A young man in Dong Nai Province, southern Vietnam, has used self-taught crossbreeding to differentiate the adenium—called the "desert rose" (a flowering succulent, locally Su)—into several hundred varieties, selling roughly 200 pots a day. What cannot be overlooked in this story reported by Vietnamese agricultural media is that he holds up export as his next aim and clearly cites Japan as a market example. Among farm products, flowers and ornamental plants face high quarantine hurdles, and for Japanese horticultural-materials makers and plant importers, the question is whether they can make contact before supply ramps up in earnest. We dig into what the Japanese side can prepare at the "eve" stage, as the region begins to move.
200 pots a day, several hundred varieties—what a Dong Nai crossbreeding grower is setting in motion
According to reports, the grower is Nguyen Van Nhat. The location is Xuan Bac in Dong Nai city, corresponding to Suoi Nho in the former Dinh Quan district. He grows adeniums on a garden of about 3,000 square meters, with roughly 30,000 plants. He has set out a plan to expand to 100,000 plants in the future.
The varieties produced by crossbreeding number in the hundreds, with the signature variety being "Suoi Nho su," which has deep pink with silver-white edging. When the market is good, about 200 pots sell a day, at unit prices of VND 50,000–200,000 per pot (about 300–1,200 yen at about 60 yen per VND 10,000). Ones with distinctive, rare flower features are said to reach VND 2–3 million (about 12,000–18,000 yen). It is also mentioned that he imports parent plants from Thailand, Tanzania, and Taiwan as seed stock for variety creation.
Nhat says, "No two crossbred adeniums have the same-looking flower. To be chosen by enthusiasts, a new variety must be distinctive and rare," and voices his pride that "Vietnamese farmers' crossbreeding skills are by no means inferior to those of other countries." Placing the uniqueness of the variety itself as the source of product value sets him apart from ordinary mass-production flower growers.
The substance of "wanting to export"—why Japan was named
Notable is the mention of export. Nhat says he is "advancing a plan to grow and export adeniums," and the article cites as assumed markets "markets with a tropical climate, or communities that love ornamental plants," listing as concrete examples Thailand, Taiwan, Japan, and some European countries. That Japan was named can be read as reflecting a recognition that it is a market with a large population of succulent and foliage-plant enthusiasts and a high willingness to pay for rare varieties.
Behind this is the growth of the market as a whole. According to Vietnam's cultivation and plant-protection authority (Cuc Trong trot va Bao ve thuc vat), the country's flower export value has already surpassed the US$100 million mark (about 15.5 billion yen at about 155 yen per dollar). It is a small figure compared with fruit or seafood, but high-unit-price ornamental plants are an item that "earns even in small volumes," leaving room for small crossbreeding growers to take on the world.
| Item | Reported content | Approximate yen conversion |
|---|---|---|
| Cultivated area | About 3,000 m² | — |
| Number of plants | About 30,000 plants (plan to expand to 100,000) | — |
| Daily sales | About 200 pots | — |
| Standard unit price | VND 50,000–200,000/pot | About 300–1,200 yen |
| Rare varieties | VND 2–3 million/pot | About 12,000–18,000 yen |
| Vietnam's flower export value | Over US$100 million | Over about 15.5 billion yen |

The "plant quarantine" wall standing in the way before reaching the Japanese market
What is worth viewing calmly here is the difficulty of bringing live plants into Japan. Even if the Vietnamese side speaks of an "export plan," the pots must clear the barrier of plant quarantine before they line up in Japanese consumers' hands. For imports of live plants, a phytosanitary certificate issued by the exporting country's government must be attached, and upon arrival they undergo inspection at a plant-protection station. If pests or diseases are confirmed, they become subject to disinfection or disposal.
The item most likely to become a barrier is soil. Japan strictly restricts imports of live plants with soil, and soil clinging to the roots is regarded as a route of entry for pests and diseases. Sending them potted as is is hard to envisage, and practical responses such as washing the roots to remove soil, or switching to a sterile growing medium, become realistic points of discussion. For some items and genera, cultivation-site inspection or isolation quarantine may be required, and the domestic strength of "it sells high because it is a rare variety" does not directly translate into ease of passing through export.
This structure closely resembles fruit exports to Japan. The trend of demanding regional transparency and traceability is A national system that tracks durian by QR and The standardization of Dong Thap fruit, with region codes brought down to the farmer level pointing in the same direction as these moves. For ornamental plants too, building a system that can show which garden grew them and who did so is expected to eventually become a prerequisite for trade.
A "get-ahead point of contact" for Japanese horticultural-materials makers and importers
Precisely because supply is still at the planning stage, the Japanese side has time to prepare. We organize the implications here by type of business.
Plant importers and specialty garden shops
Rare adenium varieties are goods sold on "the variety's face," not on volume. Since they tend to be small-volume, high-unit-price spot transactions rather than full container lots, it is worth locking in at an early stage a region that can meet quarantine requirements. Whether a region's crossbreeding skills are the real thing can only be judged by actually exchanging samples of parent plants and seedlings. A farmer who makes "variety uniqueness" his weapon, like Nhat, can also be a counterpart for exclusive-handling negotiations.
Horticultural-materials and production-technology makers
Looking ahead to export, soilless cultivation and the switch to sterile growing media are unavoidable. Here there is room for Japanese makers of growing media, rockwool, pot materials, irrigation control, and the like to enter. Providing a region that "wants to sell to Japan" with the cultivation materials and technology to pass Japanese quarantine, as a set—making contact in this order creates a relationship beyond mere materials sales. The idea of earning through small-volume, high-added-value Ha Tinh's Korean melons, running three crops a year on 500 m² also resonates with this case, and the smaller the farmer, the more open they are to externally sourcing materials and technology.
D2C and foliage-plant brands
The domestic foliage-plant and succulent boom is pushing up demand for rare varieties. Being able to handle a Vietnamese "crossbred variety found only here," brand story and all, becomes a differentiator for breaking out of price competition. Being able to clearly show that it is a legitimate import that passed quarantine is itself a backing of trust.
Ripple effects on the market—will "flowers" become the next frontier of agricultural exports?
When it comes to Vietnamese farm products for Japan, seafood, coffee, and fruit have been the leads so far. Flowers and ornamental plants are still at a US$100 million scale, a small presence in the context of agricultural exports as a whole. But because of the high unit prices and the nature of value being determined by an individual's crossbreeding skills, it is a field where even a few people on a small area can take on the international market. If a region like Dong Nai can establish a template for quarantine and quality control, there is every possibility that flowers will follow the "standardization → export to Japan" path that fruit has walked.
The question for Japanese businesses is simple. Do you move to purchase once supply is in place, or do you get involved in how the region grows now, at the planning stage, by bringing in cultivation materials and quarantine-response know-how? Only companies that can choose the latter will secure the juiciest part—variety uniqueness.
Summary: move now, while no one is buying yet
The adeniums the young man in Dong Nai grows are, for now, merely something that sells 200 pots a day within Vietnam. But the fact that he himself named Japan as an export destination is a clear signal for Japan's horticulture industry. As a next action, it is worth starting now—horticultural-materials makers by preparing a proposal that packages "soilless cultivation + passing quarantine," and plant importers by listing candidate regions that can meet quarantine requirements and sounding out sample transactions. Once the buying competition begins, the window to unique varieties may already have been secured by other companies.
