When people think of the International Horticultural Expo, they may imagine spectacular flower gardens, impressive international pavilions, or picturesque spots perfect for taking photos. Yet, behind these world-class exhibition lies a story spanning more than 70 years—one that has evolved from showcasing horticultural excellence to exploring how humanity and nature can thrive together.

Born from a Vision of Postwar Renewal (1948)
Emerging after World War II, with the Netherlands and the International Association of Horticultural Producers (AIPH) playing key roles, international horticultural exhibitions supported agricultural recovery, environmental restoration, and community well-being. Over time, they evolved from showcasing horticultural innovation to promoting greener cities and a stronger connection between people and nature.
