About Horticultural Expos

International Horticultural Exhibitions, also known as Horticultural Expos, are the largest (50 ha minimum) International Exhibitions covering all aspects of Horticulture.

Article 4 of the 1928 Paris Convention states that the Bureau International des Expositions (BIE) may grant recognition to:

“A1 horticultural exhibitions approved by the International Association of Horticultural Producers, provided that there is an interval of at least two years between such exhibitions in different countries and at least ten years between events held in the same country”

Since 1960, the Bureau International des Expositions (BIE) has recognised 22 Horticultural Expos.

Horticultural Expos foster cooperation and the sharing of knowledge and solutions between countries, horticultural producers and agricultural industries by addressing the paramount issues of healthy lifestyles, green economies, sustainable living, education and innovation.

Horticultural Expos are organised by a host country, last from 3 to 6 months and take place on a site of at least 50 ha. Participants include Countries and International Organisations (Official Participants) as well as Cities, Regions, Companies, Civil Society and NGOs (Non-Official participants).

The next Horticultural Expo will take place in Beijing, China, between 29 April and 7 October 2019 under the theme “Live Green, Live Better”.
