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 23 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, and last up to 6 months. 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 Doha, Qatar between 2 October 2023 and 28 March 2024 under the theme "Green Desert, Better Environment".
