Tulip (Tulipa) is a genus of about 100 species of flowering plants in the family Liliaceae. They are native to southern Europe, north Africa, and Asia from Anatolia and Iran (where the flower is suggested on the nation's flag) east to northeast China and Japan. The centre of diversity of the genus is in the Pamir and Hindu Kush mountains and the steppes of Kazakhstan.
They are perennial bulbous plants growing to 10-70 cm tall, with a small number of strap-shaped, waxy-textured, usually glaucous green leaves and large flowers with six tepals. The fruit is a dry capsule containing numerous flat disc-shaped seeds.
Unofficially, the flower is also emblematic of The Netherlands. For instance, in an annual gesture of gratitude to Canada for liberating the nation from Nazi German tyranny in World War II and for serving as a refuge for the Crown Princess (subsequently Queen Juliana), a supply of tulips is sent to be planted in Canada's national capital in Ottawa.
In both the Ottoman Empire and Netherlands, separate episodes of tulip mania struck both countries which both led to damaging speculation crashes which also contributed to the Ottoman Empire's financial decline.
Numerous cultivars have been bred for garden use. It is often considered one of humanity's "canonical flowers", along with the rose, lily, orchid, and peony (Pollan, M).
Some historical cultivars have had a striped, "feathered", "flamed", or variegated flower, as in the illustration. While some modern varieties also display multicoloured patterns, this results from a natural change in the upper and lower layers of pigment in the tulip flower. Historical variegated varieties- such as those admired in the Dutch tulipomania gained their delicately feathered patterns from a viral infection. The mosaic virus is carried by peach potato aphids, Myzus persicae, an insect common in European gardens of the seventeenth century, in which peach trees were often a prominent feature. While the virus produces fantastically beautiful flowers, it also causes the plant to sicken and die slowly. Today, it has been almost completely eradicated from growers' fields. The Black Tulip was the title of a historical romance by Alexandre Dumas (1850), in which the city of Haarlem has a reward outstanding for the first grower who can produce a truly black tulip. This fascination with growing a black tulip, a task biologically impossible, was historically accurate to the tulipomania in which the novel is set.
Tulips can be grown in either of two ways: through offsets or seed. Being genetic clones of the parent plant, offsets are the only way to enlarge the stock of a given tulip cultivar. By contrast, tulips do not come true from seed; the mixing of genes between parent tulips is very unpredictable. A tulip grown from seed will usually bear only a passing resemblance to the flower from which the seeds were taken. This makes for great potential in breeding new tulip flowers, and great variation in the wild. However, tulip growers must be patient: offsets often take at least a year to grow to sufficient size to flower, and a tulip grown from seed will not flower for anywhere between five and seven years after planting. "Broken" tulips (tulips affected by the mosaic virus) will occasionally revert to plain "breeder" colouring, but usually maintain their colourful, infected state when grown from offsets.
Regardless of how the flower originally arrived in Europe, its popularity soared quickly. Charles de L'Ecluse (Clusius) is responsible for much of the spread of tulip bulbs in the final years of the sixteenth century. He was the author of the first major work on tulips, finally completed in 1592. Clusius had already begun to note and remark upon the diseased variations in colour that made the tulip so admired. His taste for tulips quickly spread to others. While occupying a chair in the medical faculty of the University of Leiden, Clusius planted both a teaching garden and his own private plot with tulip bulbs. In 1596 and 1598, however, Clusius suffered thefts from his garden, with over a hundred bulbs stolen in a single raid. Between 1634 and 1637, the early enthusiasm for the new flowers triggered a speculative frenzy now known as the tulip mania and tulip bulbs were then considered a form of currency. The Netherlands and tulips are still associated with one another. The term 'Dutch tulips' is often used for the cultivated forms.
Tulip Festivals are held in the Netherlands and in North America every May. Tulips are now also popular in Australia, and several festivals are held during September and October in the Southern Hemisphere's spring.
