The International Association of Horticultural Producers (AIPH / IAHP) is an international organisation dedicated to promoting horticultural producers and held the international garden / flora festivals or expositions worldwide.
The organisation was formed in 1948 in Switzerland for the international marketing purposes and now supports breeders' rights, the environment and international exhibitions.
International festivals have been recognised by the AIPH since 1960 at a Floriade in Rotterdam.
At least 4 events were held including the 1999 World Horticultural Exposition in Kunming, China and Expo '90 in Osaka, Japan.
15 events were held in the 2000s including Floriade 2002 in Haarlemmermeer, Netherlands and an exhibition in Shenyang, China in 2006
