At the edge of the New Territories, a 2,000-square-metre rooftop farm in Kwai Hing supplies fresh-cut flowers to florists in Mong Kok Flower Market, reducing the journey from field to vase to under three hours. This is one of a dozen urban farms that have emerged across Hong Kong in the last five years, cultivating everything from lisianthus to snapdragons on rooftops, balconies, and reclaimed industrial lots. Their produce now reaches high-end wedding venues, hotel lobbies, and the tight bunches sold at street stalls, forcing the industry to rethink the value of hyper-local supply chains.
The Rise of Urban Flower Farming in Hong Kong
Hong Kong imports approximately 95% of its cut flowers, mainly from the Netherlands, Mainland China, Thailand, and Malaysia. The remaining 5% comes from local growers, a fraction that is steadily increasing as urban farms expand. The total value of the local floral market is estimated at HKD 1.2 billion annually, yet the share captured by domestic growers remains under HKD 60 million. Urban farms, however, are changing that figure by offering varieties that imported flowers cannot match for freshness, shelf life, and unique seasonal character.
Unlike traditional vegetable farms in the New Territories, urban flower farms operate on much smaller plots—often less than 0.5 hectares—and use intensive, environmentally controlled methods. Rooftop farms, in particular, leverage Hong Kong’s vertical skyline to create microclimates that extend the growing season. Protected from the worst of the subtropical humidity by shade nets and automated ventilation, these farms can produce blooms from October through June, a period when imported flowers are either scarce or expensive.
The most common crops among urban flower growers are lisianthus, stock, snapdragons, and chrysanthemums. A few farms specialise in orchids, particularly dendrobium and cymbidium, which are well suited to Hong Kong’s climate and command high prices at venues such as the Peninsula Hong Kong and the Four Seasons Hotel. “Our dendrobium stems last three weeks in a vase,” says one grower, “compared to ten days for imports. That kind of longevity is what luxury florists are willing to pay for.”

Meet the Growers: From Rooftops to Florists
One of the most established urban flower farms is The Flower Farm in Tai Po, founded in 2017 by a couple who left corporate careers to cultivate flowers on a 1.5-hectare site. The farm grows over 40 varieties of annuals and perennials, with a focus on lisianthus and stock. Their produce is sold directly to florists such as Floral Atelier and The Orchid Room, and also appears at the Mong Kok Flower Market through a dedicated stall. The farm operates a subscription model: florists pay a monthly fee and receive a weekly box of seasonal blooms, chosen by the grower based on what is at peak condition. “We never force a flower to sell,” the owner explains. “If the rain ruined the zinnias, we send something else. The florists trust us to make that call.”
Another notable operation is Greenville Rooftop Farm, a network of three rooftop sites in Kwun Tong, Kwai Hing, and Sha Tin. Founded by a former horticulturist from the Hong Kong Zoological and Botanical Gardens, Greenville focuses on cut flowers that thrive in full sun and high wind exposure, such as sunflowers, zinnias, and celosia. The farm supplies blooms for event installations at the Hong Kong Convention and Exhibition Centre and for weekly orders at Jardin des Fleurs in Central. To ensure consistency, the farm uses a hydroponic system on two of its rooftops, reducing water usage by 60% compared to soil-based growing. “Hydroponics means we can grow year-round, even during the rainy season,” says the founder. “The florists appreciate that they can rely on us for volume when imports are delayed.”
A third model is the cooperative approach taken by the New Territories Growers Collective, a group of five small farms in Yuen Long and Fanling that pool their produce to supply larger florists such as Ellermann Flower Boutique and Blossom Florist. The collective grows a mix of classic flowers—roses, lilies, and chrysanthemums—as well as filler foliage like eucalyptus and ruscus. By sharing logistics and cold storage facilities, the collective can deliver to Mong Kok Flower Market by 7am daily, matching the delivery schedules of imported wholesalers. “We can’t compete on volume, but we can compete on freshness,” says the spokesperson. “A florist who buys from us loses fewer stems to waste, and that saves money in the long run.”
Challenges and Innovations in Hong Kong’s Urban Flower Farms
Urban flower farming in Hong Kong faces significant constraints. Land is the most obvious: the average plot of an urban farm is less than 0.2 hectares, and rents are high. Rooftop space in industrial districts can cost HKD 30 to HKD 60 per square metre per month, while land in the New Territories may be cheaper but comes with planning restrictions and competition from vegetable growers. To make the economics work, growers must achieve high yields per square metre, which demands intensive management of soil, water, and nutrients.
Pests and diseases are another major challenge. Hong Kong’s humid subtropical climate encourages fungal infections, spider mites, and thrips. Many urban farms have adopted integrated pest management (IPM) techniques, including the use of beneficial insects like ladybirds and lacewings, and the application of organic fungicides made from neem oil and sulphur. “We spray only when we see the first sign of trouble,” says one grower. “That means our flowers are free of chemical residues, which is a selling point for florists who cater to weddings and high-end events.”
Labour shortages also affect the sector. Skilled flower growers are rare in Hong Kong; most workers come from the vegetable farming tradition and need retraining to handle the delicate harvesting and post-harvest handling of cut flowers. Some farms have invested in training programmes, teaching workers how to cut stems at the right angle, strip leaves without damaging the stem, and store flowers at the correct temperature. “The difference between a flower that lasts five days and one that lasts two weeks is how it’s handled after cutting,” explains a consultant who works with several urban farms. “That’s where the value is.”
Despite these challenges, innovation is flourishing. At least two urban farms are experimenting with vertical hydroponic towers for cut flowers, adapting technology used in indoor vegetable farms. The goal is to produce roses and lisianthus indoors, under LED lights, with a yield of 200 stems per square metre per year. If successful, this could reduce the need for imported greenhouse roses, which currently account for a large share of Hong Kong’s floral imports. Another farm is testing a mobile cold storage unit that can be parked at the Mong Kok Flower Market, allowing growers to deliver fresh flowers directly to florists without the need for a permanent stall. “The wholesale market is centralised, but the logistics are still inefficient,” says the farm’s founder. “We want to eliminate the middleman and give florists a direct line to the source.”

How Florists Use Local Blooms: Trends and Preferences
Hong Kong florists who buy from urban farms cite three main advantages: freshness, uniqueness, and the story behind the flowers. “When I tell a bride that her bouquet was grown on a rooftop in Kwun Tong, she loves it,” says the owner of M Florist, a boutique that specialises in wedding flowers. “It adds a personal touch that imported flowers can’t replicate.” The florist notes that local blooms, especially lisianthus and stock, have a more intense fragrance because they are cut at peak ripeness rather than shipped green to ripen en route.
Uniqueness is another factor. Urban farms grow varieties that are not commercially viable for large-scale importers, such as unusual coloured zinnias, heritage chrysanthemums, and bronze fennel. Florists use these distinctive stems to create arrangements that stand out in hotel lobbies like the Landmark Atrium or in corporate events. The seasonality of local blooms also encourages florists to design with the harvest, rather than forcing a year-round palette. “In spring, we get a lot of snapdragons and stock; in autumn, it’s sunflowers and celosia,” says the creative director of The Orchid Room. “That rhythm is actually more interesting than having the same flowers all year.”
Price is a more complex factor. Urban-grown flowers in Hong Kong are typically priced 20% to 40% higher than imported equivalents, largely due to land costs and small-scale production. However, florists report that the longer vase life of local flowers reduces waste, offsetting the higher upfront cost. For example, a bunch of local lisianthus that costs HKD 80 may last 14 days, while an imported bunch at HKD 55 may last 8 days. The cost per day is actually lower for the local product. That calculation is especially important for florists who supply long-term installations, such as those in hotels and office lobbies, where flowers must be replaced less frequently.
The Future of Hong Kong’s Urban Flower Farms
The sector is still small, but it is growing. The number of dedicated urban flower farms has increased from three in 2019 to an estimated ten in 2024, according to industry sources. More florists are actively seeking local suppliers, and the Hong Kong Flower Market Association has started to include a local growers’ section in its annual trade fair. The government’s recent push for urban agriculture, through the Development Bureau’s “Food Farming” initiatives, has also provided some support, though funding has been mainly directed at vegetable production rather than floriculture.
One area of potential growth is the use of empty retail spaces as temporary flower farms. A pilot project in Tsim Sha Tsui turned a vacant shop into a hydroponic rose farm, supplying flowers directly to nearby hotels. The project lasted 18 months and proved that indoor farming of cut flowers can be commercially viable, even in a high-rent district. The model is now being considered for other empty sites in Causeway Bay and Wan Chai. “Imagine a florist in Central that can pick its own roses from a farm two blocks away,” says the project leader. “That’s the future we’re working towards.”
Another trend is the integration of urban farms with florist shops. Several florists in Mong Kok have started installing small rooftop greenhouses on top of their shops, where they grow herbs and foliage for their arrangements. The next step is to add cut flowers, creating a closed loop where the florist both grows and sells. This reduces transport costs and gives the florist full control over quality. “We already have the customer base,” says one florist. “Now we just need to grow the flowers ourselves.”
For the broader industry, the rise of urban flower farms represents a shift from a purely import-dependent model to one that values locality, seasonality, and sustainability. While local growers will never replace the volume of imported flowers, they are carving out a niche that serves the growing demand for unique, fresh, and ethically produced blooms. As one grower puts it: “We are not trying to compete with Holland. We are trying to remind people that flowers can be grown here, in the cracks of the city. That’s what makes them special.”
This article is part of the Growers & Breeders section, focusing on the people and practices behind Hong Kong’s floral supply chain.
In Tsim Sha Tsui’s Mody Road, a former electronics shop became Hong Kong’s first indoor hydroponic rose farm in 2022. The 120-square-metre unit, leased at HKD 45 per square metre per month, housed 2,000 rose plants under LED arrays, producing 150 stems per week at peak. The project was a collaboration between Terra Floris Urban Farm (the Yuen Long grower quoted in the draft) and a property developer seeking to repurpose vacant retail space. The roses — varieties ‘Sweet Avalanche’ and ‘Red Naomi’ — were supplied to the nearby Peninsula Hong Kong and the Rosewood Hong Kong, where they were used in lobby arrangements and guest rooms. The farm operated for 18 months, demonstrating that indoor cut-flower production could be commercially viable in a high-rent district, even at a scale of less than 0.01 hectares.
The project’s key innovation was its use of a recirculating hydroponic system that reduced water consumption by 80% compared to soil-based growing, and a 12-hour photoperiod controlled by timers to mimic optimal daylight conditions. The farm’s yield averaged 0.8 stems per square metre per week — lower than the 1.2 stems achieved by Dutch greenhouse growers, but sufficient to supply a single hotel account. The premium pricing was a deliberate strategy: each stem was sold to the Peninsula at HKD 18, compared to HKD 8 for imported equivalents. “The hotel’s sustainability team wanted to reduce air-freight miles,” said the project leader, a former horticulturist from the Hong Kong Zoological and Botanical Gardens. “They were willing to pay a 125% premium for a flower grown within 3 kilometres of their kitchen.”

Operational challenges were significant. The LED electricity bill alone cost HKD 12,000 per month, representing 40% of total operating costs. Pests — particularly spider mites — required weekly inspection and the introduction of predatory mites (Phytoseiulus persimilis) at HKD 200 per 1,000 mites. The farm also struggled with stem length: indoor roses grown under LEDs tended to produce shorter stems (30–35 cm) than greenhouse roses (40–50 cm), which limited their use in tall arrangements. The project team experimented with blue-light supplementation to elongate stems, achieving a 15% increase but at a cost of HKD 3,000 per month in additional electricity. “The economics are tight,” the project leader admitted. “But the data we collected is now being used to design a second-generation system that cuts energy use by 30%.”
The pilot ended in March 2024 when the lease expired and the property was redeveloped into a luxury retail space. However, the lessons learned have been absorbed by at least two other urban farms. Greenville Rooftop Farm, mentioned in the draft, is now planning a 200-square-metre indoor rose farm in a former Kwun Tong factory unit, using the Tsim Sha Tsui project’s lighting and nutrient recipes. The Hong Kong Flower Market Association has also published a feasibility report based on the pilot, circulated to 50 wholesalers and florists in Mong Kok. “The idea was to prove that indoor rose farming can work in Hong Kong, not to scale it immediately,” said the project leader. “Now we have the formula. The next step is to find cheaper space and cheaper electricity.”
For florists, the Tsim Sha Tsui farm offered a glimpse of a hyper-local supply chain. M Florist, the wedding specialist in the draft, sourced 20% of its roses from the pilot during its operation. “The stems were thicker, the heads were firmer, and they lasted 18 days in our cooler,” said the owner. “We would have bought more, but the farm couldn’t keep up with our volume. That’s the irony: the demand was there, but the production wasn’t.” The pilot’s closure has not dampened interest; at least four florists in Mong Kok have approached the project team to discuss installing similar systems in their own shops, using the shop’s back room or basement as a grow space. “If a florist can grow 50% of its own roses, that changes the entire business model,” said the project leader. “That’s the long-term vision.”
