being published by Baker (1875).[48] One of the more controversial genera was Tapeinanthus,[49][47] but today it is included in Narcissus.[21]
The eventual position of Narcissus within the
Subdivision
The infrageneric phylogeny of Narcissus still remains relatively unsettled,[23] the taxonomy having proved complex and difficult to resolve,[14][18][21] due to the diversity of the wild species, the ease with which natural hybridization occurs, and extensive cultivation and breeding accompanied by escape and naturalisation.[23][52] Consequently, the number of accepted species has varied widely.[52]
De Candolle, in the first systematic taxonomy of Narcissus, arranged the species into named groups, and those names have largely endured for the various subdivisions since and bear his name as their authority.[37][38] The situation was confused by the inclusion of many unknown or garden varieties, and it was not until the work of Baker that the wild species were all grouped as sections under one genus, Narcissus.[48]
A common classification system has been that of Fernandes

Phylogenetics
The
A large molecular analysis by Zonneveld (2008) sought to reduce some of the paraphyly identified by Graham and Barrett. This led to a revision of the sectional structure.[52][60][62] While Graham and Barrett (2004)[13] had determined that subgenus Hermione was monophyletic, Santos-Gally et al. (2011)[60] did not. If two species excluded in the former study are removed from the analysis, the studies are in agreement, the species in question instead forming a clade with subgenus Narcissus. Some so-called nothosections have been proposed, to accommodate natural ('ancient') hybrids (nothospecies).[62]
Species

Estimates of the number of species in Narcissus have varied widely, from anywhere between 16 and almost 160,[52][56] even in the modern era. Linnaeus originally included six species in 1753, by 1784 there were fourteen[63] by 1819 sixteen,[64] and by 1831 Adrian Haworth had described 150 species.[41]
Much of the variation lies in the definition of species. Thus, a very wide view of each species, such as Webb's[14] results in few species, while a very narrow view such as that of Fernandes[53] results in a larger number.[21] Another factor is the status of hybrids, with a distinction between "ancient hybrids" and "recent hybrids". The term "ancient hybrid" refers to hybrids found growing over a large area, and therefore now considered as separate species, while "recent hybrid" refers to solitary plants found amongst their parents, with a more restricted range.[52]
Fernandes (1951) originally accepted 22 species,[55] Webb (1980) 27.[14] By 1968, Fernandes had 63 species,[53] Blanchard (1990) 65 species,[56] and Erhardt (1993) 66.[65] In 2006 the Royal Horticultural Society's (RHS) International Daffodil Register and Classified List [59][66][67] listed 87 species, while Zonneveld's genetic study (2008) resulted in only 36.[52] As of September 2014[update], the World Checklist of Selected Plant Families accepts 52 species, along with at least 60 hybrids,[68] while the RHS has 81 accepted names in its October 2014 list.[69]
Evolution
Within the
Names and etymology
Narcissus


The derivation of the Latin narcissus
It is frequently linked to the myth of Narcissus, who became so obsessed with his own reflection in water that he drowned and the narcissus plant sprang from where he died. There is no evidence for the flower being named after Narcissus. Narcissus poeticus, which grows in Greece, has a fragrance that has been described as intoxicating.[76] Pliny wrote that the plant was named for its fragrance (ναρκάω narkao, "I grow numb" ), rather than Narcissus.[23][27][77][78][79] Furthermore, there were accounts of narcissi growing long before the story of Narcissus appeared (see Greek culture).[74][80][Note 2] It has also been suggested that narcissi bending over streams represent the youth admiring his reflection.[81] Linnaeus used the Latin name "narcissus" for the plant but was preceded by others such as Matthias de l'Obel (1591)[82] and Clusius (1576).[83] The name Narcissus was not uncommon for men in Roman times.
The plural form of the common name "narcissus" has been the cause of some confusion. Dictionaries list "narcissi", "narcissuses" and "narcissus".[76][84][85] However, texts on usage such as Garner[86] and Fowler[87] state that "narcissi" is the preferred form. The common name narcissus should not be capitalised.
Daffodil
The name "daffodil" is derived from "affodell", a variant of

While the Amaryllidaceae are not native to North America, Narcissus grows well in USDA hardiness zones 3B through 10, which encompass most of the United States and Canada.[98]

However, unlike the above examples, most species have very restricted
The
Habitats
Their native habitats are very varied, with different elevations,
The Pseudonarcissus group in their natural habitat prefers humid situations such as stream margins, springs, wet pastures, clearings of forests or shrublands with humid soils, and moist hillsides. These habitats tend to be discontinuous in the Mediterranean mountains, producing discrete isolated populations.[18] In Germany, which has relatively little limestone, Narcissus pseudonarcissus grows in small groups on open mountain meadows or in mixed forests of fir, beech, oak, alder, ash and birch trees with well-drained soil.
Ecology
Life cycle
Narcissus are long-lived perennial geophytes with winter-growing and summer-dormant bulbs[18] that are mainly synanthous (leaves and flowers appearing at the same time).[6] While most species flower in late winter to spring, five species are autumn flowering (N. broussonetii, N. cavanillesii, N. elegans, N. serotinus, N. viridiflorus).[13] By contrast, these species are hysteranthous (leaves appear after flowering).[6]
Flower longevity varies by species and conditions, ranging from 5–20 days.
Plants may spread clonally through the production of daughter bulbs and division, producing clumps.[18] Narcissus species hybridise readily, although the fertility of the offspring will depend on the parental relationship.[23]
Pollination
The flowers are
- 'Daffodil' form. Pollinated by bees seeking approach herkogamycauses cross pollination.
- 'Paperwhite' form. These are adapted to long-tongued , while the short corona serves as a funnel guiding the tip of the proboscis into the mouth of the perianth tube. The stigma is placed either in the mouth of the tube, just above two whorls of three anthers, or hidden well below the anthers. The pollinators then carry pollen on their probosci or faces. The long-tongued bees cannot reach the nectar at the tube base and so collect just pollen.
- 'Triandrus' form. Pollinated by long-tongued solitary bees (Bombus), which forage for both pollen and nectar. The large corona allows the bees to crawl into the perianth but then the narrow tube prevents further progress, causing them to probe deeply for nectar. The pendant flowers prevent pollination by Lepidoptera. In N. albimarginatus there may be either a long stigma with short and mid-length anthers or a short stigma and long anthers (dimorphism). In N. triandrus there are three patterns of sexual organs (trimophism) but all have long upper anthers but vary in stigma position and the length of the lower anthers.[13][17]
Pests and diseases
Diseases of Narcissus are of concern because of the economic consequences of losses in commercial cultivation. Pests include viruses, bacteria, and fungi as well as arthropods and gastropods. For control of pests, see Commercial uses.
- Viruses
Less host specific viruses include
Of these viruses the most serious and prevalent are NDV, NYSV and NWSV.
- Fungi
More problematic for non-commercial plants is the fungus, Fusarium oxysporum f. sp. narcissi, which causes basal rot (rotting of the bulbs and yellowing of the leaves). This is the most serious disease of Narcissus. Since the fungus can remain in the soil for many years it is necessary to remove infected plants immediately, and to avoid planting further narcissi at that spot for a further five years. Not all species and cultivars are equally susceptible. Relatively resistant forms include N. triandrus, N. tazetta and N. jonquilla.[120][113][121][122]
Another fungus which attacks the bulbs, causing narcissus smoulder, is
Fungi affecting the roots include Nectria radicicola (Cylindrocarpon destructans), a cause of root rot[127] and Rosellinia necatrix causing white root rot,[128] while others affect root and bulb, such as Aspergillus niger (black mold), and species of Trichoderma, including T. viride and T. harzianum (=T. narcissi) responsible for green mold.[126]
Other fungi affect the remainder of the plant. Another Botrytis fungus,
- Animals
Other arthropods include Mites such as Steneotarsonemus laticeps (Bulb scale mite),[139] Rhizoglyphus and Histiostoma infest mainly stored bulbs and multiply particularly at high ambient temperature, but do not attack planted bulbs.[117]
Planted bulbs are susceptible to nematodes, the most serious of which is Ditylenchus dipsaci (Narcissus eelworm), the main cause of basal plate disease[140] in which the leaves turn yellow and become misshapen. Infested bulbs have to be destroyed; where infestation is heavy avoiding planting further narcissi for another five years.[117][141][142][143] Other nematodes include Aphelenchoides subtenuis, which penetrates the roots causing basal plate disease[140][144] and Pratylenchus penetrans (lesion nematode) the main cause of root rot in narcissi.
Conservation
Many of the smallest species have become extinct, requiring vigilance in the conservation of the wild species.
In response, a number of species have been granted protected species status and protected areas (meadows) have been established such as the

Of all the flowering plants, the bulbous have been the most popular for cultivation.
Cultivation is also documented in Britain at this time,[153][154][155] although contemporary accounts show it was well known as a favourite garden and wild flower long before that and was used in making garlands.[156] This was a period when the development of exotic formal gardens and parks was becoming popular, particularly in what is known as the "Oriental period" (1560–1620). In his Hortus Medicus (1588), the first catalogue of a German garden's plants,[157] Joachim Camerarius the Younger states that nine different types of daffodils were represented in his garden in Nuremberg.[158] After his death in 1598, his plants were moved by Basilius Besler to the gardens they had designed at Willibaldsburg, the bishop's palace at Eichstätt, Upper Bavaria. That garden is described in Besler's Hortus Eystettensis (1613) by which time there were 43 different types present.[159] Another German source at this time was Peter Lauremberg who gives an account of the species known to him and their cultivation in his Apparatus plantarius: de plantis bulbosis et de plantis tuberosis (1632).[160]
While
In the early seventeenth century, Parkinson helped to ensure the popularity of the daffodil as a cultivated plant[161] by describing a hundred different varieties in his Paradisus Terrestris (1629),[164] and introducing the great double yellow Spanish daffodil (Pseudonarcissus aureus Hispanicus flore pleno or Parkinson's Daffodil, see illustration) to England.[165]
I thinke none ever had this kind before myselfe nor did I myself ever see it before the year 1618 for it is of mine own raising and flowering first in my own garden
— John Parkinson, Paradisus Terrestris 1632[165]

In gardens
While some wild narcissi are specific in terms of their ecological requirements, most garden varieties are relatively tolerant of soil conditions,[175] however very wet soils and clay soils may benefit from the addition of sand to improve drainage.[176] The optimum soil is a neutral to slightly acid pH of 6.5–7.0.[175]
Bulbs offered for sale are referred to as either 'round' or 'double nose'. Round bulbs are circular in cross section and produce a single flower stem, while double nose bulbs have more than one bulb stem attached at the base and produce two or more flower stems, but bulbs with more than two stems are unusual.[177] Planted narcissi bulbs produce daughter bulbs in the axil of the bulb scales, leading to the dying off the exterior scales.[175] To prevent planted bulbs forming more and more small bulbs, they can be dug up every 5–7 years, and the daughters separated and replanted separately, provided that a piece of the basal plate, where the rootlets are formed, is preserved. For daffodils to flower at the end of the winter or early spring, bulbs are planted in autumn (September–November). This plant does well in ordinary soil but flourishes best in rich soil. Daffodils like the sun but also accept partial shade exposure.[citation needed]
Narcissi are well suited for planting under small thickets of trees, where they can be grouped as 6–12 bulbs.
Propagation
The commonest form of commercial propagation is by twin-scaling, in which the bulbs are cut into many small pieces but with the two scales still connected by a small fragment of the basal plate. The fragments are disinfected and placed in nutrient media. Some 25–35 new plants can be produced from a single bulb after four years. Micropropagation methods are not used for commercial production but are used for establishing commercial stock.[180][142]
Breeding
For commercial use, varieties with a minimum stem length of 30 centimetres (12 in) are sought, making them ideal for cut flowers. Florists require blooms that only open when they reach the retail outlet. For garden plants the objectives are to continually expand the colour palette and to produce hardy forms, and there is a particular demand for miniature varieties. The cultivars so produced tend to be larger and more robust than the wild types.[6] The main species used in breeding are N. bulbocodium, N. cyclamineus, N. jonquilla, N. poeticus, N. pseudonarcissus, N. serotinus and N. tazetta.[181]
Narcissus pseudonarcissus gave rise to trumpet
Classification
For horticultural purposes, all Narcissus cultivars are split into 13 divisions as first described by Kington (1998), The classification is a useful tool for planning planting. Most commercially available narcissi come from Divisions 1 (Trumpet), 2 (Large cupped) and 8 (Tazetta).
Growers register new daffodil cultivars by name and colour with the Royal Horticultural Society, which is the international registration authority for the genus.[66] Their International Daffodil Register is regularly updated with supplements available online[66] and is searchable.[21][67] The most recent supplement (2014) is the sixth (the fifth was published in 2012).[184] More than 27,000 names were registered as of 2008,[184] and the number has continued to grow. Registered daffodils are given a division number and colour code[185] such as 5 W-W ("Thalia").[186] In horticultural usage it is common to also find an unofficial Division 14: Miniatures, which although drawn from the other 13 divisions, have their miniature size in common.[187] Over 140 varieties have gained the Royal Horticultural Society's Award of Garden Merit (See List of Award of Garden Merit narcissus).
Colour code

Daffodil breeding has introduced a wide range of colours, in both the outer perianth tepal segment and the inner corona. In the registry, daffodils are coded by the colours of each of these two parts. Thus "Geranium", Tazetta (Division 8) as illustrated here with a white outer perianth and orange corona is classified as 8 W-O.
Toxicity
Pharmacology
All Narcissus species contain the
The toxic effects of ingesting Narcissus products for both humans and animals (such as cattle, goats, pigs, and cats) have long been recognised and they have been used in suicide attempts. Ingestion of N. pseudonarcissus or N. jonquilla is followed by
The toxicity of Narcissus varies with species, N. poeticus being more toxic than N. pseudonarcissus, for instance. The distribution of toxins within the plant also varies, for instance, there is a five times higher concentration of alkaloid in the stem of N. papyraceus than in the bulb, making it dangerous to herbivores more likely to consume the stem than the bulb, and is part of the plant's defence mechanisms. The distribution of alkaloids within tissues may also reflect defence against parasites.[23] The bulbs can also be toxic to other nearby plants, including roses, rice, and cabbages, inhibiting growth.[23] For instance placing cut flowers in a vase alongside other flowers shortens the life of the latter.[190]
Poisoning
Many cases of poisoning or death have occurred when narcissi bulbs have been mistaken for
On 1 May 2009, a number of schoolchildren fell ill at Gorseland Primary School in Martlesham Heath, Suffolk, England, after a daffodil bulb was added to soup during a cookery class.[188]
Topical effects
One of the most common dermatitis problems for flower pickers, packers, florists, and gardeners, "daffodil itch", involves dryness, fissures, scaling, and erythema in the hands, often accompanied by subungual hyperkeratosis (thickening of the skin beneath the nails). It is blamed on exposure to calcium oxalate, chelidonic acid or alkaloids such as lycorine in the sap, either due to a direct irritant effect or an allergic reaction.[191][192] It has long been recognised that some cultivars provoke dermatitis more readily than others. N. pseudonarcissus and the cultivars "Actaea", "Camparelle", "Gloriosa", "Grande Monarque", "Ornatus", "Princeps" and "Scilly White" are known to do so.[23][193]
If bulb extracts come into contact with wounds, both central nervous system and cardiac symptoms may result. The scent can also cause toxic reactions such as headaches and vomiting from N. bulbocodium.[23]

Biological properties
Extracts of Narcissus have demonstrated a number of potentially useful biological properties including
It is likely that the traditional use of narcissi for the treatment of cancer was due to the presence of isocarbostyril constituents such as narciclasine, pancratistatin and their congeners. N. poeticus contains about 0.12g of narciclasine per kg of fresh bulbs.[190]
Acetylcholine esterase inhibition has attracted the most interest as a possible therapeutic intervention, with activity varying by a thousandfold between species, and the greatest activity seen in those that contain galantamine or epinorgalanthamine.[61]
The rodent repellant properties of Narcissus alkaloids have been utilised in horticulture to protect more vulnerable bulbs.[201]

"Carlton" and "Ice Follies" (Division 2: Large cup) have a long history of cultivation, together with "Dutch Master" and "Golden Harvest" (1: yellow). "Carlton" and "Golden Harvest" were introduced in 1927, and "Ice Follies" in 1953. "Carlton", with over 9 billion bulbs (350 000 tons), is among the more numerous individual plants produced in the world.[204] The other major areas of production are the United States,[150] Israel which exported 25 million N. tazetta cultivar bulbs in 2003,[203] and the United Kingdom.
In the United Kingdom a total of 4100 ha were planted with bulbs, of which 3800 ha were Narcissi, the UK's most important bulb crop, much of which is for export,[205] making this the largest global production centre, about half of the total production area. While some of the production is for forcing, most is for dry bulb production. Bulb production and forcing occurs in the East, while production in the south west is mainly for outdoor flower production.[206] The farm gate value was estimated at £10m in 2007.[207]

Production of both bulbs and cut flowers takes place in open fields in beds or ridges, often in the same field, allowing adaptation to changing market conditions. Narcissi grow best in mild maritime climates. Compared to the United Kingdom, the harsher winters in the Netherlands require covering the fields with straw for protection. Areas with higher rainfall and temperatures are more susceptible to diseases that attack crops. Production is based on a 1 (UK) or 2 (Netherlands) year cycle. Optimal soil pH is 6.0–7.5. Prior to planting disinfection by hot water takes place, such as immersion at 44.4 °C for three hours.[142]
Bulbs are harvested for market in the summer, sorted, stored for 2–3 weeks, and then further disinfected by a hot (43.5 °C) bath. This eliminates infestations by narcissus fly and nematodes. The bulbs are then dried at a high temperature, and then stored at 15.5 °C.[6] The initiation of new flower development in the bulb takes place in late spring before the bulbs are lifted, and is completed by mid summer while the bulbs are in storage. The optimal temperature for initiation is 20 °C followed by cooling to 13 °C.[7]
Traditionally, sales took place in the daffodil fields prior to harvesting the bulbs, but today sales are handled by Marketing Boards although still before harvesting. In the Netherlands there are special exhibition gardens for major buyers to view flowers and order bulbs, some larger ones may have more than a thousand narcissus varieties on display. While individuals can visit these gardens they cannot buy bulbs at
Forcing
There is also a market for forced blooms, both as cut flowers and potted flowers through the winter from Christmas to Easter, the long season requiring special preparation by growers.
Cut flowers
For cut flowers, bulbs larger than 12 cm in size are preferred. To bloom in December, bulbs are harvested in June to July, dried, stored for four days at 34 °C, two weeks at 30 and two weeks at 17–20 °C and then placed in cold storage for precooling at 9 degrees for about 15–16 weeks. The bulbs are then planted in light compost in crates in a greenhouse for forcing at 13 °C–15 °C and the blooms appear in 19–30 days.[6][142]
Potted flowers
For potted flowers a lower temperature is used for precooling (5 °C for 15 weeks), followed by 16 °C–18 °C in a greenhouse. For later blooming (mid- and late-forcing), bulbs are harvested in July to August and the higher temperatures are omitted, being stored a 17–20 °C after harvesting and placed in cold storage at 9 °C in September for 17–18 (cut flowers) or 14–16 (potted flowers) weeks. The bulbs can then be planted in cold frames, and then forced in a greenhouse according to requirements.[142] N. tazetta and its cultivars are an exception to this rule, requiring no cold period. Often harvested in October, bulbs are lifted in May and dried and heated to 30 °C for three weeks, then stored at 25 °C for 12 weeks and planted. Flowering can be delayed by storing at 5 °C–10 °C.[113]
Culture
Symbols

The daffodil is the national flower of Wales, associated with Saint David's Day (March 1). The narcissus is also a national flower symbolising the new year or Nowruz in the Kurdish culture.
In the West the narcissus is perceived as a symbol of vanity, in the East as a symbol of wealth and good fortune (Persian literature, the narcissus is a symbol of beautiful eyes.
), while inIn western countries the daffodil is also associated with spring festivals such as Lent and its successor Easter. In Germany the wild narcissus, N. pseudonarcissus, is known as the Osterglocke or "Easter bell." In the United Kingdom the daffodil is sometimes referred to as the Lenten lily.[93][94][Note 4]
Although prized as an ornamental flower, some people consider narcissi unlucky, because they hang their heads implying misfortune.[23] White narcissi, such as N triandrus "Thalia", are especially associated with death, and have been called grave flowers.[208][209] In Ancient Greece narcissi were planted near tombs, and Robert Herrick describes them as portents of death, an association which also appears in the myth of Persephone and the underworld ( ).
Art
Antiquity

The decorative use of narcissi dates as far back as
Greek culture
The narcissus appears in two
The Greek poet

Other Greek authors making reference to the narcissus include Sophocles and Plutarch. Sophocles, in Oedipus at Colonus utilises narcissus in a symbolic manner, implying fertility,[218] allying it with the cults of Demeter and her daughter Kore (Persephone),[219] and by extension, a symbol of death.[220] Jebb comments that it is the flower of imminent death with its fragrance being narcotic, emphasised by its pale white colour. Just as Persephone reaching for the flower heralded her doom, the youth Narcissus gazing at his own reflection portended his own death.[219] Plutarch refers to this in his Symposiacs as numbing the nerves causing a heaviness in the limbs.[221] He refers to Sophocles' "crown of the great Goddesses", which is the source of the English phrase "Chaplet of the infernal Gods" incorrectly attributed to Socrates.[74]
A passage by
Roman culture
Virgil, the first known Roman writer to refer to the narcissus, does so in several places, for instance twice in the Georgics.[233] Virgil refers to the cup shaped corona of the narcissus flower, allegedly containing the tears of the self-loving youth Narcissus.[234] Milton makes a similar analogy "And Daffodillies fill their Cups with Tears".[235] Virgil also mentions narcissi three times in the Eclogues.[236][237]
The poet
Western culture
I wandered lonely as a Cloud
That floats on high o'er Vales and Hills,
When all at once I saw a crowd
A host of dancing Daffodils;
Along the Lake, beneath the trees,
Ten thousand dancing in the breeze.
The waves beside them danced, but they
Outdid the sparkling waves in glee: –
A poet could not but be gay
In such a laughing company:
I gaz'd – and gaz'd – but little thought
What wealth the shew to me had brought:
For oft when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude,
And then my heart with pleasure fills,
And dances with the Daffodils.
Although there is no clear evidence that the flower's name derives directly from the Greek myth, this link between the flower and the myth became firmly part of western culture. The narcissus or daffodil is the most loved of all English plants,
Shakespeare,
More recently A. E. Housman, using one of the daffodil's more symbolic names (see Symbols), wrote The Lent Lily in A Shropshire Lad, describing the traditional Easter death of the daffodil.[261]
In Black Narcissus, Rumer Godden describes the disorientation of English nuns in the Indian Himalayas, and gives the plant name an unexpected twist, alluding both to narcissism and the effect of the perfume Narcisse Noir (Caron) on others. The novel was later adapted into the 1947 British film of the same name. The narcissus also appears in German literature such as that of Paul Gerhardt.[262]
In the visual arts, narcissi are depicted in three different contexts, mythological (Narcissus, Persephone), floral art, or landscapes. The Narcissus story has been popular with painters and the youth is frequently depicted with flowers to indicate this association.

Popular culture
The word "daffodil" has been used widely in popular culture, from Dutch cars (DAF Daffodil) to films (Daffodils) to slurs against homosexuals and cross-dressers (as in the film J. Edgar, when Hoover's mother explains why real-life cross-dresser Barton Pinkus[288] was called "Daffy" (short for "Daffodil" and the equivalent of a pansy[289]), and admonishes, "I'd rather have a dead son than a daffodil for a son".[290][291][292][293][294]
Festivals
In some areas where narcissi are prevalent, their blooming in spring is celebrated in festivals. For instance, the slopes around Montreux, Switzerland and its associated riviera come alive with blooms each May (May Snow) at the annual Narcissi Festival.[295] Festivals are also held in many other countries.

Notes
- ^ The word "daffodil" is also applied to related genera such as Sternbergia, Ismene, and Fritillaria meleagris. It has been suggested that the word "Daffodil" be restricted to the wild species of the British Isles, N. pseudonarcissus. (Halevy 1985, Rees A.R. Narcissus, pp. 268–271)
- ^ Prior here refers to the poet Pamphilus, but it is likely he meant Pamphos.
- ^ This Carlavirus should not be confused with the similarly named Narcissus latent virus which is a Macluravirus.
- ^ Rarely "Lentern", especially ecclesiastical usage as here, or dialect, particularly Scottish (Masefield 2014, p. 104)(Jamieson 1879, Care Sonday vol I p. 284)(Wright 1905, vol 3 H–L, Lentren p. 575)
- ^ The Asphodel of the Greek underworld has been variously associated with the white Asphodelus ramosus (Macmillan (1887)) or the yellow Asphodeline lutea (Graves (1949)), previously classified as Asphodelus luteus.
