To the naked eye, the delicate velvet roses in southeastern Turkey appear black and overwhelm the senses with their irresistible sweet smell.
The rosebuds are just as dark, and when fully developed, the flower takes on the color of an intensely rich red wine.
These black roses, known as "Karagül" in Turkish and thornier than others, can only grow in the town of Halfeti with soil that has distinctive features including a special pH level.
The unique color cannot be preserved elsewhere, experts say.
Now, Halfeti's residents want to transform the rose into a brand since Turkey's rose sector is a blooming business.
The industry is currently dominated by the western province of Isparta, known as Turkey's "rose garden."
Today, Turkey and Bulgaria make up around 80% of the world's rose oil production.
But Halfeti resident Devrim Tutuş, 28, has already seen business flourish.
After coming up with a business plan to promote the black roses, he now supplies Istanbul with petals for colognes, Turkish delight and ice cream.
Demand is already outgrowing supply.
That doesn't stop Tutuş who already has his next plan: Karagül wine.
"There's a huge market out there in Istanbul. It's all about Isparta roses. Why not the same here?" he said.
The black rose's fortunes were not always so sweet.
It once aroused only indifference among residents, said a local official in charge of preserving the roses.
"They were everywhere in the gardens but nobody paid attention to them," said his friend who only gave his name as Bülent.
"Locals had no idea the roses were unique. We transported some to higher ground and started black rose production in greenhouses," said the official, who did not wish to be named.
In upper Halfeti, one greenhouse operated by the town's agriculture department is home to 1,000 roses.
But the town's residents rallied to rescue the rose after a dam on the Euphrates River flooded the region in the early 2000s, threatening to bury the flower. The construction of the Birecik Dam in 2000 was part of a series of development projects in southeast Turkey.
Today, 20 variants of black roses have been identified worldwide – including 16 in Turkey, said botanist Ali Ikinci.
"Karagül is not an endemic species in Halfeti," Ikinci, a professor at Harran University in Şanlıurfa province, said.
"But the particular ecology, climate and soil cause it to bloom darker there. If you plant that rose somewhere else, it won't be as dark or black."
The professor insisted Halfeti's rose was "unique."
The color of the rose darkens, becoming more black and the scent is stronger as one moves from Şanlıurfa – where Halfeti is – toward Syria, which is 60 kilometers (38 miles) to the south, Ikinci said.
The Halfeti official explained the rose blossoms on higher ground because the soil close to the dam is more acidic because of the Euphrates' waters.
Ikinci believes the origins of Karagül could be the "Louis XIV" black rose, grown in France in 1859 and named after the French king.
But Frederic Achille, deputy director of the Botanical Gardens of the Museum of Natural History in Paris, isn't too sure.
"'Louis XIV' could really be transformed by the waters of the Euphrates... and bogus communication," he said with a smile.
Halfeti is also home to the peculiar green rose that has the appearance of a weed, but it is real and not just photoshopped by avid Instagram users.
"It remains mysterious. Some locals had it in their gardens. But because it's odorless, it failed to attract attention," Ikinci said.
The green flower was "just a curiosity in rose gardens" after it was introduced in Europe in 1856 by British nurseries, Achille added.
But that won't stop Halfeti from taking advantage of its real and hidden treasures.
By the shores of the dam, a few amateur gardeners promote the black rose to tourists alongside boat tours to see the caves, now underwater.
