No challenge is too big for GMF.
It started with a spark: encounters with exotic mushroom producers in South Korea, and an ambitious idea — bring unique, high-quality mushrooms to the European market, and control every step yourself.

The journey begins
Two brothers arrive in the Netherlands — the perseverance forged then still runs through everything GMF does.
Green Mushroom Farm
Founded after encounters with exotic mushroom producers in South Korea; the European specialty range begins.
From one farm to five countries
What began as one person's dream grew into a family enterprise, connecting nurseries across Kosovo, Germany, South Korea, England and the Netherlands.
20 years, complete control
Own farms, own grading, own logistics — a closed loop from cultivation to delivery, 365 days a year.
Complete chain control
From production to the customer.
GMF manages the entire supply chain — from cultivation to delivery — partnering with major European retailers through innovative marketing strategies. Nothing is outsourced that we can control ourselves.
Own farms
Hirano Mushroom in Kosovo — a pioneer of Japanese-method shiitake production — and Mushroom Park GmbH in Germany. Central European locations mean mushrooms reach destinations across the continent in peak condition.
Own grading
Every crate is graded to spec before it ships — wild mushrooms twice, once at the point of picking and again at our Rotterdam hub. Consistency is a discipline, not an accident.
Own logistics
We invest in the future of mushrooms by playing a leading role in education and research — mushrooms picked today are on a truck tonight and on a European shelf tomorrow.
Gateway to Europe
Fast delivery, anywhere.
Headquartered in De Lier — minutes from Rotterdam, Europe's largest port. That single fact underwrites the whole business: daily routes across the Netherlands, Germany, Belgium and France, and scheduled routes to Scandinavia and beyond, all from one hub.
Teaching & research
Always innovating.
We invest in the future of mushrooms by playing a leading role in education and research — cooperating with research facilities worldwide to obtain and share knowledge.
