Tulipa Pavlovii

Tulips (''Tulipa'') are a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs). The flowers are usually large, showy and brightly coloured, generally red, pink, yellow, or white (usually in warm colours). They often have a different coloured blotch at the base of the tepals (petals and sepals, collectively), internally. Because of a degree of variability within the populations, and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to ''Amana'', '' Erythronium'' and '' Gagea'' in the tribe Lilieae.

There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble by those who discovered it. Tulips originally were found in a band stretching from Southern Europe to Central Asia, but since the seventeenth century have become widely naturalised and cultivated (''see map''). In their natural state they are adapted to steppes and mountainous areas with temperate climates. Flowering in the spring, they become dormant in the summer once the flowers and leaves die back, emerging above ground as a shoot from the underground bulb in early spring.

Growing wild over much of the Near East and Central Asia, tulips were cultivated in Constantinople as early as 1055. By the 15th century, tulips were among the most prized flowers; becoming the symbol of the Ottomans. While tulips had probably been cultivated in Persia from the tenth century, they did not come to the attention of the West until the sixteenth century, when Western diplomats to the Ottoman court observed and reported on them. They were rapidly introduced into Europe and became a frenzied commodity during tulip mania. Tulips were frequently depicted in Dutch Golden Age paintings, and have become associated with the Netherlands, the major producer for world markets, ever since. In the seventeenth century Netherlands, during the time of the tulip mania, an infection of tulip bulbs by the tulip breaking virus created variegated patterns in the tulip flowers that were much admired and valued. While truly broken tulips are not cultivated anymore, the closest available specimens today are part of the group known as the Rembrandts – so named because Rembrandt painted some of the most admired breaks of his time.

Breeding programmes have produced thousands of hybrid and cultivars in addition to the original species (known in horticulture as botanical tulips). They are popular throughout the world, both as ornamental garden plants and as cut flowers.

Description

''Tulipa'' (tulips) is a genus of spring-blooming perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. Depending on the species, tulip plants can be between high.

Flowers: The tulip's flowers are usually large and are actinomorphic (radially symmetric) and hermaphrodite (contain both male ( androecium) and female ( gynoecium) characteristics), generally erect, or more rarely pendulous, and are arranged more usually as a single terminal flower, or when pluriflor as two to three (e.g. '' Tulipa turkestanica''), but up to four, flowers on the end of a floriferous stem ( scape), which is single arising from amongst the basal leaf rosette. In structure, the flower is generally cup or star shaped. As with other members of Liliaceae the perianth is undifferentiated ( perigonium) and biseriate (two whorled), formed from six free (i.e. apotepalous) caducous tepals arranged into two separate whorls of three parts ( trimerous) each. The two whorls represent three petals and three sepals, but are termed tepals because they are nearly identical. The tepals are usually petaloid (petal like), being brightly coloured, but each whorl may be different, or have different coloured blotches at their bases, forming darker colouration on the interior surface. The inner petals have a small, delicate cleft at the top, while the sturdier outer ones form uninterrupted ovals.

Androecium: The flowers have six distinct, basifixed introrse stamens arranged in two whorls of three, which vary in length and may be glabrous or hairy. The filaments are shorter than the tepals and dilated towards their base.

Gynoecium: The style is short or absent and each stigma has three distinct lobes, and the ovaries are superior, with three chambers.

Fruit: The tulip's fruit is a globose or ellipsoid capsule with a leathery covering and an ellipsoid to globe shape. Each capsule contains numerous flat, disc-shaped seeds in two rows per chamber. These light to dark brown seeds have very thin seed coats and endosperm that does not normally fill the entire seed.

Leaves: Tulip stems have few leaves. Larger species tend to have multiple leaves. Plants typically have two to six leaves, some species up to 12. The tulip's leaf is cauline (born on a stem), strap-shaped, with a waxy coating, and the leaves are alternate (alternately arranged on the stem), diminishing in size the further up the stem. These fleshy blades are often bluish-green in colour.The bulbs are truncated basally and elongated towards the apex. They are covered by a protective tunic (tunicate) which can be glabrous or hairy inside.

Colours

The "Semper Augustus" was the most expensive tulip during the 17th-century tulip mania. “The colour is white, with Carmine on a blue base, and with an unbroken flame right to the top” – wrote Nicolas van Wassenaer in 1624 after seeing the tulip in the garden of one Dr Adriaen Pauw, a director of the new East India Company. With limited specimens in existence at the time and most owned by Pauw, his refusal to sell any flowers, despite wildly escalating offers, is believed by some to have sparked the mania.

Tulip flowers come in a wide variety of colours, except pure blue (several tulips with "blue" in the name have a faint violet hue), and have absent nectaries. Tulip flowers are generally bereft of scent and are the coolest of floral characters. The Dutch regarded this lack of scent as a virtue, as it demonstrates the flower's chasteness.

While tulips can be bred to display a wide variety of colours, black tulips have historically been difficult to achieve. The Queen of the Night tulip is as close to black as a flower gets, though it is, in fact, a dark and glossy maroonish purple - nonetheless, an effect prized by the Dutch. The first truly black tulip was bred in 1986 by a Dutch flower grower in Bovenkarspel, Netherlands. The specimen was created by cross-breeding two deep purple tulips, the Queen of the Night and Wienerwald tulips.

Phytochemistry

Tulipanin is an anthocyanin found in tulips. It is the 3-rutinoside of delphinidin. The chemical compounds named tuliposides and tulipalins can also be found in tulips and are responsible for allergies. Tulipalin A, or α-methylene-γ-butyrolactone, is a common allergen, generated by hydrolysis of the glucoside tuliposide A. It induces a dermatitis that is mostly occupational and affects tulip bulb sorters and florists who cut the stems and leaves. Tulipanin A and B are toxic to horses, cats and dogs. The colour of a tulip is formed from two pigments working in concert; a base colour that is always yellow or white, and a second laid-on anthocyanin colour. The mix of these two hues determines the visible unitary colour. The breaking of flowers occurs when a virus suppresses anthocyanin and the base colour is exposed as a streak.

Fragrance

The great majority of tulips, both species and cultivars, have no discernable scent, but a few of both are scented to a degree, and Anna Pavord describes ''T. Hungarica'' as "strongly scented", and among cultivars, some such as "Monte Carlo" and "Brown Sugar" are "scented", and "Creme Upstar" "fragrant".

Taxonomy

''Tulipa'' is a genus of the lily family, Liliaceae, once one of the largest families of monocots, but which molecular phylogenetics has reduced to a monophyletic grouping with only 15 genera. Within Liliaceae, ''Tulipa'' is placed within Lilioideae, one of three subfamilies, with two tribes. Tribe Lilieae includes seven other genera in addition to ''Tulipa''.

Subdivision

The genus, which includes about 75 species, is divided into four subgenera.
* ''Clusianae'' (4 species)
* ''Orithyia'' (4 species)
* ''Tulipa'' (52 species)
* ''Eriostemones'' (16 species)

Etymology

The word ''tulip'', first mentioned in western Europe in or around 1554 and seemingly derived from the "Turkish Letters" of diplomat Ogier Ghiselin de Busbecq, first appeared in English as ''tulipa'' or ''tulipant'', entering the language by way of french: tulipe and its obsolete form ''tulipan'' or by way of Modern Latin ''tulipa'', from Ottoman Turkish ''tülbend'' (" muslin" or "gauze"), and may be ultimately derived from the fa, دلبند ''delband'' (" Turban"), this name being applied because of a perceived resemblance of the shape of a tulip flower to that of a turban. This may have been due to a translation error in early times when it was fashionable in the Ottoman Empire to wear tulips on turbans. The translator possibly confused the flower for the turban.

Ogier Ghiselin de Busbecq stated that the "Turks" used the word "tulipan" to describe the flower. Extensive speculation has tried to understand why he would state this, given that the Turkish word for tulip is "lale". It is from this speculation that "tulipan" being a translation error referring to turbans is derived. This Etymology has been challenged and makes no assumptions about possible errors. At no point does Busbecq state this was the word used in Turkey, he simply states it was used by the "Turks". On his way to Constantinople Busbecq states he travelled through Hungary and used Hungarian guides. Until recent times "Turk" was a common term when referring to Hungarians. The word "tulipan" is in fact the Hungarian word for tulip. As long as one recognizes "Turk" as a reference to Hungarians, no amount of speculation is required to reconcile the word's origin or form. Busbecq was simply repeating the word used by his "Turk/Hungarian" guides.

The Hungarian word "tulipan" may be adopted from an Indo-Aryan reference to the tulip as a symbol of resurrection, "tala" meaning bottom or underworld and "pAna" meaning defence. Prior to arriving in Europe the Hungarians, and other Finno-Ugrians, embraced the Indo-Iranian cult of the dead, Yima/Yama, and would have been familiar with all of its symbols including the tulip.

Distribution and habitat

Tulips are mainly distributed along a band corresponding to latitude 40° north, from southeast of Europe ( Greece, Albania, North Macedonia, Kosovo, Southern Serbia, Bulgaria, most part of Romania, Ukraine, Russia) and Turkey in the west, through the Levant (Syria, Israel, Palestinian Territories, Lebanon and Jordan) and the Sinai Peninsula. From there it extends eastwards through Jerevan, (Armenia) and Baku ( Azerbaijan) and on the eastern shore of the Caspian Sea through Turkmenistan, Bukhara, Samarkand and Tashkent (Uzbekistan), to the eastern end of the range in the Pamir-Alai and Tien-Shan mountains in Central Asia, which form the centre of diversity. Further to the east, ''Tulipa'' is found in the western Himalayas, southern Siberia, Inner Mongolia, and as far as the northwest of China. While authorities have stated that no tulips west of the Balkans are native, subsequent identification of '' Tulipa sylvestris'' subsp. ''australis'' as a native of the Iberian peninsula and adjacent North Africa shows that this may be a simplification. In addition to these regions in the west tulips have been identified in Greece, Cyprus and the Balkans. In the south, Iran marks its furthest extent, while the northern limit is Ukraine. Although tulips are also throughout most of the Mediterranean and Europe, these regions do not form part of the natural distribution. Tulips were brought to Europe by travellers and merchants from Anatolia and Central Asia for cultivation, from where they escaped and naturalised (''see map''). For instance, less than half of those species found in Turkey are actually native. These have been referred to as neo-tulipae.

Tulips are indigenous to mountainous areas with temperate climates, where they are a common element of steppe and winter-rain Mediterranean vegetation. They thrive in climates with long, cool springs and dry summers. Tulips are most commonly found in meadows, steppes and chaparral, but also introduced in fields, orchards, roadsides and abandoned gardens.

Ecology

'' Botrytis tulipae'' is a major fungal disease affecting tulips, causing cell death and eventually the rotting of the plant. Other pathogens include anthracnose, bacterial soft rot, blight caused by '' Sclerotium rolfsii'', bulb nematodes, other rots including blue molds, black molds and mushy rot.

The fungus '' Trichoderma viride'' can infect tulips, producing dried leaf tips and reduced growth, although symptoms are usually mild and only present on bulbs growing in glasshouses.

Variegated tulips admired during the Dutch tulipomania gained their delicately feathered patterns from an infection with the tulip breaking virus, a mosaic virus that was carried by the green peach aphid, ''Myzus persicae''. While the virus produces fantastically streaked flowers, it also weakens plants and reduces the number of offsets produced. Dutch growers would go to extraordinary lengths during tulipomania to make tulips break, borrowing alchemists’ techniques and resorting to sprinkling paint powders of the desired hue or pigeon droppings onto flower roots.

Tulips affected by the mosaic virus are called "broken"; while such plants can occasionally revert to a plain or solid colouring, they will remain infected and have to be destroyed. Today the virus is almost eradicated from tulip growers' fields. The multicoloured patterns of modern varieties result from breeding; they normally have solid, un-feathered borders between the colours.

Tulip growth is also dependent on temperature conditions. Slightly germinated plants show greater growth if subjected to a period of cool dormancy, known as vernalisation. Furthermore, although flower development is induced at warmer temperatures (), elongation of the flower stalk and proper flowering is dependent on an extended period of low temperature (< ). Tulip bulbs imported to warm-winter areas are often planted in autumn to be treated as annuals.

The colour of tulip flowers also varies with growing conditions.

Cultivation

History

Islamic World

Cultivation of the tulip began in Iran ( Persia), probably in the 10th century. Early cultivars must have emerged from hybridisation in gardens from wild collected plants, which were then favoured, possibly due to flower size or growth vigour. The tulip is not mentioned by any writer from antiquity, therefore it seems probable that tulips were introduced into Anatolia only with the advance of the Seljuks. In the Ottoman Empire, numerous types of tulips were cultivated and bred, and today, 14 species can still be found in Turkey. Tulips are mentioned by Omar Kayam and Jalāl ad-Dīn Rûmi. Species of tulips in Turkey typically come in red, less commonly in white or yellow. The Ottoman Turks had discovered that these wild tulips were great changelings, freely hybridizing (though it takes 7 years to show colour) but also subject to mutations that produced spontaneous changes in form and colour.

A paper by Arthur Baker reports that in 1574, Sultan Selim II ordered the Kadi of A‘azāz in Syria to send him 50,000 tulip bulbs. However, John Harvey points out several problems with this source, and there is also the possibility that tulips and hyacinth (''sümbüll''), originally Indian spikenard (''Nardostachys jatamansi'') have been confused. Sultan Selim also imported 300,000 bulbs of ''Kefe Lale'' (also known as Cafe-Lale, from the medieval name Kaffa, probably ''Tulipa schrenkii'') from Kefe in Crimea, for his gardens in the Topkapı Sarayı in Istanbul.

It is also reported that shortly after arriving in Constantinople in 1554, Ogier Ghislain de Busbecq, ambassador of the Austrian Habsburgs to the court of Suleyman the Magnificent, claimed to have introduced the tulip to Europe by sending a consignment of bulbs west. The fact that the tulip's first official trip west took it from one court to the other could have contributed to its ascendency.

Sultan Ahmet III maintained famous tulip gardens in the summer highland pastures (''Yayla'') at Spil Dağı above the town of Manisa. They seem to have consisted of wild tulips. However, of the 14 tulip species known from Turkey, only four are considered to be of local origin, so wild tulips from Iran and Central Asia may have been brought into Turkey during the Seljuk and especially Ottoman periods. Also, Sultan Ahmet imported domestic tulip bulbs from the Netherlands.

The gardening book ''Revnak'ı Bostan'' (Beauty of the Garden) by Sahibül Reis ülhaç Ibrahim Ibn ülhaç Mehmet, written in 1660 does not mention the tulip at all, but contains advice on growing hyacinths and lilies. However, there is considerable confusion of terminology, and tulips may have been subsumed under hyacinth, a mistake several European botanists were to perpetuate. In 1515, the scholar Qasim from Herat in contrast had identified both wild and garden tulips (lale) as anemones (''shaqayq al-nu'man''), but described the crown imperial as ''laleh kakli''.

In a Turkic text written before 1495, the Chagatay Husayn Bayqarah mentions tulips (''lale''). Babur, the founder of the Mughal Empire, also names tulips in the Baburnama. He may actually have introduced them from Afghanistan to the plains of India, as he did with other plants like melons and grapes.

In Moorish Andalus, a "Makedonian bulb" (''basal al-maqdunis'') or "bucket-Narcissus" (''naryis qadusi'') was cultivated as an ornamental plant in gardens. It was supposed to have come from Alexandria and may have been Tulipa sylvestris, but the identification is not wholly secure.

Introduction to Western Europe

Although it is unknown who first brought the tulip to Northwestern Europe, the most widely accepted story is that it was Oghier Ghislain de Busbecq, an ambassador for Emperor Ferdinand I to Suleyman the Magnificent. According to a letter, he saw "an abundance of flowers everywhere; Narcissus, hyacinths and those in Turkish called Lale, much to our astonishment because it was almost midwinter, a season unfriendly to flowers." However, in 1559, an account by Conrad Gessner describes tulips flowering in Augsburg, Swabia in the garden of Councillor Heinrich Herwart. In Central and Northern Europe, tulip bulbs are generally removed from the ground in June and must be replanted by September for the winter. It is doubtful that Busbecq could have had the tulip bulbs harvested, shipped to Germany and replanted between March 1558 and Gessner's description the following year. Pietro Andrea Mattioli illustrated a tulip in 1565 but identified it as a narcissus.

Carolus Clusius is largely responsible for the spread of tulip bulbs in the final years of the 16th century; he planted tulips at the Vienna Imperial Botanical Gardens in 1573. He finished the first major work on tulips in 1592 and made note of the variations in colour. After he was appointed the director of the Leiden University's newly established Hortus Botanicus, he planted both a teaching garden and his private garden with tulips in late 1593. Thus, 1594 is considered the date of the tulip's first flowering in the Netherlands, despite reports of the cultivation of tulips in private gardens in Antwerp and Amsterdam two or three decades earlier. These tulips at Leiden would eventually lead to both the tulip mania and the tulip industry in the Netherlands. Over two raids, in 1596 and in 1598, more than one hundred bulbs were stolen from his garden.

Tulips spread rapidly across Europe, and more opulent varieties such as double tulips were already known in Europe by the early 17th century. These curiosities fitted well in an age when natural oddities were cherished and especially in the Netherlands, France, Germany and England, where the spice trade with the East Indies had made many people wealthy. ''Nouveaux riches'' seeking wealthy displays embraced the exotic plant market, especially in the Low Countries where gardens had become fashionable. A craze for bulbs soon grew in France, where in the early 17th century, entire properties were exchanged as payment for a single tulip bulb. The value of the flower gave it an aura of mystique, and numerous publications describing varieties in lavish garden manuals were published, cashing in on the value of the flower. An export business was built up in France, supplying Dutch, Flemish, German and English buyers. The trade drifted slowly from the French to the Dutch.

Between 1634 and 1637, the enthusiasm for the new flowers in Holland triggered a speculative frenzy now known as the tulip mania that eventually led to the collapse of the market three years later. Tulip bulbs had become so expensive that they were treated as a form of currency, or rather, as futures, forcing the Dutch government to introduce trading restrictions on the bulbs. Around this time, the ceramic tulipiere was devised for the display of cut flowers stem by stem. Vases and bouquets, usually including tulips, often appeared in Dutch still-life painting. To this day, tulips are associated with the Netherlands, and the cultivated forms of the tulip are often called "Dutch tulips". The Netherlands has the world's largest permanent display of tulips at the Keukenhof.

The majority of tulip cultivars are classified in the taxon '' Tulipa ×gesneriana''. They have usually several species in their direct background, but most have been derived from '' Tulipa suaveolens'' (today often regarded as a synonym with ''Tulipa schrenkii''). ''Tulipa ×gesneriana'' is in itself an early hybrid of complex origin and is probably not the same taxon as was described by Conrad Gessner in the 16th century.

The UK's National Collection of English florists' tulips and Dutch historic tulips, dating from the early 17th century to c.1960, is held by Polly Nicholson at Blackland House, near Calne in Wiltshire.

Introduction to the United States

It is believed the first tulips in the United States were grown near Spring Pond at the Fay Estate in Lynn and Salem, Massachusetts. From 1847 to 1865, Richard Sullivan Fay, Esq., one of Lynn's wealthiest men, settled on located partly in present-day Lynn and partly in present-day Salem. Mr. Fay imported many different trees and plants from all parts of the world and planted them among the meadows of the Fay Estate.

Propagation

The Netherlands is the world's main producer of commercial tulip plants, producing as many as 3 billion bulbs annually, the majority for export.

"Unlike many flower species, tulips do not produce nectar to entice insect pollination. Instead, tulips rely on wind and land animals to move their pollen between reproductive organs. Because they are self-pollinating, they do not need the pollen to move several feet to another plant but only within their blossoms."

Tulips can be propagated through bulb offsets, seeds or micropropagation. Offsets and tissue culture methods are means of asexual propagation for producing genetic clones of the parent plant, which maintains cultivar genetic integrity. Seeds are most often used to propagate species and subspecies or to create new hybrids. Many tulip species can cross-pollinate with each other, and when wild tulip populations overlap geographically with other tulip species or subspecies, they often hybridise and create mixed populations. Most commercial tulip cultivars are complex hybrids, and often sterile.

Offsets require a year or more of growth before plants are large enough to flower. Tulips grown from seeds often need five to eight years before plants are of flowering size. To prevent cross-pollination, increase the growth rate of bulbs and increase the vigour and size of offsets, the flower and stems of a field of commercial tulips are usually topped using large tractor-mounted mowing heads. The same goals can be achieved by a private gardener by clipping the stem and flower of an individual specimen. Commercial growers usually harvest the tulip bulbs in late summer and grade them into sizes; bulbs large enough to flower are sorted and sold, while smaller bulbs are sorted into sizes and replanted for sale in the future.

Because tulip bulbs don't reliably come back every year, tulip varieties that fall out of favour with present aesthetic values have traditionally gone extinct. Unlike other flowers that do not suffer this same limitation, the Tulip's historical forms do not survive alongside their modern incarnations.

Horticultural classification

In horticulture, tulips are divided into fifteen groups (Divisions) mostly based on flower morphology and plant size.
*Div. 1: Single early – with cup-shaped single flowers, no larger than across. They bloom early to mid season. Growing tall.
*Div. 2: Double early – with fully double flowers, bowl shaped to across. Plants typically grow from tall.
*Div. 3: Triumph – single, cup shaped flowers up to wide. Plants grow tall and bloom mid to late season.
*Div. 4: Darwin hybrid – single flowers are ovoid in shape and up to wide. Plants grow tall and bloom mid to late season. This group should not be confused with older Darwin tulips, which belong in the Single Late Group below.
*Div. 5: Single late – cup or goblet-shaped flowers up to wide, some plants produce multi-flowering stems. Plants grow tall and bloom late season.
*Div. 6: Lily-flowered – the flowers possess a distinct narrow 'waist' with pointed and reflexed petals. Previously included with the old Darwins, only becoming a group in their own right in 1958.
*Div. 7: Fringed (Crispa) – cup or goblet-shaped blossoms edged with spiked or crystal-like fringes, sometimes called “tulips for touch” because of the temptation to “test” the fringes to see if they are real or made of glass. Perennials with a tendency to naturalize in woodland areas, growing tall and blooming in late season.
*Div. 8: Viridiflora
*Div. 9: Rembrandt
*Div. 10: Parrot
*Div. 11: Double late – Large, heavy blooms. They range from tall.
*Div. 12: Kaufmanniana – Waterlily tulip. Medium-large creamy yellow flowers marked red on the outside and yellow at the centre. Stems tall.
*Div. 13: Fosteriana (Emperor)
*Div. 14: Greigii – Scarlet flowers across, on stems. Foliage mottled with brown.
*Div. 15: Species or Botanical – The terms "species tulips" and "botanical tulips" refer to wild species in contrast to hybridised varieties. As a group they have been described as being less ostentatious but more reliably vigorous as they age.
*Div. 16: Multiflowering – not an official division, these tulips belong in the first 15 divisions but are often listed separately because they have multiple blooms per bulb.

They may also be classified by their flowering season:
*Early flowering: Single Early Tulips, Double Early Tulips, Greigii Tulips, Kaufmanniana Tulips, Fosteriana Tulips,
*Mid-season flowering: Darwin Hybrid Tulips, Triumph Tulips, Parrot Tulips
*Late season flowering: Single Late Tulips, Double Late Tulips, Viridiflora Tulips, Lily-flowering Tulips, Fringed (Crispa) Tulips, Rembrandt Tulips

Neo-tulipae

A number of names are based on naturalised garden tulips and are usually referred to as neo-tulipae. These are often difficult to trace back to their original cultivar, and in some cases have been occurring in the wild for many centuries. The history of naturalisation is unknown, but populations are usually associated with agricultural practices and are possibly linked to saffron cultivation. Some neo-tulipae have been brought into cultivation, and are often offered as botanical tulips. These cultivated plants can be classified into two Cultivar Groups: 'Grengiolensis Group', with picotee tepals, and the 'Didieri Group' with unicolourous tepals.

Horticulture

Tulip bulbs are typically planted around late summer and fall, in well-drained soils. Tulips should be planted apart from each other. The recommended hole depth is deep, and is measured from the top of the bulb to the surface. Therefore, larger tulip bulbs would require deeper holes. Species tulips are normally planted deeper.

Culture and politics

Iran

The celebration of Persian New Year, or Nowruz, dating back over 3,000 years, marks the advent of spring, and tulips are used as a decorative feature during the festivities.

A sixth-century legend, similar to the tale of ''Romeo and Juliet'', tells of tulips sprouting where the blood of the young prince Farhad spilt after he killed himself upon hearing the (deliberately false) story that his true love had died.

The tulip was a topic for Persian poets from the thirteenth century. The poem '' Gulistan'' by Musharrifu'd-din Saadi, described a visionary garden paradise with "The murmur of a cool stream / bird song, ripe fruit in plenty / bright multicoloured tulips and fragrant roses...". In recent times, tulips have featured in the poems of Simin Behbahani.

The tulip is the national symbol for martyrdom in Iran (and Shi'ite Islam generally), and has been used on postage stamps and coins. It was common as a symbol used in the 1979 Islamic Revolution, and a red tulip adorns the flag redesigned in 1980. The sword in the centre, with four crescent-shaped petals around it, create the word "Allah" as well as symbolising the five pillars of Islam. The tomb of Ayatollah Ruhollah Khomeini is decorated with 72 stained glass tulips, representing 72 martyrs who died at the Battle of Karbala in 680CE. It was also used as a symbol on billboards celebrating casualties of the 1980–1988 war with Iraq.

The tulip also became a symbol of protest against the Iranian government after the presidential election in June 2009, when millions turned out on the streets to protest the re-election of Mahmoud Ahmadinejad. After the protests were harshly suppressed, the Iranian Green Movement adopted the tulip as a symbol of their struggle.

The word for tulip in Persian is "laleh" (لاله), and this has become popular as a girl's name. The name has been used for commercial enterprises, such as the Laleh International Hotel, as well as public facilities, such as Laleh Park and Laleh Hospital, and the tulip motif remains common in Iranian culture.

In other countries and cultures

Tulips are called ''lale'' in Turkish (from Persian: "laleh" لاله). When written in Arabic letters, "lale" has the same letters as ''Allah'', which is why the flower became a holy symbol. It was also associated with the House of Osman, resulting in tulips being widely used in decorative motifs on tiles, mosques, fabrics, crockery, etc. in the Ottoman Empire. The tulip was seen as a symbol of abundance and indulgence. The era during which the Ottoman Empire was wealthiest is often called the Tulip era or ''Lale Devri'' in Turkish.

Tulips became popular garden plants in the east and west, but, whereas the tulip in Turkish culture was a symbol of paradise on earth and had almost a divine status, in the Netherlands it represented the briefness of life.

In Christianity, tulips symbolise passion, belief and love. White tulips represent forgiveness while purple tulips represent royalty, both important aspects of Easter. In Calvinism, the five points of the doctrines of grace have been summarized under the acrostic TULIP.

By contrast to other flowers such as the coneflower or lotus flower, tulips have historically been capable of genetically reinventing themselves to suit changes in aesthetic values. In his 1597 herbal, John Gerard says of the tulip that “nature seems to play more with this flower than with any other that I do know”. When in the Netherlands, beauty was defined by marbled swirls of vivid contrasting colours, the petals of tulips were able to become "feathered" and "flamed". However, in the 19th century, when the English desired tulips for carpet bedding and massing, the tulips were able to once again accommodate this by evolving into “paint-filled boxes with the brightest, fattest dabs of pure pigment”. This inherent mutability of the tulip even led the Ottoman Turks to believe that nature cherished this flower above all others.

Seventeenth-century tulip mania has been described above.

'' The Black Tulip'' (1850) is an historical romance by Alexandre Dumas, père. The story takes place in the Dutch city of Haarlem, where a reward is offered to the first grower who can produce a truly black tulip.

The tulip occurs on a number of the Major Arcana cards of occultist Oswald Wirth's deck of Tarot cards, specifically the Magician, Emperor, Temperance and the Fool, described in his 1927 work ''Le Tarot, des Imagiers du Moyen Âge''.

Tulip festivals

Tulip festivals are held around the world, for example in the Netherlands and Spalding, England. There is also a popular festival in Morges, Switzerland. Every spring, there are tulip festivals in North America, including the Tulip Time Festival in Holland, Michigan, the Skagit Valley Tulip Festival in Skagit Valley, Washington, the Tulip Time Festival in Orange City and Pella, Iowa, and the Canadian Tulip Festival in Ottawa, Ontario, Canada. Tulips are also popular in Australia and several festivals are held in September and October, during the Southern Hemisphere's spring. The Indira Gandhi Memorial Tulip Garden hosts an annual tulip festival which draws huge attention and has an attendance of over 200,000.

Consumption

Tulip petals are edible flowers. The taste varies by variety and season, and is roughly similar to lettuce or other salad greens. Some people are allergic to tulips.

Tulip bulbs look similar to onions, but should not generally be considered food. The toxicity of bulbs is not well-understood, nor is there an agreed-upon method of safely preparing them for human consumption. There have been reports of illness when eaten, depending on quantity. During the Dutch famine of 1944–45, tulip bulbs were eaten out of desperation, and Dutch doctors provided recipes.

Animals

As with other plants of the lily family, tulips are poisonous to domestic animals including horses, cats and dogs. In cats, ingestion of small amounts of tulips can include vomiting, depression, diarrhea, hypersalivation, and irritation of the mouth and throat, and larger amounts can cause abdominal pain, tremors, tachycardia, convulsions, tachypnea, difficulty breathing, cardiac arrhythmia, and coma. All parts of the tulip plant are poisonous to cats, while the bulb is especially dangerous. A veterinarian should be contacted immediately if a cat has ingested tulip.
