Dutch Tulipmania - Is there a Black Tulip?

I've read that in spite of the best efforts of Dutch horticulturists they still have failed to develop the elusive truly black tulip. I wonder if this is really true - anyone know for sure?

A BIT ABOUT DUTCH TULIPMANIA
The Dutch have long had a fascination with the tulip, which came to Holland from Turkey via Vienna. A 16th-century Austrian ambassador to the Ottoman Empire brough back to Vienna some tulip bulbs from turkey and gave them to a friend, Carolus Clusius, the curator of the Austrian Emperor's medicinal garden.
Clusius later became the director of the University of Leiden's Botanical Gardens and brought some of the bulbs with him to Leiden and, in the fall of 1593, planted them in some nearby sandy fields that, being sheltered by the massive North Sea sand dunes, he speculated would then provide ideal tulip-growing conditions. When the bulbs sprouted the next spring to produce flowers, tulips were on their way to becoming an overnight sensation; aristorcrats clamored after the bulbs, whose possession was a sign of prestige. The Tulipmania that struck in the 1630s pushed the cost of buls to dizzying heights, with single bulbs of some rare varieties being sold to eager speculators for huge sums of money. In one publicized case, a single Semper Augustus bulb sold for $2,250 (a fortune at the time) plus a horse and carriage! A futures market in bulbs sprouted up to buy crops not even planted yet. In 1637, the tulip-bulb market crashed, wiping out the fortunes of many. Though bulb prices wilted, the national infatuation with the tulip did not, and the Dutch have ever since planted them in droves.
The tulip even helped save the lives of many Dutch during WWII as, after the German Army had requisitioned much of the Dutch farm harvest, the Dutch, during the "Hunger Winter" had to resort to eating tulip (and other flower) bulbs, which though bitteer made a nourishing soup
The tulip's lure and popularity was not confined to the Dutch and the flower's popularity spread far and wide. Holland's ideal bulb-growing conditions, added to the Dutch penchant for mercantilism, led to the development of many bulb farms and a domination of the international market, not only in tulips but in many other bulbs such as gladioluses and irises. Holland exports 6.5 billion bulbs annually, including 280 million to the States. bubls are produced by cutting the flowers off as soon as they indicate their color and are ascertained to be disease-free, leaving just the bald stem, a process that make bigger bulbs. Dutch flower researchers are constantly adding new and improved variites. the long awaited breakthrough to produce a black ulip is as yet, however, elusive and the search goes on.
The word tulip is derived from the Turkish word "tulebend" ("turban") as the tulip bloom was thought to look like a Turkish turban.
(This is from an article i wrote years ago and now would like to know the status of the black tulip - i've heard to some claim to have done it - please say what you know. Thanks!)
