From Kenyan lakesides to Dutch greenhouses, global growers face a climate that no longer cooperates with their business models
Every morning, somewhere on Earth, a truck loaded with roses, marigolds, or tulips is racing against a clock that has nothing to do with traffic. Cut flowers begin dying the moment they’re severed from the plant. They must be cooled, graded, boxed, flown, auctioned, and sold — often within 48 hours — before they wilt into worthlessness. It is one of the most weather-dependent, time-sensitive trades on the planet, built on the assumption that certain places will always have the right amount of sun, the right amount of rain, and nights just cool enough to keep petals from bruising.
That assumption is breaking down. From the shores of a Kenyan lake to the wholesale stalls beneath a Kolkata bridge, the same story keeps repeating with different flowers and different accents: rainfall has stopped behaving, heat has stopped staying in its season, and the people who grow and sell the world’s flowers are having to relearn a business their families may have run for generations.
KENYA: WHEN THE LAKE CAME FOR THE ROSES
For decades, the shores of Lake Naivasha, in Kenya’s Great Rift Valley, seemed almost engineered for growing roses. The altitude tempers the equatorial sun; the freshwater lake offers irrigation; the day length barely changes year-round. Out of this narrow strip of land grew an industry that now supplies roughly 40 percent of the roses sold in the European Union and generated more than 81 billion Kenyan shillings in export earnings in 2025 alone, supporting well over 150,000 jobs, many of them held by women.
But the lake that made the industry possible has turned against it. Since 2011, Lake Naivasha has been rising in fits and surges that scientists call the “rising lakes” phenomenon, driven by shifting rainfall and warming temperatures across the Rift Valley. It isn’t a single flood but a slow siege: greenhouse by greenhouse, the water advances and doesn’t retreat. Researchers tracking the shoreline say the lake has swallowed as much as three-quarters of some flower farms’ land.
Dickson Ngome knows exactly what that looks like. He leased a small plot near the lake in 2008, when the shore was more than two kilometers away and farmers worried the lake might vanish entirely. Instead, the water crept closer year after year. In late 2025, after a rainy season that started early and refused to let up, Ngome and his family woke one morning to find their home and farm sitting inside the lake, everything under nearly a foot of water. Thousands of others along the shoreline have been displaced the same way, and in the same season, farm managers elsewhere on the lake watched, week by week, as four greenhouses of blooms disappeared beneath the rising water — the highest levels some farms had ever recorded.
The irony is bitter: an industry once threatened by drought fears is now being drowned by rain nobody predicted. Growers are responding by relocating greenhouses to higher ground, investing in flood barriers, and lobbying for better water-level forecasting — but as one Kenyan researcher put it, the lake does not wait for anyone’s five-year plan.
THE ANDES: ROSES BRED FOR A CLIMATE THAT NO LONGER HOLDS STILL
Fly northwest across the Atlantic, over the flower districts outside Bogotá and up into the volcanic highlands around Quito, and you find the source of most of the roses sold in North America. Here, at altitudes above 2,500 meters, warm days and cool nights have historically produced roses so structurally perfect — thick stems, huge blooms, extraordinary vase life — that Ecuadorian and Colombian growers built a $1.4 billion-plus export industry almost entirely on the strength of their microclimate.
That microclimate is no longer as dependable as the brochures suggest. In 2024, an intense El Niño weather pattern flipped the Andes’ usual rainfall on its head: torrential rain lashed Colombia and Ecuador’s Pacific coast while the high savannas on the other side of the mountains dried out, part of a drought so severe that Ecuador was forced to ration electricity and Colombia’s capital faced water restrictions. Growers who had spent a century optimizing for one kind of weather now had to manage both drought stress and erratic downpours in the same growing cycle — sometimes within the same month.
Industry analysts who track the region describe growers who over-pruned their rose bushes into near-dormancy in one crisis, only to scramble to bring the same plants back into full production for the next demand surge, a process that cannot be rushed because rose bushes recover on their own physiological timeline, not the market’s. Layer in “weather extremes” on top of that whiplash, and the loading docks in Quito and Bogotá — which now handle tens of thousands of tons of flowers in the two weeks before Mother’s Day alone — are increasingly gambling on logistics windows that a single unexpected storm can close.
Growers here haven’t abandoned ship; if anything, they’ve expanded, planting new hectares of roses in Ecuador even as informal growers rush in to meet demand. But expansion built on a shifting foundation is a different kind of risk than expansion built on stability, and everyone in the trade — from the pruning crews to the air-cargo companies now moving record tonnages of flowers each spring — is quietly aware the ground beneath the industry, climatically speaking, is no longer as fixed as the mountains that hold it up.
INDIA: THE HEAT THAT TURNS MARIGOLDS TO GOLD
Long before refrigerated trucks and auction floors, there was the flower market — the kind that opens before dawn, spreads along a riverbank or under a bridge, and runs on nothing but reputation and haggling. Kolkata’s Mallick Ghat market, sprawled beneath the Howrah Bridge for more than 130 years, is one of the largest of these markets anywhere in the world, its narrow lanes thick with roses, lotus, tuberose, and above all, the marigolds that saturate Hindu ritual life — from temple offerings to wedding garlands to funeral wreaths. More than two thousand vendors work here daily, arriving by truck from growing villages an hour or two outside the city.
Markets like this are acutely, almost violently, sensitive to weather, because they run on same-day freshness and next-to-no cold storage. A late monsoon, a sudden heat spike, or an unseasonal downpour doesn’t just bruise a shipment — it can wipe out a day’s income for thousands of small vendors at once.
Six hundred miles south, in Bengaluru’s iconic KR Market, that vulnerability played out in vivid, immediate numbers one week in early 2024, when a brutal heatwave collided with the city’s ongoing water crisis just as two major festivals — Ugadi and Eid — fell days apart. Jasmine, the flower most in demand for the occasion, jumped from around 300 rupees a kilogram to 600 almost overnight. Roses doubled in price. Longtime vendors, some of whom had worked the market for three decades, said plainly that the heat and the water shortage had throttled the harvest just as demand spiked, and there simply weren’t enough blooms to go around. A year that saw better rains told the opposite story: with crop yields up, jasmine prices for the same festival season fell by half within a single day, as growers finally had enough water and cool nights to bring a full crop to market at once.
Multiply that whiplash across India’s dozens of regional flower markets, most of which serve religious and cultural occasions on fixed calendar dates that cannot be postponed for weather, and you get an entire ritual economy improvising in real time every time the monsoon arrives early, late, or not at all.
THE NETHERLANDS: A CLIMATE BUILT INDOORS, AND ITS HIDDEN WEAK SPOT
If the flower markets of Kenya, the Andes, and India are exposed to the sky, the Netherlands built an industry that seemed to escape it. Around Aalsmeer, just south of Amsterdam, the Royal FloraHolland flower auction moves more than 40 million stems a day through a warehouse roughly the size of two hundred football fields — flowers arriving from more than 60 countries, sorted, priced by a descending-price “Dutch auction” clock, and shipped onward within hours. Much of what fuels this system isn’t grown under open sky at all, but inside vast climate-controlled greenhouses that use artificial lighting and heating to manufacture a perfect, endless spring regardless of what’s actually happening outside.
That engineered independence turned out to have its own weather-shaped vulnerability, just one step removed from the fields. When Russia’s invasion of Ukraine sent European natural gas prices soaring to twenty times their normal level in 2022, Dutch greenhouse growers — who depend on gas-fired heating to keep tulips, roses, and orchids growing through cold, dark winters — found themselves unable to afford the very climate control that had made their business possible. Grower Ruud van der Lans made the unprecedented decision to switch off the lights in 80 percent of his greenhouses that winter simply to survive the bill. Industry groups estimated that up to 40 percent of the country’s roughly 3,000 greenhouse businesses were in financial distress, and the number of growers abandoning the trade altogether more than doubled that year, cutting roughly 100 million euros from the country’s annual flower production almost overnight.
It was a reminder that even an industry built to defeat the weather with steel and glass is still, at bottom, an energy-intensive way of substituting for a stable climate — and that when the underlying systems that make artificial climates affordable become unstable themselves, the greenhouse offers no real shelter. In response, some Dutch growers have poured tens of millions of euros into geothermal heating and biomass plants, treating energy diversification as its own kind of climate adaptation, alongside newer efforts to recycle up to 90 percent of the water used across the sector.
A BUSINESS BUILT ON BORROWED WEATHER
What connects a flooded rose farm in the Rift Valley, a drought-stressed hillside outside Quito, a heatwave in a Bengaluru market, and a gas crisis in a Dutch greenhouse is the same underlying fact: the modern flower trade was built by identifying the handful of places on Earth where weather happened to be nearly perfect for growing delicate, fast-perishing crops, and then betting an entire global logistics network on that weather staying put. Valentine’s Day and Mother’s Day, the two biggest days on the floral calendar, now depend on cargo planes lifting off on schedule from Bogotá, Quito, and Nairobi, which in turn depend on harvests timed to the day, which in turn depend on rainfall and temperature patterns that used to be reliable enough to plan a business around.
They no longer are, uniformly. Growers everywhere are adapting in the ways available to them — moving greenhouses to higher ground in Kenya, diversifying rose varieties bred for heat and drought tolerance in the Andes, building better water storage in Indian growing villages, and chasing energy independence in Dutch greenhouses. None of it is a permanent fix; all of it is an admission that the old assumption — that the sky would simply keep cooperating — no longer holds.
For the vendor at Mallick Ghat sorting marigolds at dawn, or the farmer paddling a boat past his flooded greenhouse on Lake Naivasha, the flower trade was never really about flowers. It was about borrowing a very specific, very fragile kind of weather and turning it into a livelihood. The bill for that loan is coming due in every growing region on Earth, one unpredictable season at a time.
