It has a beautiful yellow flower, a taste somewhere between artichoke and potato, dozens of names across different countries, and a remarkable history.
“Topinambur, known worldwide as Jerusalem artichoke, is one of those crops that humanity periodically forgets and then rediscovers. Today it is returning not as a ‘vegetable from the past,’ but as a zero-waste, environmentally friendly and economically attractive crop for farmers and processors,” says Kateryna Zvierieva, Development Director of the Ukrainian Horticulture Association (UHA).
And the most interesting part – this “Jerusalem artichoke” has absolutely nothing to do with Jerusalem.
Why “Jerusalem” if it comes from America?
The story behind the name could be a plot for a gastronomic novel. The homeland of topinambur is North America, where Indigenous peoples cultivated and consumed it long before Europeans arrived, EastFruit reports. The plant reached Europe in the early 17th century thanks to the French lawyer and traveler Marc Lescarbot, who brought tubers from Canada to France.
In France, the plant was named topinambour, after the Brazilian Tupinambá tribe, whose representatives were touring Europe at the time in ethnographic exhibitions. The French simply attached an exotic name to a new vegetable.
“But the Italian version is even more elegant. In Italy, topinambur was called girasole, meaning ‘sunflower,’ because the plant resembles one. When the word girasole entered English usage, it gradually transformed into ‘Jerusalem.’ That is how Jerusalem artichoke was born – a name with neither artichoke nor Jerusalem in its biography,” explains Kateryna Zvierieva.
From a marketing perspective, it was brilliant. Historically – pure coincidence. In Italy, some farms have managed to increase profitability through processing topinambur and actively promoting it via professional media.
From poor man’s food to delicacy
The history of topinambur in Europe has been contradictory. In the 17th–18th centuries, it was widely grown as an alternative to potatoes. However, once potatoes became a mass crop, topinambur was quickly displaced – it was considered “too simple,” “rural,” and later even “food for hard times.”
In the 20th century, it resurfaced during wars and crises, when farmers needed quick harvests with minimal inputs. Then it was forgotten again.
Only in the 21st century has topinambur unexpectedly returned in a new role: a niche restaurant product, functional food ingredient, raw material for processing, and even an energy crop.
Today it appears on restaurant menus in Italy, France, and Germany in the form of risotto, cream soups, and chips; in organic food stores; in the pharmaceutical and nutraceutical industries; and in biofuel and green energy projects.

The secret: Inulin and “smart” carbohydrates
The main biochemical feature of topinambur is its high inulin content. Unlike starch, inulin is a special carbohydrate that does not cause sharp spikes in blood sugar, functions as a prebiotic (feeding beneficial gut microbiota), and is widely used in functional foods and dietary supplements.
For this reason, topinambur is often called “a vegetable for people who care about their health,” particularly in the context of diabetes management, weight control, microbiome restoration, and nutrition during recovery after stress or illness.
One important note: due to its high fiber content, it may cause bloating in sensitive individuals, similar to other prebiotic-rich foods.
A zero-waste crop: everything Is marketable
From an economic perspective, topinambur is close to an ideal crop.
1. Tubers
Fresh market sales, processing, freeze-drying, powders, syrups, chips, frozen products, purées, and food industry ingredients.
2. Above-ground biomass
Stems and leaves are used for biofuel pellets, biogas, bioethanol, and compost. One hectare of topinambur can produce at least 10 tons of dry shredded stem biomass.
“In practice, this is a crop with dual economics: tubers can be sold on the market, while the above-ground part can be processed into pellets and used as fuel. In this case, winter heating costs can be reduced almost to zero,” the expert notes.
3. Environmental benefits
Topinambur absorbs more CO₂ than many traditional crops, helps purify air in industrial zones, is used for the reclamation of contaminated soils, and requires minimal pesticide application. Essentially, it is a rare example of a crop where nearly every part – from root to stem – can be monetized.
Geography of new demand
Today, topinambur is back “on the global map”:
“In Italy, topinambur is actively cultivated in the Veneto and Piedmont regions, with stable domestic demand from restaurants and exports to Germany. In Germany and Austria, there is a well-developed organic and functional food market where topinambur has found its niche. In France, it remains a traditional gastronomic product. In China and the United States, research and bioenergy projects are underway using this crop. Meanwhile, in Eastern Europe, interest in topinambur is growing as a niche export crop and processing raw material. In Ukraine, farmers are exploring opportunities for cooperation in cultivation and marketing,” notes the Development Director of the Ukrainian Horticulture Association.
In many countries, topinambur is no longer viewed as an “exotic,” but rather as a strategic crop – not mass-market, yet high-margin.
Why farmers are looking at It again
Topinambur is attractive where farmers need:
- low production costs;
- climate resilience;
- minimal chemical inputs;
- the ability to grow without strict crop rotation;
- multiple market channels simultaneously.
“But there is a key factor farmers always mention – topinambur starts generating real income only when there is sufficient volume and processing. One farmer with one hectare is an exotic case. Cooperation, contracts with processors, and export channels – that’s already a business,” Kateryna emphasizes.
Practice shows that niche crops become profitable faster where producers invest not only in cultivation but also in promotion: product branding, packaging, market communication, retail engagement, and media visibility.
A vegetable of the past or a crop of the future?
Topinambur is a rare example of a plant that has survived colonial times, wars and famine, neglect, and has returned in the era of sustainable development.
Today it is valued not for its exotic nature, but for its economics, environmental benefits, and versatility.
The story of the “Jerusalem artichoke” also makes it an ideal product for storytelling – with a legend, distinctive taste, and real market potential.
In a world where agriculture increasingly seeks crops with a low carbon footprint and high added value, topinambur looks less like nostalgia and more like a logical component of the agribusiness of the future.
For producers, processors, and companies in the fruit and vegetable sector, success today depends not only on cultivation technology but also on proper market positioning, partnership development, and demand creation.
