From Kenyan lakes to Dutch greenhouses, extreme weather reshapes a $100 billion trade built on perfect growing conditions
Every morning, a global network of trucks, cargo planes, and refrigerated warehouses races against an invisible deadline. Cut flowers begin dying the moment they are severed from their stems, leaving growers and shippers just 48 hours to cool, grade, package, auction, and deliver blooms before they lose all commercial value. This intricate system depends on an increasingly fragile assumption: that certain regions will always deliver the precise combination of sun, rain, and cool nights that produce perfect petals.
That assumption is collapsing across multiple continents simultaneously.
Kenya: Rising Waters Swallow the Rose Capital
Along the shores of Lake Naivasha in Kenya’s Great Rift Valley, an industry that supplies roughly 40 percent of the roses sold in the European Union is literally drowning. The lake, which once made the region ideal for rose cultivation with its reliable irrigation and stable equatorial climate, has been rising since 2011 in what scientists call the “rising lakes” phenomenon — a cascading effect of shifting rainfall patterns and warming temperatures.
Researchers tracking the shoreline estimate the lake has consumed up to three-quarters of some flower farms’ land. What once stood two kilometers from the water’s edge now sits beneath nearly a foot of water.
Dickson Ngome, a small-scale farmer who leased land near the lake in 2008, woke one morning in late 2025 to find his home and farm submerged after an early and relentless rainy season. He is among thousands displaced as the water advances greenhouse by greenhouse, never retreating.
The irony is stark: an industry once feared for drought now cannot escape floods. Growers are relocating greenhouses to higher ground and investing in flood barriers, but as one Kenyan researcher observed, the lake does not wait for anyone’s five-year plan.
The Andes: Microclimates Unravel Under El Niño
In the volcanic highlands above 2,500 meters near Quito and Bogotá, growers who supply most of North America’s roses find their legendary microclimate turning erratic. These high-altitude zones historically produced roses with thick stems and extraordinary vase life, supporting a combined export industry worth more than $1.4 billion.
In 2024, a powerful El Niño flipped normal rainfall patterns. Torrential rain struck Colombia and Ecuador’s Pacific coast while the high savannas on the mountains’ eastern slopes dried out. Ecuador faced electricity rationing; Colombia’s capital imposed water restrictions. Growers who spent a century optimizing for one weather regime suddenly managed drought stress and erratic downpours within the same growing cycle — sometimes the same month.
Industry analysts describe growers who over-pruned rose bushes into near-dormancy during one crisis, only to scramble for production when demand surged. Rose bushes recover on their own physiological timeline, not the market’s. With weather extremes compounding that whiplash, loading docks handling tens of thousands of tons of flowers in the two weeks before Mother’s Day alone increasingly gamble on logistics windows that a single unexpected storm can close.
India: Heatwaves Devastate Religious Flower Markets
Beneath Kolkata’s Howrah Bridge, Mallick Ghat market has operated for more than 130 years, its narrow lanes thick with marigolds, roses, lotus, and tuberose. More than 2,000 vendors arrive daily from villages an hour or two outside the city, selling flowers that saturate Hindu ritual life — temple offerings, wedding garlands, funeral wreaths.
These markets run on same-day freshness with almost no cold storage. A late monsoon, sudden heat spike, or unseasonal downpour can wipe out a day’s income for thousands of small vendors at once.
In early 2024, Bengaluru’s KR Market experienced that vulnerability in stark numbers. A brutal heatwave combined with the city’s water crisis just as two major festivals — Ugadi and Eid — fell days apart. Jasmine, the flower most in demand, jumped from roughly 300 rupees per kilogram to 600 rupees overnight. Roses doubled in price. Longtime vendors reported that heat and water shortages throttled harvests just as demand spiked.
When better rains returned the following year, 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 full crops to market simultaneously.
The Netherlands: Energy Crisis Exposes Indoor Farming’s Weakness
The Royal FloraHolland auction in Aalsmeer moves more than 40 million flower stems daily through a warehouse the size of 200 football fields. Much of this system relies on climate-controlled greenhouses that use artificial lighting and heating to manufacture perfect growing conditions year-round.
That engineered independence revealed its vulnerability when Russia’s invasion of Ukraine sent European natural gas prices soaring to twenty times normal levels in 2022. Dutch greenhouse growers, who depend on gas-fired heating through cold, dark winters, found themselves unable to afford the climate control their business required.
Grower Ruud van der Lans made the unprecedented decision to switch off lights in 80 percent of his greenhouses to survive winter energy bills. Industry groups estimated up to 40 percent of the country’s roughly 3,000 greenhouse businesses faced financial distress. The number of growers abandoning the trade more than doubled that year, cutting roughly 100 million euros from annual flower production almost overnight.
Some Dutch growers have since invested tens of millions of euros in geothermal heating and biomass plants, treating energy diversification as a new form of climate adaptation alongside efforts to recycle up to 90 percent of water used across the sector.
A Global Trade Built on Borrowed Weather
What connects a flooded rose farm in Kenya, a drought-stressed hillside in Ecuador, a heatwave in Bengaluru, and a gas crisis in Dutch greenhouses is the same underlying reality: the modern flower trade identified the handful of places on Earth with nearly perfect growing conditions and bet an entire global logistics network on that weather remaining stable.
Valentine’s Day and Mother’s Day, the two biggest floral holidays, now depend on cargo planes lifting off on schedule from Bogotá, Quito, and Nairobi — which depends on harvests timed to the day, which depends on rainfall and temperature patterns that used to be reliable enough to build a business around.
Growers everywhere are adapting: moving greenhouses to higher ground in Kenya, breeding heat-tolerant rose varieties in the Andes, building better water storage in Indian villages, and chasing energy independence in the Netherlands. None of it offers a permanent fix.
For the vendor sorting marigolds beneath Howrah Bridge at dawn, or the farmer paddling 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 now coming due, one unpredictable season at a time.
