A global flower industry built on stable climates now confronts erratic weather, rising lakes, and shifting seasons that threaten Valentine’s Day bouquets, wedding garlands, and centuries-old traditions.
The dread arrives before dawn. For flower farmers worldwide, it comes not as fire or flood—events that at least announce themselves—but as something subtler: a degree too warm through the night, a millimeter of rain at the wrong hour, a frost three weeks early or a rainy season that never arrives. Flowers, in the most literal sense, are weather made visible. Their color, stem length, and fragrance are instructions written by temperature, light, and water. For millennia, growers read those instructions and answered them. Over the past two decades, those instructions have started to contradict themselves.
This story travels from Kenya’s Rift Valley to the Andes, from Dutch tulip fields to Indian marigold plots, from California’s fire-prone coast to Japan’s cherry blossom groves. In each place the crop differs—roses, tulips, marigolds, ranunculus, chrysanthemums—but the underlying plot repeats: a climate that flower farming was built around is no longer the climate that shows up.
Kenya’s Lake Naivasha: From Drought to Deluge
Lake Naivasha sits ninety minutes from Nairobi’s airport, close enough that a rose cut Tuesday morning in Kenya stands in a London vase by Wednesday afternoon. More than fifty commercial farms line its shores, making Kenya one of the world’s top rose-exporting nations, sending flowers primarily to Europe, the United Kingdom, and increasingly South Korea.
For decades, the story was drought. Rose cultivation is famously water-intensive, requiring seven to thirteen liters per stem. In 2009, what Jane Ngiga, then chief executive of the Kenya Flower Council, called “the worst year in terms of drought, countrywide,” emptied lakes across the Rift Valley. Rivers that once fed Naivasha dried up entirely.
But since 2015, the opposite has occurred. The lake has been rising—not receding. Unusually heavy rains on the Aberdare mountain range have pushed water levels up year after year, startling scientists and devastating shoreline communities. Lina Jamwa of the Kenya Flower Council describes farms that have watched the lake advance onto their land, disrupting production. Some five thousand people were displaced in a single year.
“The volatility runs in both directions and on multiple fronts at once,” said Patrick Mbugua, general manager of Wildfire Flowers Kenya. “We’ve seen increased disease pressure due to unusual weather patterns—sometimes excessive hot weather, which sees a jump in pests, other times unusually low temperatures, which increases fungal infections.”
The economic stakes are enormous. Kenya’s flower sector employs more than half a million people directly and indirectly. Mohamed Adow, director of the Nairobi-based think tank Power Shift Africa, called the industry’s climate exposure “yet another example of the future we face if governments continue to let the climate crisis wreak havoc.”
Ethiopia’s Lake Ziway: A Mirror Image
Nine hundred miles north, a strikingly similar story unfolds around Lake Ziway in Ethiopia’s Rift Valley. Frank Ammerlaan, a second-generation Dutch rose grower, arrived in 2006 to found AQ Roses, which now exports more than one hundred million stems annually. The farm’s natural advantages—volcanic soils, equatorial light, reliable freshwater—once seemed unbeatable.
Those conditions are eroding. Lake Ziway has dropped by roughly a meter over two decades, its surface area shrinking eight percent since 2000. Fish populations have declined, surrounding wetlands have dried, and communities report growing water scarcity.
According to a 2024 analysis by Christian Aid, roughly fifty-nine percent of all internationally traded roses originate in just five Global South countries—Kenya, Ethiopia, Uganda, Ecuador, and Colombia—all confronting escalating extreme-weather risk.
Colombia and Ecuador: Freeze, Then Flood, Then Heat
Ecuador’s rose industry, centered on valleys north of Quito at 2,800 to 3,000 meters, depends on a narrow band of stable conditions: constant equatorial daylight, cool nights, intense highland sun.
Just across the border, Colombian growers have learned the hard way. In 2010, a severe cold snap struck weeks before Valentine’s Day—the single most important date on the global flower calendar, responsible for roughly twelve percent of Colombia’s annual sales. Workers scrambled to spray water over rose beds, releasing latent heat as the water froze to keep plants alive. It wasn’t enough.
“If you don’t do well in Valentine’s, it’s a lost year,” said Fernando Arenas of El Redil, using the industry’s own grim shorthand.
That same year brought the worst rainy season in sixty years, triggering flooding and fungal disease. By 2024, El Niño brought record-high temperatures and dry heat that pushed roses to bloom early, throwing off carefully timed harvest schedules.
“We need to harvest approximately fifteen percent of our whole year’s production in a ten to fifteen day period,” said Moises Croitoru, manager of Passion Growers. The logistical high-wire act leaves essentially no margin for a freeze, flood, or heatwave.
Dutch Tulips Drowning in Rain
Arjan Smit has spent his entire adult life among tulips in Spierdijk, North Holland, continuing a family business his grandfather started in 1940. His fields still produce the postcard image of red and pink ribbons stretching to the horizon, but the image is fraying.
“The climate has changed. We can feel that,” Smit said. “Last year, it was just raining, raining, raining. In total in our sector, we lost around eight to nine percent of the bulbs in the field. They were killed by water.”
Tulip bulbs require long, cold, dry winters. Without them, stems come up short and flowers emerge lopsided or fail to bloom. Yet winters are becoming milder and wetter, while spring heatwaves grow more frequent.
“When I started thirty years ago, we watered the fields two to four times in spring,” Smit said. “In the last ten years, sometimes we have to water every week—ten times. It’s much more expensive.”
The consequences rippled globally. The autumn of 2023 brought heavy rainfall delaying planting; spring rains and hailstorms compounded damage. Major wholesale supplier De Vroomen Garden Products reported sourcing only about eighty percent of the tulip bulbs the market required—a shortfall that grew to roughly thirty percent.
India’s Marigolds and the ‘Wet Drought’
In India, marigolds occupy a specific and sacred place: strung into garlands for weddings, temples, and festivals. Hundreds of thousands of smallholder farmers grow them as a secondary cash crop.
In autumn 2025, days of unseasonal rain destroyed large stretches of Maharashtra’s crop just as flowers approached festival-season harvest. Standing water turned blooms black; humidity spread fungal blight. “The flowers were just about to bloom when the rain came,” one grower reported. “Within a few hours, everything was destroyed.”
The same pattern recurred across India’s flower belt. In Punjab, hailstorms tied to shifting weather caused losses estimated at thirty-five percent for growers timing crops for the Baisakhi wedding season. Farmer Gurwinder Singh noted the particular cruelty: “Baisakhi is round the corner and considered auspicious for weddings.”
One farmer from Karmala coined a phrase capturing a distinctly modern crisis: “We appeal to the Chief Minister to declare a wet drought.” The old vocabulary of agricultural disaster—too much rain or too little—increasingly fails to describe conditions that combine the worst features of both.
California: Fire on the Central Coast
In December 2017, the Thomas Fire—one of California’s largest wildfires—swept toward Carpinteria, home to a cluster of flower farms at the foot of the Santa Ynez Mountains. Dani Hahn, owner of Rose Story Farm, watched firefighters set controlled backburns to stop the advancing blaze.
“We know we live in a desert climate and are prone to wildfires, but I don’t think anyone could expect the scope of this,” she said afterward. Her farm was scorched but largely spared.
Kasey Cronquist, then chief executive of the California Cut Flower Commission, noted the interruption to shipping: “These aren’t crops that can just hang on trees. It’s a very perishable product that needs to keep moving.” Rose Story Farm lost nearly a week of deliveries.
California’s subsequent decade has brought increasingly severe wildfire seasons, driven by prolonged drought and hotter temperatures—the same atmospheric shift responsible for flooding in Colombia, rising lakes in Kenya, and wet winters in the Netherlands.
Japan’s Cherry Blossoms: A 1,200-Year Record Broken
Not every disruption destroys crops. In Japan, climate change is rewriting one of the most closely watched natural calendars: cherry blossom season.
Tokyo’s cherry trees bloomed on average around March 29 between 1961 and 1990. By 1991–2020, that had shifted to March 24—roughly 1.2 days per decade earlier. In Kyoto, blossoms reached full bloom on March 26 in a recent year, ten days ahead of the historical average and the earliest since formal records began in 1953.
“Our studies have shown that the start of cherry blossom season is closely linked with the average temperature in February and March,” said Shunji Ambe of the Japan Meteorological Agency.
Elizabeth Wolkovich, an associate professor at the University of British Columbia, called Japan’s record “one of the most powerful available windows into the pace of planetary warming.” Projections suggest peak bloom could advance another full week by 2100.
Research on the warm winter of 2023–2024 found that Somei-Yoshino cherry trees on Hachijojima bloomed on the same date as trees 860 kilometers north—an equivalence attributed to shifting balance between cold exposure and subsequent heat. Models suggest these cherries could eventually stop flowering at the southern limits of their range.
China’s Flower Province: Frost Where Frost Shouldn’t Come
Yunnan province supplies roughly seventy percent of China’s commercially sold flowers, produced by an estimated eight hundred thousand farmers across seventy thousand hectares. Kunming carries the nickname “City of Eternal Spring,” built on mild year-round temperatures and 2,200 hours of annual sunshine.
In late November 2025, Yunnan experienced an unusually long rainy season followed by an early, severe frost. Temperatures fell to minus 2.2 degrees Celsius, with sub-zero readings inside greenhouses. Major growing districts reported extensive damage, hitting smaller growers hardest. Wholesale prices for some rose varieties rose by roughly twenty renminbi per bundle.
As one account of Yunnan’s floriculture sector noted: “A single late spring cold snap can cause heavy losses”—a sentence that could describe Naivasha’s rising lake, Colombia’s early freeze, or India’s blackened marigolds with equal accuracy.
What Growers Are Learning
No single story proves a planetary trend; flower farming has always been a gamble against weather. What is harder to dismiss is the pattern that emerges when these stories are stacked together: a Kenyan lake reversing direction, an Ethiopian lake shrinking, Colombian growers racing freezing temperatures one year and early blooms the next, a Dutch farmer watering ten times a season and still losing bulbs to rot, Indian farmers coining the term “wet drought,” a Californian farm scorched by wildfire, a cherry blossom record spanning twelve centuries broken repeatedly, a Chinese flower hub blindsided by frost.
Growers are adapting—solar power and crowd-financed irrigation in Kenya, biological pest control in Ecuador, drought-tolerant trials in Dutch gardens, fire-preparedness infrastructure in California, domestically bred climate-resilient varieties in Yunnan. None of these responses resolves the underlying problem.
What remains constant is the particular vulnerability of a flower: unlike grain, it cannot be stored; unlike livestock, it cannot be moved; and unlike almost any other commercial crop, its economic value depends on a narrow, ceremonial window—a wedding date, a religious festival, a single retail holiday—that does not move to accommodate the weather, even when the weather refuses to cooperate. That unforgiving combination makes the flower trade, perhaps more than any other form of agriculture, an early and unusually visible register of how much the climate has already begun to change.
